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. 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.
WebJan 20, 2015 · With GTAW, the welder must maintain a very short arc length while preventing contact between the electrode and the work itself, requiring a great deal of training, skill and care. Two hands are usually required with GTAW, as one hand will be operating the welding torch while the other hand feeds the filler metal into the weld being created.
WebOct 5, 2024 · As a good starting point, arc length should not exceed the diameter of the metal portion (core) of the electrode.

WebThe gas tungsten arc welding (GTAW) process is a very versatile, all-position welding process that is widely used to join Ni-/Co-base alloys. In GTAW, the heat for welding is generated from an electric arc established between a non-consumable tungsten electrode and the workpiece. GTAW can be performed manually or adapted to automatic equipment ...
WebThe arc length is the distance between the tungsten and the base metal, that the arc travels between. Arc stability is one of the difficulties encountered in TIG welding both steel, stainless and aluminum. It is arc length that is largely responsible for the stability of the arc itself, if gas flow and torch angle is correct. david aynesworthWebAn excessively convex or ropey bead indicates that voltage is too low. As voltage increases, arc length gets longer and resulting arc cone gets wider and larger.
