Visual inspection for gas tungsten arc (GTA) welding of stainless steel and other corrosion resistant metals and alloys in liquid or gas fluid distribution systems in semiconductor manufacturing applications, in the SEMI F81 standard developed within the framework of an international standards program called International Semiconductor Equipment and Materials (SEMI). and acceptance criteria. These criteria are intended to ensure welds are of sufficient quality to provide the necessary system purity, weld integrity, and weld strength for use in semiconductor manufacturing applications.

The SEMI F81 standard describes the inspection and acceptance criteria for GTA (gas tungsten arc) autogenous butt joint welds of stainless steel and other corrosion resistant metals and alloys in fluid distribution systems. The fluid distribution system includes piping, pipe fittings, valves, sub-assemblies, and components that contain and distribute fluid.
Gas tungsten gas (GTA) welding is an arc welding method that uses a non-consumable tungsten electrode to produce the weld. The weld area and electrode are protected from oxidation or other atmospheric contamination with an inert shielding gas of argon or helium. A filler metal is usually used during the process, but some welds, known as autogenous or fusion welds, do not require it.
Gas tungsten arc welding process is a widely used process for joining similar and dissimilar metals because of the high quality results. Heat input and speed are the biggest advantages of this process. With these advantages, it is used for coating, welding with root joints and filler welding in various industrial applications.
While preparing this standard, the following SEMI standard was taken as reference:
Among the numerous test, measurement, analysis and evaluation studies it has given for businesses in various sectors, our organization, with its trained and expert staff and advanced technological equipment, provides visual inspection and inspection of gas tungsten arc (GTA) sources in fluid distribution systems in semiconductor manufacturing applications within the scope of SEMI F81 standard. It also provides testing services for acceptance.
