Welding Allied’s Galvanized Products:

Flo-Coat® Tubing… same process as welding bare steel

Our capabilities include MIG and resistance welding of tubing and plate stock to produce custom parts. Welding galvanized tube is done exactly the sameway as welding the same bare steel tube; the same welding processes, volts, amps, travel speed, etc. can be used without modification when the switch is made to galvanized tube.

A competent welding engineer should, however, review the welding electrodes which are being used for excessive silicon content, which can cause zinc penetration of the weld metal. The silicon in the welding electrode should not exceed 0.04% Welding galvanized tube is done exactly the same way as welding the same bare steel tube; the same welding processes, volts, amps, travel speed, etc. can be used without modification when the switch is made to galvanized tube.
