As long as the welding materials, welding surfaces, welding current, welding speed, welding methods are appropriate, and galvanized steel can also be welded.
Generally, the welding strength of the steel will not weaken, but as the thickness of galvanizing is increased, the proper welding conditions are narrowing, so that the welding is difficult, so it is best to completely remove the zinc of the welding department during welding.
When welding of galvanized steel, pay attention to the following points:
(1) A large amount of smoke is generated during welding. Welding workers will have emotional adverse effects when inhaling, so we wear masks or smoke exhaust equipment.
(2) After the welding, the welding residue must be removed. The zinc layer peeling part is repaired with a high -containing zinc paint or a zinc welded melting.
It can be seen that welding is not special. But on -site welding is always harmful to beauty, so it is used as much bolts as much as possible.
The hot -dip galvanized steel pipe is used for transportation and construction. Hot -dip galvanized is a process technology that immerse metals such as steel, stainless steel, and cast iron into melt liquid metals or alloys to obtain plating.
The advantages of hot -dip galvanized are actually more than anticorrosive. It has low treatment costs: the cost of hot immersion galvanized rust and anti -rust is lower than the cost of other paint coatings;
The second long -lasting durability: Standard thermal galvanized rust -proof thickness can be maintained for more than 50 years without having to repair it;
The third reliability is good: galvanized layer and steel are a combination of metallurgy, which becomes part of the steel surface, so the durability of the plating layer is more reliable;
The toughness of the fourth coating: Galvanized layer forms a special metallurgical structure. This structure can withstand mechanical damage during transportation and use;
Fifth comprehensive protection: Each part of the plating can be plated with zinc, even in the depression, the sharp corners, and the hidden place.
Sixth province and effort: The galvanized process is faster than other coating construction methods, and the time required for painting on the construction site after installation can be avoided.
