WebNov 27, 2024 · The three most commonly used shielding gases to GTAW weld are: Argon / Ar (typically used) Helium / He Argon/Helium He/Ar mixtures Since Argon and Helium are inert gases they do not change the characteristics of the weld joint. In some rare cases there are three types of gas mixture used. WebSep 19, 2024 · Arc length is the distance of the electrode tip from the workpiece. You should hold the welding torch so that it hovers above the area that is to be welded without making any contact. If you are right handed, then you should move the torch from right to left. The direction of weld travel should be reversed if you are left handed.

WebThe longer the distance, the greater the air gap, and the greater the resistance that needs to be overcome in order to generate an arc. Arc voltage correlates directly with arc length, as the longer the arc is, the more voltage is required to overcome the resistance. WebThe length of the arc in turn determines the width and size of the arc cone. As arc length decreases, the arc cone becomes narrower and the arc is more focused (see Figure 7 ). …

WebDec 1, 2007 · The proper arc length when welding alloy metals is as tight as possible—on the verge of touching the metal. A tight arc produces a well-defined puddle and better directional control, which is necessary when dealing with a sluggish weld puddle.
