HOW TO WELD ESCO 14 SERIES MANGANESE STEEL ALLOYS
- Check with a magnet to be certain the part is a manganese alloy. ESCO 14 Series manganese alloys are not magnetic.
- Use filler materials as specified here.
- Bevel joints with torch, grinder or arc air equipment to obtain 100% weld penetration.
- Avoid overheating when gouging.
- Grind or torch cut work-hardened surfaces at least 1mm/ 1/32" deep before welding.
- Check with prickpunch to determine if all hardened surface has been completely removed.
- Scarf out cracks completely before welding.
- Skip weld. Make beads less than 125 mm/ 5" long.
- Avoid wide weaving beads in order to distribute heat evenly.
- Weld with short arc at low current setting "cold arc". You should be able to touch the part 150 mm/ 6" away.
- Peen each bead immediately to reduce contraction stress.
- Rebuild worn areas to original contour with austenitic manganese nickel electrodes to closely match the base material and allow work hardening.
