Welding as a maintenance and reclamation tool play a vitally important role in the healthy functioning of all major industries.  Advancement in welding technology has resulted in the development of high temperature resisting super alloys used in guided missiles, supersonic jet aircraft and nuclear power plants using the welding technologies such as laser welding, plasma and micro plasma welding.  Material thickness varying from as low as 0.1 mm to 500 mm can be successfully welded to X-ray quality welding standards.
