As global attention to environmental protection issues continues to increase, all walks of life have begun to seek green and environmentally friendly production methods. The welding industry is no ...
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...
The submerged arc welding process is the most ideal choice in the important application fields of pipelines, pressure vessels and tanks, track manufacturing and major construction. It has the simpl...
Consider the physical properties, mechanical properties and chemical composition of the weld material
