Maintenance & Repair Industries

APPLICATION REQUIREMENTS
Welding of heavy machinery and expensive tool components requires a serious removal of defects, as well as contaminations.
Repair welding :
When drawing up a plan, the following issues have to be taken into account:
- removal of all defects
- joint preparation
- welding processes and welding consumables
- preheat and interpass temperatures as well as post-weld heat treatment
- environmental circumstances
- welding procedures and execution
- mechanical post-weld treatment of the welds

Build up  and hardfacing :
Restoring worn parts normally consists of three steps:
1. Buttering for a deposit that will dilute the carbon and alloy content of base material and the risk of cracking.
2. Build upseriously worn areas must be rebuilt close to working size using tough, crack resistant welding materials, which can be deposited in an unlimited number of layers.
3. Wear resistant surface layers.

The type of wear resistance determines the type of consumable that is selected. Wear resistance, coupled with elevated temperatures, can be sub-divided into:
- sliding, rolling, metal-to-metal (friction) - moderate and/or severe impact
- moderate and/or severe abrasion.
Hardfacing is usually limited to one, two or three layers.
