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...
What is flux-cored arc welding?
Flux-cored wire arc welding is a welding method that uses the arc between flux-cored wire and workpiece to heat, and its English name is simply FCAW. Under the actio...
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 ...
