DETALII
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.
Caracteristici
- Rate de depuneri foarte mari
- Rezistenta crescuta la fisurare in prezenta hidrogenului si porozitati
- Arc moale cu patrundere redusa pentru un amestec minim cu materialul de baza
