Can Galvanized Steel Be Welded?

Hot-dip galvanized steel welding precautions, galvanizing, also known as Hot-dip zinc and hot-dip galvanizing: is an effective metal corrosion protection method, which can prevent rust corrosion and reduce wear. The trusted steel parts are immersed in the molten zinc liquid at about 500°C, and the zinc layer is adhered to the surface of the steel member, thereby achieving the purpose of anti-corrosion. With the prohibition of cold galvanized steel pipes, hot galvanized steel pipes have developed rapidly, and more and more hot galvanized steel.

Can the hot-dip galvanized steel be welded?

As long as the welding materials, welding surface, welding current, welding speed, the welding method, and other welding conditions are appropriate, galvanized steel can also be welded. The welding strength of general steel will not weaken, but as the thickness of galvanizing increases, the range of appropriate welding conditions changes.

Greenhouse Steel Galvanized Pipe supplier believes that: hot-dip galvanized steel welding precautions, hot-dip galvanizing (galvanizing), also known as hot-dip galvanizing and hot-dip galvanizing: is an effective method of metal corrosion It can prevent rust and corrosion and reduce wear. The trusted steel parts are immersed in the molten zinc liquid at about 500°C, and the zinc layer is adhered to the surface of the steel member, thereby achieving the purpose of anti-corrosion. With the prohibition of cold galvanized steel pipes, hot galvanized steel pipes have developed rapidly, and more and more hot galvanized steel.

As long as the welding materials, welding surface, welding current, welding speed, the welding method, and other welding conditions are appropriate, galvanized steel can also be welded.

Generally, the welding strength of steel materials does not weaken, but as the thickness of galvanizing increases, the range of suitable welding conditions becomes narrower, making welding difficult. Therefore, it is best to completely remove the zinc in the welded part when welding.

When welding Galvanized Steel Pipe, the following points must be noted:

(1) A large amount of smoke is generated during welding, and the welding workers may have emotional adverse effects when inhaled, so it is necessary to wear masks or install smoke exhaust equipment.

(2) After welding, the welding slag must be removed, and the peeled part of the zinc layer should be repaired with high zinc-containing paint or repaired with zinc welding.

It can be seen that there is no special problem with welding. However, on-site welding is always harmful to the appearance, so as far as possible, bolt bonding is used.

The contents of the precautions for welding hot-dip galvanized steel is here. Hot-dip galvanized steel pipes are used for transportation and construction. Hot-dip galvanized steel is a process technology in which steel, stainless steel, cast iron, and other metals are immersed in molten liquid metal or alloy to obtain a coating. Hot-dip galvanizing is the most widely used steel surface treatment method in the world today with the best performance-price ratio.
