F07800 - SEMI F78 - Practice for Gas Tungsten Arc (GTA) Welding of Fluid Distribution Systems in Semiconductor Manufacturing Applications StdVol-Gases This specification is intended for1 Purpose 1. 1 The purpose of this Practice is to provide procedures for welding stainless steels and other corrosion resistant metals and alloys (CRAs) for fluid (liquid or gas) distribution systems in semiconductor manufacturing applications. Welds performed following these procedures are of sufficient quality to provide the required system purity, weld integrity, and weld strength for use in semiconductor manufacturing applications. 2 Scope 2. 1
