DETAILS
Designed for very high deposition rates and increased resistance to hydrogen cracking and porosity on steel containing sulfur or contaminates. Recommended for single or multiple pass welding on carbon steel and some low alloy steels in applications without impact strength requirements.
Features
- Very high deposition rates
- 增加抵抗ance to hydrogen cracking and porosity
- Soft, low penetrating arc for minimal base material admixture
