Welding Galvanized Pipe ASTM

Due to the presence of a zinc layer, welded galvanized steel pipe requires careful preparation and some extra precautions. Here are the things you should follow.

Preparation. Make sure the surface of the steel pipe is clean and free of any debris or contaminants. Use a wire brush or grinder to remove any rust or scale. Then, wipe the surface with a clean cloth to remove any dirt.

Safety precautions. The fumes produced when welding galvanized steel can be toxic, so it is important to take proper safety precautions. Wear respirators, gloves and eye protection.

Choose the correct welding process. MIG and TIG welding are the most common processes used to weld galvanized steel. Stick welding is also an option, but it can be more difficult to control the heat input.
Adjust the weld settings. Adjust the weld settings to account for the additional heat required to burn off the zinc layer. Higher voltages and wire speeds may be required to achieve a good weld.
