Welding chemicals help ensure your welds are free from spatter, cracks, leaks, and other defects. Anti-spatter sprays, anti-spatter gel, and anti-spatter solutions are applied to metal surfaces and equipment prior to welding operations so that spatter can be simply wiped away once the job is complete. Some metal treatment products remove unsightly heat discoloration from welded surfaces. Discoloration can reduce the material's corrosion resistance if not removed. Inspection dyes and penetrants are applied to the finished weld to reveal cracks, leaks, or other defects that can lead to weld failure.
