Bevel of butting weld
Thread Content
Beginner’s question: For butt welds, it is required that the edges be aligned; why isn’t an angled edge acceptable? Is it because the groove is difficult to prepare, or is there some other reason?
You are referring to the butt welding of pipes, right? Yes, the grooves are difficult to prepare; moreover, this leads to irregular welds, which not only increases the difficulty of welding but also affects the quality of the weld. If it is sheet metal or section steel, bevel jointing is possible.
