SA213 P11 Nickle Alloy CMT Cladding For Power Station Long Lifetime 60.5x3.8x6000mm
Production Information of CMT Cladding
Surfacing welding is a welding process in which a layer of wear-resistant, corrosion-resistant and heat-resistant metal layer is deposited on the surface or edge of the workpiece, and the metal is melted by electric welding or gas welding and stacked on the tool or machine parts

The most common problem in surfacing is cracking. The main methods to prevent cracking are as follows
1. Preheat before welding, control interlayer temperature and slow cooling after welding
2. Stress relief heat treatment after welding
3. Avoid multi-layer surfacing and use low hydrogen surfacing electrode
4. If necessary, build up the transition layer between the surfacing layer and the base metal (use the electrode with low carbon equivalent and high toughness)
Attention must be paid to butt welding:
1. According to the use requirements, reasonable selection of surfacing alloy
2. Reduce the dilution ratio of base metal as much as possible
3. Improve productivity
4. It is expected that the hardfacing metal and base metal have similar expansion coefficient and phase transformation temperature
Purpose of surfacing welding of CMT Cladding:
1. Reduce costs
2. Extend service life
3. Reduce maintenance
4. Reduce spare parts
