In today’s world where welding technology is changing with each passing day, Shielded Metal Arc Welding (SMAW) is still active in the industrial field with its unique vitality. From steel str...
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...
Argon tungsten arc welding uses argon as a shielding gas to heat and melt the welding material itself (it is also melted when the filler metal is added) by means of the arc generated between the tu...
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 ...
Single-sided welding with double-sided formation is a core technique that welders must master, and it is particularly critical in the welding of pressure vessels and pipelines. It requires the wel...
Consider the physical properties, mechanical properties and chemical composition of the weld material
