Copper Polishing surface Internal thread bump welding stud.
Stud welding is a method in which one end of a stud is in contact with the surface of a plate (or pipe), and the arc is energized. After the contact surface is melted, a certain pressure is applied to the stud to complete the welding. Cylindrical head welding nails for arc stud welding are suitable for high-rise steel frame buildings, industrial plant buildings, highways, railways, bridges, towers, automobiles, energy, transportation facilities, airports, stations, power stations, pipeline supports, hoisting machinery and Other steel structures, etc. Stud welding is mainly composed of stud welding power source and welding gun.
Stud welding is to pass a stud (also can be a rod, tube or narrow strip) through different welding heat sources, and heat its end surface and plate, simplified arc surface or other partial surface of the body before pressure welding. This method is composed of contact Welding evolved. In principle, resistance welding, arc welding, electroslag welding, and friction welding can all be used for stud welding, but a stud welding gun that clamps the stud and controls the welding and pressurization process is required.
According to the different methods of stud welding, welding should be carried out according to the weldability of the recommended combination of stud material and base metal, otherwise there will be infusibility between the stud and base metal.
The combination of stud material and base metal outside the recommended range shall be tested to determine the weldability and product design requirements for relevant inspection and evaluation possibilities.
