Welding has always been related to sheet metal manufacturing. There are procedures in the creation of parts or products that cannot be achieved with technology. Complex assembly calls for welding at times, and most manufacturing companies are ready to handle it using a procedure called “Gas Tungsten Arc Welding” (also nicknamed GTAW)
This modern welding method is known for being one of the cleanest manufacturing procedures used in the industry right now. It doesn’t create any slag or fumes, and the finished products look amazing once they are done. GTAW is used to create multiple parts for planes and boats. The use of welding requires some expertise, and we are willing to share that knowledge with you.
Here are some tips when you need to weld sheet metal for a project:
Follow the “One for One” Principle
Sheet metal manufacturing on carbon steel calls for one amp of power, one each of thickness. Other metals such as stainless steel and nickel call for reduced power, but you can apply this principle on materials such as magnesium and aluminum.
Use Cooper Chill Bars
Copper chill bars have argon ports. Both materials are useful to keep the heat at bay in your welding space. Your sheet metal fabrication will look cleaner.
Make Sure to Cover the Backside of the Part
This step is required when you are dealing with thin metal sheets. If you cover the backside of the welded part, you will prevent any form of oxidation. It can also be helpful to reduce the heat input so the welded piece will be clean with no cracks.
Try to Back Step the Welded Part
If you are welding a large piece, you can break the seam in evenly-sized parts to scatter the heat properly. This will reduce the solidification rate of weld residues and increase the thickness of the welded side to make the union more solid.
Use Big-Sized Cups
Large cups with a 16-17” diameter are the best to weld sheet metal since they offer broader coverage against the heat in the welded zone. It will also improve bead quality and reduce heat input.
Make Sure to Use Gas Lens
Welding torches working with gas lens prevent sudden movements as you handle the task. They also widen the area of gas coverage and help extend the electrodes to reach secluded spaces. They also improve the general outlook of the work being done.
These tips are handy tidbits of knowledge collected among the many technicians handling welding jobs in our factories. Any manufacturer worth their salt has trained professionals ready to handle these types of tasks that can only be done by a human hand.
