WebLaser Hardfacing. Laser Cladding is a weld build-up process, and a complementary coating technology to thermal spray. It is increasingly used instead of PTA (Plasma Transferred Arc) welding and easily outperforms conventional welding methods like TIG (Tungsten Inert Gas) for advanced weld repair applications. WebHardfacing is the application of hard, wear-resistant material to the surface of a component by welding, thermal spraying, or a similar process, mainly to reduce wear. Hardfacing is used on original equipment as well as for the repair of worn components. ... Plasma Transferred Arc (PTA), Gas Tungsten Arc (GTA) and Laser are the major hardfacing ...
