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 ...
TIG
1.Application :
TIG welding (tungsten argon arc welding) is a welding method in which pure Ar is used as a shielding gas and tungsten electrodes are used as electrodes. TIG welding wire i...
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...
The weldability of metal materials refers to the ability of metal materials to obtain excellent welding joints using certain welding processes, including welding methods, welding materials, weldin...
High-carbon steel refers to carbon steel with w(C) higher than 0.6%, which has a greater tendency to harden than medium-carbon steel, and forms high-carbon martensite, which is more sensitive to t...
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...
