There are 4 basic forms of electrode arc welding joint: butt joint, corner joint, T shaped joint and lap joint. (1) the force of the butt joint is even, the welding quality is easy to guarantee, and the application is the most widely used. (2) the force acting on the angle joint and the T joint is more complicated than that of the butt joint, but when the joint is at right angles or angles, these two joint forms must be adopted. They are similar to those under external force and can be chosen according to actual conditions. (3) the stress concentration and the additional bending moment are easy to be avoided when the lap joint is acted on. But because it does not need to open groove, it is convenient to assemble before welding, and it can also be used in plane connection with little force. Two, what are the main groove forms of electrode welding? The basic forms of welding head arc are I, V, U and X. I groove is mainly used for thickness of 1~6 Mm steel plate welding; V groove is mainly used for the thickness of 3~26 mm steel plate weldment; U groove is mainly used for thickness of 20~60 Mm steel plate welding; X groove is mainly used for the thickness of 12~60 mm steel plate welding, double face welding.
