The holes are in the floor and not the outside body. Welding equipment and competent to meet our customer s requirements. It is softer and finishes well while reducing the heat required to weld it. Lap welds because they cannot flex like the sheet metal around them will eventually show visible creases.

This of course creates a double thickness of metal at the joint overlap something that can be difficult to hide without using excessive amounts of filler. Gas welding joins metal using the heat of a torch burning both oxygen and a secondary fuel. It s also important to select a filler metal that is thinner than the base metal or as close as possible.
