WebContact Us. Welding is a fabrication process whereby two or more parts are fused together by means of heat, pressure or both forming a join as the parts cool. Welding is usually used on metals and thermoplastics but can also be used on wood. The completed welded joint may be referred to as a weldment. Some materials require the use of specific ...

Resistance Welding - an overview ScienceDirect Topics
WebIn comparison with mild steel, for example, the austenitic stainless steels have several characteristics that require some revision of welding procedures that are considered standard for mild steel. As illustrated in Table 2, the melting point of the austenitic grades is lower, so less heat is required to produce fusion. WebWhen a hot crack occurs on the weld metal, then it is termed as Solidification Crack and if it occurs in the HAZ then called Liquation crack. Causes of Hot Crack: 1. High concentration of residual stress 2. Rapid cooling of the molten weld pool 3. High thickness of base material 4. Poor ductility of welded material 5. High welding current 6. healthy food at panda express
