Jigs and fixtures are an integral part of welding operations. They are used to hold components in place during the welding process, allowing for precise and consistent welds. Jigs are typically more basic than fixtures, while fixtures often have more complex designs that allow for a greater degree of movement or customization. The use of jigs and fixtures helps ensure that welds are made with the highest level of accuracy and repeatability. This is especially important for welding operations involving complex parts or intricate designs.
