As its name indicates, this type of welding uses a tungsten electrode. This electrode is what gives current to the welding arc. Like GMAW, Gas Tungsten Arc Welding uses gas shielding. It’s commonly used for welding aluminum and magnesium. TIG welding can also be used to weld metals such ...

Vertical butt welds with single-V and double-V edge preparation, as well as vertical fillet welds are made much the same way as the downhand welds. In vertical welding it is a good practice not to use electrodes more than 4 mm in diameter, as with a bigger diameter electrode it is mor...
A welding electrode has an unalloyed or low alloyed iron core and an extruded coating containing iron powder, the iron powder having a bulk factor before and after vibration of at most 26.5 and 24 c.c. respectively per 100 gm. and consisting to at least 90% of granular matter having a ...

Welding beads play a critical role in the strength, durability, and appearance of the welded structure. Grasp their types, functions, and techniques for creating high-quality beads is essential for any welder. Proper heat control, consistent speed, appropriate electrodes, and a clean work environmen...
Other elements have proven to be superior to thorium for electrodes in every way. As you’ll see, there are a couple types of tungsten electrodes that are well suited for virtually any TIG welding task, either AC or DC 2% lanthanated tungsten (color-coded blue) is at the ...
Electric ARC Welding These welders can utilize eitherDC otherwise AC, & electrodes like consumable otherwise non-consumable. Generally, the welding location can be defended with some kind of shielding gas, slag, otherwise, vapor. This welding process could be manual, fully, or semi-automated. ...
electrodes while preserving most of its potential alloying benefits. The emissive fluxes used shield the weld arc from surrounding air, or shielding gases are used and nonemissive fluxes are employed. The higher weld-metal deposition rate of FCAW over GMAW (Gas Metal Arc Welding) has led to ...
