: When welding GI pipes, ensure that you work in a well-ventilated area or use local exhaust ventilation. Welding on galvanized materials can release zinc fumes, which can be harmful if inhaled.

: Employ proper welding techniques to minimize the heat-affected zone (HAZ) and reduce the risk of damaging the zinc coating. Control the arc length and travel speed to maintain control over the heat input.

Post-Weld Inspection

: If the zinc coating is compromised during welding, consider applying a zinc-rich paint or coating to the welded area to provide additional protection against corrosion.
