Incomplete Penetration Incomplete penetration happens when your filler metal and base metal aren’t joined properly, and the result is a gap or a crack of some sort. Check out the Figure below for an example of incomplete penetration. a common…
Gas Tungsten Arc Welding GTAW in welding is Gas Tungsten Arc Welding, it is one of the welding types like others SMAW, GMAW and FCAW. GTAW (Gas Tungsten Arc Welding) or TIG (Tungsten Inert Gas) is a welding process which…
UNDERWATER WELDING
When welded structures are hot-dip galvanized, the weld area cleanliness significantly affects the quality and appearance of the galvanized coating around the weld. If a coated electrode (i.e. a flux-coated welding wire/rod/stick) is used during welding, all welding flux and…
