This adds two operations. When using MIG or flux cored welding one may have to adjust the voltage slightly to control spatter and one may have to clean the welding gun of spatter and zinc oxide deposits more frequently that when welding uncoated steel. Set the coupling end with the drawn line on the pipe with an aligned mode.

It depends on what you are welding and how critical the application. When using MIG or flux cored welding one may have to adjust the voltage slightly to control spatter and one may have to clean the welding gun of spatter and zinc oxide deposits more frequently that when welding uncoated steel.

Gas metal arc welding also known as Metal-Inert Gas MIG welding is a versatile semi-automatic welding technique particularly suited for the welding of thinner materials Welding speeds for GMAW are typically slower for galvanized surfaces. Welding specifications are derived from the American Welding Society AWS 0190 Welding Zinc Coated Steel.

They were made from galvanized sheet metal and we didnt clean crap. Grind off the coating on the weld area plus 12-inchc zinc coating and it melted and smeared into the ground area. Weld around the edge of a tear and work your way in.

Any Arc Welding Process General Recommendations. Galvanized piping can be a tad tougher to weld due to the related fusion if you do not remove all of that coating. This specification relating to the preparation of the metal and the actual welding process calls for the weld to be made on steel that is free of zinc although the component has already been galvanized.
