TIG or Tungsten Inert Gas welding is an arc welding process with a non-fusible electrode. With this welding, more robust and ductile seams are obtained which are less sensitive to corrosion than in other welding processes, as the protective gas prevents contact between the oxygen in the atmosphere and the weld pool.
Fields of application
TIG welding is suitable for all types of carbon steels, low alloy steels, stainless alloys, nickel alloys, aluminium and its alloys, copper and its alloys, titanium, magnesium and other non-ferrous alloys.
Automatic cell for assembly, orbital TIG and resistance welding of stainless steel components to obtain fluid conduit tube assemblies, which have an automated installation with adjustable fixed electrode.
By means of TIG and resistance welding, among other applications, we carry out assemblies consisting of tube, support and bushing. These are assembled and joined in an automated way with the use of two robots. Both work in the same cell, carrying out the operations of inserting the bushing into the tube and flaring both ends of the tubes. We subject both assemblies to leak checking and laser marking operations.
- Insertion of the bushing into each tube
- Mechanical fastening and orbital TIG welding
- Forming of the tube ends
- Spot welding of a support on each tube
- Laser marking and leakage control, using robots for the internal handling and exit of the assemblies to the outside.
