Choosing the Best Welding Process for the Job

What many people don’t realize is that welding can be far more complicated than it looks from the outside. What material are you using? What are the physical properties of that material? What’s the application for the finished component? These are just some of the factors that can affect how the welding project needs to get done, and what kind of welding process a manufacturer will have to use.

Some welding processes work better with different materials

The properties of the material are one of the most important things to take into account before starting the jobs. As you’ll see later on, some welding processes work better with different materials. Different materials are better suited to different industries and applications, and the choice of material can affect the welding process. For example, one material that we work with, aluminum, is perfect for industries where a manufacturer may want to reduce weight.

Gas Metal Arc Welding & Gas Tungsten Arc Welding

One type of welding we do is called gas metal arc welding. It’s an ideal process to use when you’re working with materials like aluminum, carbon steel, and stainless steel. It’s also important to mention that this particular welding process is generally faster than some other processes. Another welding process is known as gas tungsten arc welding, which can be used with all of the materials that we work with, from aluminum to stainless steel and carbon steel. One notable thing about this welding technique is that it’s known for its finer technique and slower process.

Our extensive experience in this field ensures that we choose the best, most efficient technique every time. That’s why we can confidently say that we’re your one stop shop for any manual or robotic welding needs.

Waterjet Cutting vs. Laser Cutting

At Harvan Manufacturing, we offer both laser cutting and waterjet cutting services. You may be wondering, just what are the differences between the two? While both methods can be used for applications in a wide range of industries, like aerospace, transportation, and energy, they differ in a few key ways.


The Difference Between Laser Cutting Materials and Waterjet Cutting MaterialsLaser Cutting

Waterjet cutting is the use of a high pressure stream of water and sand, and, while the procedure may be slower than laser cutting, it’s more suited for cutting thicker material. Additionally, it can handle some applications that laser cutting cannot.

Our laser cutting machines are used only for metal materials, with the exception of aluminum—which can be more difficult to cut on a laser. We use waterjet cutting for aluminum and non-metallic materials, like plastics, wood, and even stone.

While new advancements in laser cutting technology have increased the power of the equipment and have allowed lasers to make deeper cuts in thick materials like steel, waterjets are still the ideal way to cut through much thicker materials.


Choose Harvan Manufacturing for Industrial Cutting Services

We recommend using laser cutting because it’s a bit faster, but you can see that the material used, plus the thickness of said materials are the main considerations when deciding between the two. No matter the method, we pride ourselves on the ability to deliver high-quality components on time, whether it’s just a prototype or a small to mid-sized order of parts.

Harvan’s Manufacturing Process: From Design to Prototype to Final Product

We’ve thoroughly demonstrated our capability to take an idea and make it a reality in a quick and efficient manner in a previous blog, therefore, it should come as no surprise that we are highly skilled at every level. In order to better understand what we do at each production step, continue reading about our manufacturing process!

A Complete Breakdown of the Harvan Manufacturing Process

Drawing of a prototype for a bearing and a completed bearingStage 1: Prototyping


At times as a first step, we get requests from clients for prototyping work. With our in-house 3D printer, we take the design and print it out for the customer – according to their drawing and specifications. Then the customer can take the printed prototype and “interference fit” it into the assembly, to make sure it performs the job that they want it to do.

Harvan will sometimes find issues with the drawings that make it difficult to manufacture (adding to the cost), so Harvan engineers will make suggestions for modifications to the drawing/part in order for it to work from a manufacturing aspect.

Suggestions to remove details that add costs without changing the part’s function can be a part of the first step of prototyping.

Stage 2: Manufacturing Quote

The engineers then prepare a quote. They go out to source the material and then find good pricing for the material and incorporate that into their quote. Of course, the time to manufacture the part is factored into the final quote on the product.

Harvan will develop a “Bill of Operations” which is a detailed listing of what steps that it takes to make a part. Harvan uses Activity-Based Costing – each activity will have a particular cost associated with it based on the expense of the equipment used and the skill of the employee using that equipment.

Stage 3: Manufacturing the PartValue Added Services for our manufacturing processes

Once the order is received, the quoted method of manufacturing is once again reviewed by Harvan’s engineering staff to ensure that all the materials being used are the proper ones based on the TDP. In addition, the manufacturing process is also reviewed to make certain it is correct before going to production. This is a second line of quality control put in place in order to make sure all the specs are adhered to before the work order goes forward into production.

After engineering has a look, the engineers will qualify any welding to the standards recommended by either the Canadian Welding Board (CWB) or the American Welding Society (AWS).

Stage 4: Quality Control Checks

First-off Inspection – we run off one piece, and the machine operator will have someone other than the operator review to make certain it is correct. Afterward they do a 10% Inspection – so that every 10th part is inspected to make certain that the tolerance remains in place or if the machines need to be readjusted to meet the drawing. Finally, before the part is shipped to the customer, there is a Final Inspection to make certain the part meets the client’s full requirements.


Whatever your application or part may be, we want you to be assured that our engineering staff will piece together the perfect parts from beginning to end. We leave no step behind!

Solutions from Beginning to End

As providers of customized manufacturing solutions, we at Harvan Engineering are heavily involved in all aspects of our clients’ projects, and we are constantly working very closely with them from start to finish. In that aspect, we can be considered a one-stop-shop.

This means that sometimes we are asked to prototype parts, and sometimes we are prototyping without actually being aware of it. How so? A client might bring us a drawing and ask us to fix any problems and make it work, and we create a solution and are the first to actually make the part. In basic terms, this is prototyping, but for us, it’s just what we do to ensure our clients’ needs are fully met.

Oftentimes when we receive drawings, we see mistakes in the design—perhaps the tolerances don’t meet the overall dimension, or several design details mean something isn’t actually feasible. Perhaps with the tooling that is commonly available, something can’t be made as specified, or the material selection won’t work for how the part is made. Sometimes the standards don’t make sense; there can be different standards for the bar, sheet, and rod, and these details must be correct for drawing clarity.

Our job is to make the part manufacturable and to do so in a way that meets all of our customer’s needs and specifications. We draw upon over 25 years of experience and expertise in materials and manufacturing, so we can look at a drawing and help contribute to the design, giving solid solutions. We know that what is on paper has to be able to be manufactured, and that you can’t leave things open to interpretation. The TDP (total drawing package) needs to explain how a part is made.

Through our help in this process, we can save both time and money, ensuring no mistakes are made and that everything is easily achievable. Different departments within our company all have a role in reviewing the drawings and making sure everything makes sense, providing a complete, hands-on solution backed by true expertise.

We know that at the end of the day, time is precious and your product’s design must be flawless. Our experience and commitment ensures both your time and design’s integrity will be saved.

Sustainability in the New Year

Having a view of our world that includes being a sustainable member of the business community has increased over the past few years. Throughout the manufacturing and engineering fields, companies are working to make contributions toward a cleaner environment and a sustainable future. Everything from new approaches to manufacturing that reduce demand for resources that are scarce to the development of alternative energy sources like solar and wind are being tested and used by companies small and large.

We’ve seen companies use new advances in technology to use energy in a smart manner via automation systems. Engineers are constantly re-engineering systems and equipment in order to eliminate wasted materials, energy consumption, and even motion.

Here are a few of the things that we at Harvan Engineering have taken on over the past few years to become a more sustainable operation:

  • Recycle all of our scraps.
  • Recycling initiatives throughout our operations.
  • Reduce amount of paper that we use.
  • We have been working to ensure that any chemicals we use in processes are as environmentally safe as is available on the market.
  • We continually work to remove processes if they are unhealthy to our employees, our neighbors and to the environment in general.
  • Our lighting has been upgraded in the shop to save energy.
  • We have instituted an Environmental Policy, as part of our Health and Safety Management System, in order to have guiding principles to work from each day.

We are committed to becoming more sustainable for our employees, our community, and especially for our customers. We believe that we can develop and build products that are as good if not better via sustainable methodologies and practices. We look forward to progressing forward down this path in the New Year. Happy 2014!

Automation – Advantages and Disadvantages

Automation is utilized in many processes of today’s manufacturing sector. Many factories that are creating components and parts for a variety of industries have some type of the process automated. Robots are often used in more hazardous applications or in extremely repetitive actions that can be ergonomically problematic for human workers.

What are the advantages of automation and what are some of the disadvantages? Below is a list of advantages, with more information in this article, with some caveats to why each may be also a disadvantage if viewed from a larger perspective.

1. Decreased Overhead Costs – When a manufacturing company adds some element of automation into its production or fabrication of products, the competitive advantage is increased for the company. Through automation, the company will be able to reduce costs through elimination of staff and an increase in productivity (many robots can run 24/7). However, it is important to note that many automated systems and equipment are expensive, so these additional costs will have to be compared to the overall reduction of cost in the long run.

2. Increased Productivity – As mentioned above, many automated systems can work long hours, into the night and on weekends, which provides an overall increase in productivity. This increase in productivity, although beneficial, may be slowed by other non-automated factors, such as product finishing, final packaging, and shipping. A cost comparison of skilled workers versus an automated system with all the factors from start to finish is the best analysis to determine if increased productivity can offset any human staff-related costs.

3. Consistency, Reliability, and Accuracy – Automated equipment and robotics can manufacture and continually repeat consistent final product results. The addition of automation eliminates the common issue of human error that may detract from the overall quality of production. Manufacturing processes can be carefully regulated and manipulated in order to maintain overall quality. This is a key advantage of automated equipment—the human error element is greatly reduced providing assurance that parts and components will be of consistent high quality.

4. High Volume Production – Automation is a valuable resource when a manufacturer is producing high volumes of components or parts. However, it isn’t very useful for lower volume production, as the expense for tooling and operating the machines can often outweigh the overall cost of the finished product.

5. Increase in Safety – The use of robotics and automated equipment is an effective way to prevent worker injuries. Many of today’s automated production devices keep workers a safe distance from the more hazardous areas of work. Human staff is still needed to operate and program the equipment, but the actual hands-on work is left to the machine, protecting the health and safety of staff. In addition, robots are able to work in extreme environments such as very hot or cold areas of a manufacturing plant. This allows workers to be free of additional harm from elements harmful to humans.

Today’s manufacturing incorporates the skills of trained workers with the precision of automated equipment and robotics. This combination of automation and a skilled work force provides a strong operational base for North American companies to be competitive both here and overseas. What do you think? Is automation providing advantages for manufacturing or are there long-term potential disadvantages? Let us know!




Transporting North America’s Oil and Gas in the 21st Century

In less than a decade, North America has under gone a massive economic transformation thanks to the boom in the natural gas and oil industries. A recent report from the influential global information company IHS gives some insight into just how big the changes have been in the past six years. According to the IHS, this seismic shift in the global energy landscape gets credit for adding an average of $1,200 of discretionary income to the U.S. families, along with supporting upwards of 1.2 million jobs and contributing $284 billion to the GDP. In Canada, the oil and gas industry currently supports 550,000 jobs across the country and should create close to another 1 million jobs by 2035, according to this article.

With all of this oil close to home, what is the best way to distribute it across North America? Does it make more sense for the oil to be refined more locally and then distributed at that point? For years, North America’s relatively moribund domestic energy industry had little need for new infrastructure. However, that has all changed, and it has changed in a blink of an eye. Energy giant Exxon believes that North America will be exporting 15% of its natural gas and 5% of its oil by 2040. The two main forms of transporting oil and gas from the field to North America’s ports and transportation hubs are through pipelines and via rail or truck. Both forms of product movement have their benefits and their limitations.

Rail and Road

The first thing to point out is that there is already a vast network of rails and road throughout North America. Everyday 42% of our ton/miles of U.S. freight travels by rail, as seen in this article, while trucking freight saw a 3.9% jump in 2012 alone. As far as safety, while train accidents have declined 26% since 2000, they still occur. As we witnessed with Canada’s recent July train disaster, they can create high levels of doubt in the communities that they run through.


As of 2013, there are 409,000 miles of pipelines in the U.S. alone. This vast network of above ground and below ground pipelines carries roughly 17% of all ton/miles of U.S. freight. Pipelines do have some downsides, like higher initial expense; however, their pros generally outweigh the cons. The positives include:

  • Dedicated use and cost-effectiveness
  • Ability to transport large volumes
  • Unaffected by weather and can operate 24-7
  • Can reach more isolated oil and gas fields

Of course, as we mentioned, the cost of constructing a pipeline can be quite high, but they do provide less of a risk than rail transport.

In the end, both pipelines and rail/road transportation will continue to play critical roles in supporting the ever-growing North American oil and gas industries as long as they can maintain their feasibility, cost-effectiveness, and ultimately, a high-level of safety.
