Approvals: TÜV, DB, CE
Application Areas:
- For joining quenched and tempered fine-grained high-strength steels such as:
- S460N to S690N
- S500W to S690W
- S500M to S690M
- For wear-resistant steels of the following brands:
- N-A-XTRA 56 to N-A-XTRA 70
- HARDOX
- CREUSABRO
- DILLIDUR
Preparation:
- Remove contaminants, cracks, and worn metal from the welding area. Bevel the joints with V-, U-, or X-profiles according to the thickness.
Preheating:
- Preheating depends on the carbon equivalent of the steel as well as the size, thickness, and geometry of the workpiece. Castolin Eutectic recommends:
- CE < 0.2: Preheating not required.
- CE 0.2 - 0.4: Preheating 100-200°C
- CE 0.4 - 0.8: Preheating 200-350°C.
- Note that 12-14% Mn steels should never be preheated and that the workpiece temperature during welding should be kept below 250°C.
Welding:
- Current Type: = (+) [Electrode positive]
- Possible Welding Modes: Short-circuit transfer, axial spray arc welding, pulsed arc welding. To limit heat input, prefer welding in the air-pulsed arc mode. The interpass temperature should not exceed the preheating temperature.
