How To Arc Weld Galvanised Steel. The controlled fine droplet spray transfer produced by pulsed GMAW results in a more stable arc than with short-circuiting so more joint types and a wider range of material thicknesses can be joined. The welding conditions necessary for galvanized steel welding by SMAW and MMAW are similar to those used on uncoated steel.

However it still holds its place. The zinc coating should be removed at least 1-4 inches from either side of the intended weld and on both sides of the workpiece. Welding Galvanized Steel by SMAW MMAW.
Comments section says maybe only a couple of minutes is required to remove the Galveston and not the 24hrs or so he used.
Weld on galvanized steel. A short arc length gives better control of the weld pool and helps to prevent either intermittent excess penetration or undercut. Welding of thinner gauge galvanized steel can be done using direct current electrode negative straight polarity 116 diameter EWTh-2 tungsten pencil-sharpened with a 132 flat end ER70S-2 or ER70S-3 filler metal argon shielding gas and the following parameters.
