Welding work involves many industrial fields, welding fume is one of the most common hazards of welding work.
Welding fume is in the welding process when the welding rod and welding parts in contac...
– 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...
Welding current, voltage and welding speed are the main energy parameters that determine weld size.
1. Welding current
When the welding current increases (other conditions remain unchanged), the pe...
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...
First, Welding cracks and pores are generated.
The moisture absorbed by the welding rod becomes gas under the action of the welding arc heat, which decomposes hydrogen, resulting in the formation ...
