Mechanical properties of deposited metal:
| Tensile strength Rm (Mpa) | Elongation ratio (%) | Shielding gas | ||||||
| Test | 580 | 40 | 98%Ar+2%O₂ | |||||
Reference current (DC+)
| Diameter (mm) | φ0.8 | φ1.0 | φ1.2 | |||
| Welding Current (A) | 70~150 | 100~200 | 140~220 | |||
Precautions:
- Shielding gas: pay attention to the purity of shielding gas, it is recommended to keep the mixed ratio at Ar + 1~3% O₂.
- Gas flow: 20~25L/min.
- Dry extension length: 15~25min.
- The rust layer, moisture, oil stain, dust, etc on the welding part shall be clearly removed.
Welding Position: H, OH, HF, F, VD, VU
