Welding Galvanized Beam. The best way to weld galvanized steel regardless of welding process is to remove the zinc coating from the joint. However galvanized steel can be welded without removing the zinc coating if special procedures are followed.

GMA welding also known as CO 2 13X or MIGMAG welding is a versatile semi-automatic welding process which is convenient and easy to use. X describes strengthening patterns such that C for the control beam L for plate welded to lower flange and U for plate welded to upper flange. Stud welding in the case of welding studs to a structural beam to connect a concrete deck to the beam is typically done using the electric arc stud welding process.
When using SMAW stick welding galvanized steel can be welded in the same manner as uncoated steel.
The dual laser beams method to lap weld galvanized steel sheets is being discussed modeled and analyzed involving a precursor beam and a higher-power actual beam used in tandem and generated. Good ventilation is essential. When welding galvanized steel white fumes of zinc oxide are produced. 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.
