Now the welding technology has become very important, and the technology has been greatly improved. Now the welding technology can perfectly deal with these internal and external defects. In fact, the mechanical property is equal to or has begun to be higher than the welds of these connecting bodies. The welding bodies only see the position in the space are actually welded joints, and the strength of the joints is generally In addition to the influence of weld quality, there are some geometric shapes and so on. There is a great relationship between the size and some stress conditions. The basic forms of joints are actually butt joints, some lap joints and so on.
