Welding is a commonly used, though expensive, technique in metal fabrication. Overall welding costs can be reduced or eliminated by incorporating spot welding when appropriate. In this article, we are going to discuss spot welding, and how it can save money and improve quality in a metal fabrication project.
What is Spot Welding?
Spot welding is the process of passing an electrical current through two pieces of metal that are situated between electrodes. The electrical current causes the metal to melt at that precise spot, creating a weld joint. This is what gives the process the term “spot welding.”
Most importantly, spot welding focuses the weld process on a very small area, which limits the heat distortion introduced into the part. As an added benefit, this process also reduces the finishing requirements after welding is complete.
What are the Benefits of Spot Welding?
Because spot welding requires two parallel surfaces to press between the electrodes, the parallel surfaces are an ideal location for incorporating self-locating features that eliminate the need for fixtures or tools.
Using spot welding instead of typical welding has many benefits, as it allows you to better control:
- Heat distortion
- follow up finishing requirements
- The need for fixtures and tooling
It’s important to note that spot welding can’t replace traditional welding. But, when appropriate, it is a viable substitute for welding. This can improve quality and reduce costs.
