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...
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...
