The completion of entire assemblies includes joining by welding. The use of this inert gas welding processes such as metal active gas (MAG), are the metal inert gas (MIG) or Tungsten Inert Gas (TIG) and plasma tungsten arc welding (micro plasma or plasma). In addition, the arc and spot welding and brazing and soldering is used.
In addition to these different methods for joining ferrous or non ferrous metals and hot-air welding method for joining plastics. With a helium leak detector, the welds are checked for leaks.
