Heavy machinery as well as expensive tools may require repair welding in case of incidental damage. Another associated activity is the rebuilding and restoring of wear resistance in case of heavy duty tough service such as mining, steel processing and earth moving activities.

The welding of such components requires a serious removal of defects as well as contamination. Furthermore, the procedures of repair and hardfacing shall be well prepared. Types of applications include: Metal to earth, Abrasion, Impact and Metal-to-metal

Welding is mainly executed with manual electrodes or with tubular cored wires.

For cylindrical parts, such as pistons and caster rolls, however, submerged arc welding using Lincore products is certainly the most efficient process.
