Characteristics:
It is designed for welding of high tensile 590N/mm2 steel. Commonly used is flat or horizontal fillet welding. It is suitable for root pass welding of pipes and applied in welding Mn-Mo, Mn-Mo-Ni alloy high tensile steel.
Applications:
It is suitable for welding of high strength steel used in steel construction, pressure vessels, vehicles and bridges
Notes on Usage:
- Electrode Stick Out must be kept between 15-25 mm.
- Use 100% Argon as shielding gas and the flow rate must be controlled that recommended 7-12 Lit/min when arc current is 100-200 Amp and goes up to 12-15 Lit/min when arc current rises to 200-300 Amp.
- Proper welding parameter shall be adopted for better welding performance. problem.
