Spot Welding vs. TIG/MIG Welding

Resistance spot welding is a cost effective way to join two or more overlapping pieces of metal together. In addition, spot welding is a huge time savor compared to TIG or MIG welding. Many engineers come to VIP for advice to save time and money on sheet metal assemblies that require welding. One great method that we regularly recommend (depending on the assembly and function of the parts) spot welding as an alternative. Below shows a comparison between spot welding and welding (TIG or MIG).

Factors Resistance Spot Welding TIG / MIG Welding
Requires fixtures Yes Yes
Welding time Short Long
Requires grinding after welding No Yes
Requires skill and experience No Yes
Number of supplies needed
Minimal Several
Size of weld Small Varies
Material distortion Minimal to none Minimal to Extreme
