CEWELD AA 4820 is for welding cap layers for joining refractory Cr-Al-Si steels. Cladding corrosion resistant overlays. Cladding heat resistant overlays up to 1100ºC.
Cladding components in a sulphurous environment.
Higher productivity, higher deposition rates and improved wetting properties compared to solid wires with comparable analysis. Excellent weld metal quality and X-ray soundness.
When welding, care should be taken to minimize the heat input, because materials of this composition have a tendency to embrittle in the temperature range of approx. 600-800° C. The interpass temperature should not exceed 300° C. Therefore, the interpass temperature should not exceed 300°C.
