Precautions for welding of hot-dip galvanized steel, hot dip galvanized: it's an efficient method of metal anti-corrosion, which may prevent rust, anti-corrosion and reduce wear. The rust-removed steel parts are immersed during a molten zinc solution of about 500 ℃, so the surface of the steel parts is attached with a zinc layer, so on achieve the aim of anti-corrosion. Common galvanized steel products are: Galvanized Steel Tube, Galvanized Steel Coil etc.. Galvanized steel may be welded as long because the welding conditions like welding material, welding surface, welding current, welding speed, and welding method are appropriate. Generally, the welding strength of steel won't be weakened, but with the rise of galvanized thickness, the range of appropriate welding conditions becomes narrow, which makes welding difficult. it's best to completely remove the zinc from the welded part during welding.
When welding galvanized steel, concentrate to the subsequent points:
1. plenty of smoke is generated during welding, and welding workers will have adverse effects on their bodies when inhaled. they have to wear masks or install smoke exhaust equipment.
2. After welding, the welding slag must be removed, and also the peeling a part of the zinc layer should be repaired with high zinc-containing paint or repaired with zinc welding.
The content of hot-dip galvanized steel welding precautions is here. Hot-dip galvanized steel pipes are used for transportation and construction. Hot-dip galvanizing may be a process technology that immerses steel, stainless-steel, forged iron and other metals into molten liquid metal or alloy to get a coating. Hot-dip galvanizing is that the most generally used and cost-effective steel surface treatment method within the world today.
