The lap joint, which is used when making a lap weld, is very forgiving to varying part dimensions.Difference Between Socket Weld and Butt WeldAs with socket weld, a pipe is inserted into a recessed area of the fitting. Both the pipe and the fitting are square cut, with no need for beveled end or preparation other than cleaning the outside, which allows easy welding and installation. Just as its name implies, is socket welding in the pipeline which forms angle welding. lap welding pipe
