Introduction:
1. TIG Welding and Its Benefits: TIG (Tungsten Inert Gas) welding, also known as GTAW, is an arc welding process by using nonconsumable tungsten electrodes to conduct the welding. The weld area is protected from atmospheric contamination by a shielding gas (usually an inert gas such as argon) and a filler metal. TIG welding demonstrates good properties of precise control of welding variables, superior quality welds, low distortion and free of spatter;
2. Resistance Welding and Its Benefits: Resistance welding includes resistance spot welding (RSW), resistance seam welding (RSEW) and projection welding (PW). Resistance welding utilizes electric current and mechanical pressure to create a weld between two pieces of metal. Weld electrodes conduct the electric current between the two pieces of metal until they are forged together. The resistance welding is fast, economical, easy automated and very suitable for high rate production.
Tungsten and Molybdenum Electrodes for TIG & Resistance Welding
With superb properties of high hardness, high temperature resistance, both tungsten and molybdenum are rare metallic elements used as TIG electrodes or resistance electrodes for carrying out good welding performance. Choosing appropriate tungsten and molybdenum electrodes for TIG & resistance welding depends on the material type, thickness of the base as well as AC/DC current. The type and shape you use helps determine the arc quality and welding performance you will achieve. It is always important to wisely choose tungsten and molybdenum electrodes for TIG & resistance welding for each application. Operators should wear respiratory protections and conduct dust extraction equipments frequently on the grindstone during grinding.
LTWM could provide tungsten and molybdenum electrodes for TIG & resistance welding in various kinds, such as ceriated tungsten electrode, thoriated tungsten electrode, lanthanated tungsten electrode, zirconiated tungsten electrode, pure tungsten electrode, yttriated tungsten electrode, composite electrode (rare earth tungsten electrode), etc.
