Consider the physical properties, mechanical properties and chemical composition of the weld material
1. Structural steel welding, generally consider the principle of equal strength, choose to me...
Spot welding is a resistance welding method in which the weldment is assembled into a lap joint and pressed between two electrodes, and the base metal is melted by resistance heat to form a solder ...
The welding electrodes that leave the factory have been dried at high temperature and packaged with moisture-proof material, which usually prevents the coating from absorbing moisture. However, dur...
1. What is the purpose of steel annealing?
Answer: ①Reduce the hardness of steel and improve plasticity, so as to facilitate cutting and cold deformation processing; ②Refine the grain, uniform the ...
When welding stainless steel, the performance of the electrode must match the purpose of the stainless steel. Stainless steel electrode must be selected according to the base metal and working cond...
