Galvanizing, also known as galvanizing and galvanizing, is an effective way to prevent corrosion and reduce wear. After rust removal, the steel members are immersed in a molten zinc solution at about 500 ℃, which makes the steel members surface adhere to the zinc layer and plays an anti-corrosion role. With the prohibition of cold galvanized steel pipe, hot-dip galvanized steel pipe develops rapidly, and hot-dip galvanized steel pipe is more and more.
As long as the welding conditions such as welding material, welding surface, welding current, welding speed and welding method are suitable, galvanized steel plate can also be welded.
Generally, the welding strength of steel will not be weakened, but with the increase of galvanized thickness, the range of suitable welding conditions will be narrowed, making welding more difficult. It is better to completely remove the zinc from the welding part.
The following points shall be noted during the welding of galvanized steel plate:
(1) Welding produces a lot of smoke, which will have an adverse effect on the mood of the welding workers when they inhale, so it is necessary to wear masks or install smoke exhaust equipment.
(2) The welding slag shall be removed after welding, and the peeling part of zinc layer shall be repaired by high zinc paint or zinc welding.
Therefore, there is no special problem in welding. However, field welding is always harmful to appearance, so try to use bolts.
The hot-dip galvanized steel is used for transportation and construction. The hot-dip galvanized steel is a kind of technology to dip steel, stainless steel, cast iron and other metals into molten metal or alloy to obtain coating. Hot dip galvanizing is the most widely used method of steel surface treatment in the world.
