The Welding of Stainless Steels

The GTAW process, also known as the TIG (Tungsten Inert Gas) or WIG (Wolfram Inert Gas) process, is illustrated in the above fig-ure. The energy necessary for melting the metal is supplied by an electric arc struck and maintained between a tungsten or tungsten alloy electrode and the work-piece, under an inert or slightly reducing atmosphere.

Since this process also uses the brittle mode, micro-cracks called chippings are generated on the front and rear sides of the wafer. As a countermeasure for this problem, dicing before grinding (DBG) process is also applied. In this process, as shown in Fig. 2, grooving (half-cut dicing) is performed from the front side before grinding.
