Checking an Ontario Machine Shop through Standards and Certification

Metal fabrication plays a huge part in the industrial world. The quality of large metal parts must be assured since subpar quality can and will lead to subpar results. After all, these large and sophisticated fabricated metals are used in crucial applications, such as bridges, gigantic valves and aquatic vessel components. These are simply applications where you want to eliminate, or at least minimize, risks. Read more

Boat Leak: Quick Fixes While Heading to Nearest Ship Repair Services

Back in 1911 during the launch of the ill-fated ocean liner Titanic, its engineers claimed that the ship was practically unsinkable. Of course, now we all know what happened to the mammoth ship 103 years ago—it hit an iceberg, which tore a hole through its hull, and not even its state-of-the-art ‘anti-sinking’ watertight door system could save it from its fate.

Factors in Choosing the Right Ontario Machine Shop for Fabrication

Metal fabrication encompasses a wide array of activities including welding, boiler-making, blacksmithing, millwrighting, and ironworking. An Ontario machine shop may provide a mixture of these tasks along with a mix of prototyping, machining, field operations, and other related services. IHS Engineering360, a global resource for engineering information, emphasized that these procedures are inherently dangerous and that’s why they are usually outsourced to specialized contractors who provide such services.

Appropriate Ship Repair Services Needed for Sustaining Vital Standards

Industrial millwright services play an important role in ensuring the continuation of essential standards on a large scale across different industries. In industrial applications, one of the most important components is logistics. This aspect becomes especially complex when involving overseas transactions. Ships, or any other type of aquatic vessels, must conform to a set of standards to ensure safety and environment-friendliness. Read more

Frequently Asked Questions About Fabrication

Fabrication Housings

Fabrication Housings

For many companies and applications, fabrication is more than an answer to various needs. It plays an integral role within the production, assembly, and more of parts. In addition it aids in assemblies, tooling, and the general production of equipment to mention just a few possibilities.

From medical devices all the way to the components in aircraft and automotive manufacturing processes, fabrication is heavily relied upon. However, this means that there are many questions about the various different types of fabrication as well. Here we will explain some of the types and uses and answer many of the most frequently asked questions we have received over the years.

For heavy fabrication, the capabilities include metal forming, cuts by lasers, shearing, basic welding services and more. Projects of any size from the prototype stage to complete production runs can be handled through heavy fabrication. Some example projects are structural assemblies, frame construction for heavy duty projects, fabrication of heavy plates, and much more. Mill operations from small to large be done. Material capabilities can include most alloys, carbon steel, aluminum, and stainless steel.


Question: What are some previous examples of heavy fabrication as requested by clients?

Answer: Some of our previously produced items include frames for tow motors, large tanks, and construction sidewalls.

Regarding The Fabrication Of Sheet Metal

Beginning at prototyping and finishing with production, sheet metal fabrication includes many different phases. These range from forming, punching, shearing, welding and much more. Also included is light gauge and heavy gauge construction for plates and frames. Clients in the automotive, medical, consumer product, and aerospace industries are served by precision sheet metal fabrication. Run for both close tolerance large fabrication and large volume production are also possible.

Question: Which types of materials can the lasers cut through? In addition, what is the maximum thickness that this material can be before it cannot be cut?

Answer: Steel can be cut up to .886 of an inch, stainless steel up to .7 of an inch, aluminum can be cut at up to .630 of an inch.

Regarding General Welding

When a project requires either close tolerance with extensive fixturing or simple production welding, it will generally use some form of precision welding to achieve these needs. No matter the size of a project, it will be done to very exacting specifications. Even on more complex projects simple weldments are possible. Large frames do not preclude this simplicity either.

The use of 2-station robotic welding can save both money and time. This is because it enable continuous and simultaneous production to take place.

Question: What is the meaning of the terms “Mig” and “Tig” in regards to welding?

Answer: Mig is short for Metal Inert Gas welding. This is a common use, high deposition rate process. The process involves wire being fed consistently from a spool during the welding process. This is sometimes referred to as “semi-automatic welding.”

Tig is short for Gas Tungsten Arc welding. This process involves forming an arc between the metal being welded and a tungsten electrode. This process is generally used when high quality and precision are necessary.

Common CNC Grinding Mistakes

The right grinding material requires that you consider the material hardness, the piece of metal to be worked on and the type of finish required.

The first mistake: Grinding wheel

Most of the grinding wheels are made up of the abrasive and the bond used for cutting and holding the abrasive in place respectively. The grit determines the size of the abrasive to be used. When the grit number is low, a smaller abrasive must be used.cnc grindingUsing a too coarse of grinding wheel for the surface finish may not give you the required results. Instead, you can obtain a finer finish by slowing down the dressing federate even though it can result in dulling the abrasive. A dull wheel generates more heat and result in a lot of grinding force that is not good for quality productivity. Using a grit that has sharp abrasive grains will give better results compared to a grit wheel with abrasive grains. The following chart gives the size of grit required for the given finish.

Mistake 2: Dressing

Regular dressing may not be necessary. In fact a proper grinding wheel can allow for grinding multiple wheels without necessarily dressing the wheel. If more material is removed from the abrasive grain, it becomes dull. Thus, dressing every part may not be necessary. Reducing the frequency of dress has an added advantage; it reduces the cycle time extending the life of the dressing diamond and the grinding wheel. This reduces the cost and enhances productivity.

Note: the diamond dresser can also have an effect on the quality as well as the general productivity. Thus, the simplest method of dressing is where a single point diamond is used. However, care must be taken when using this single point diamond since it requires frequent rotation. When this is done regularly, the single diamond will wear out and develop a flat.

A single point diamond that has developed a flat makes the abrasive grain to become dull even when the grinding wheel is dressed. To dress the grinding wheel rotary dressing which uses an electric spindle to rotate may be employed. The rotary dressing is thus, a better alternative since it provides a consistent dress and reduces the possibility of the dressing disc to wear and develop flats as it is in the case of a single point diamond.

The Demand For High Quality Welders On a National Level

Welding is the trade you want to be in, especially in Canada. Not only is the skill in high demand, but highly qualified welders cannot be easily replaced. At a national level there are upcoming projects that will heavily rely on welding and large fabrication, and meeting the welder demands for these projects over the next few years should prove to be a challenge.

A skilled welder is classified by the level of training they’ve received; obtained at trade school, or through a union program or possibly a college or university. Those who take part in a qualified program/course can expect to receive proper training to acquire the technical and technique they need to be classified a skilled welder. However, different courses and programs may deliver content in a different way. As for how a welder’s skill is measured, they need to take part in practical testing. An example of this is the CWB (The Canadian Welding Bureau) Welder Qualification.
