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...
Vertical welding with stick electrodes gives many welders trouble. The molten metal wants to drip downward, the puddle sags, and the bead ends up uneven. But vertical welding is not as hard as it...
Welding is the core processing technology in the fields of modern manufacturing, steel structures, pipes, sheet metal, auto repair, and special equipment. According to the physical nature of the ...
