Shielded Metal Arc Welding (abbreviated as SMAW). The principle is: an arc is generated between the coated electrode and the base metal, and the welding method using the arc heat to melt the electr...
Welding stress and distortion is the stress generated in welded components due to welding. It includes internal stresses generated during the welding process and changes in shape and size cause...
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. Core principle: Why must we use argon?
During the welding process, the metal is like red-hot iron at high temperatures. If it is not protected, it will immediately combine with the oxygen and ...
