There are some inherent problems in dissimilar metal welding that hinder its development, such as the composition and performance of the dissimilar metal fusion zone. Most of the damage to the diss...
Welding material standards are an important basis for ensuring welding quality and safety. Different countries or regions have formulated corresponding standards according to their own industrial n...
There is no difference in process between full argon arc welding and argon arc welding. Full argon arc welding is suitable for thin-walled small-diameter pipes (generally DN60 and below, wall thick...
With the rapid development of the petrochemical industry, stainless steel materials have been widely used, which has also put forward higher requirements for the welding of pipes and plates. The pr...
– FLUX–
Flux is a granular welding material. During welding, it can be melted to form slag and gas, which plays a protective and metallurgical role on the molten pool.
Constituent...
The welding residual stress is caused by the uneven temperature distribution of the weldment caused by welding, the thermal expansion and contraction of the weld metal, etc., so the welding constru...
