The selection of welding method for joining stainless steel pipes is dependent on: Other forms of resistance welding are high-frequency resistance welding, percussion welding, etc. Continuous tube mills use this process quite extensively. The non-heat-treatable stainless steels are easily weldable by this process. All types of stainless steel can be welded using flash welding. The basic sequence of flash welding of stainless steel is:įlash welding machines are manual, semi-automatic, or fully automatic and can perform various additional operations like pre and post-heating, clamping, shearing, flash trimming, etc. In the flash welding process, the work parts initiate a flashing action from the current delivered through the clamped electrodes. The butt welding process can be grouped into two classes Flash Welding and upset Welding. Stainless Steel Welding by Butt Welding Process: Projection welding can be performed in almost all stainless steel. At these projections, heat is concentrated and can be made in one or both pieces as shown in Fig. Localized welding is performed at predetermined points by projections, embossments, or intersections. Projection welding is best suited for heavy-gauge stainless steel workpieces. Universal Welding of stainless steel with Projection Welding:.The parameters that affect the welding process are:Ī typical process of spot welding is shown in Fig. ![]() The welding cycle consists of squeeze time, weld heat time, hold time, and off time. The process uses two water-cooled electrodes or wheels which are brought together with the work parts using a mechanical force by foot, air, hydraulic, or motor-operated cam. The contour of the electrodes limits the shape and size of the welds. In spot welding of stainless steel, coalescence is produced by the heat generated from electric resistance and pressure on the electrodes.
