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...
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...
E71T-11 and E71T-GS both belong to AWS A5.20 carbon steel self-shielded flux-cored welding wire (FCAW-S). They do not require external shielding gas and are very suitable for outdoor or gasless e...
There are three types of underwater welding: dry method, wet method and partial dry method.
Dry welding
This is a method in which a large air chamber is used to cover the weldment, and the welder ...
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...
Red head thoriated tungsten electrode (WT20)
Currently the most stable and widely used tungsten electrode is mainly used in the welding of carbon steel, stainless steel, silicon copper, copper, br...
