NOTES
| Note |
|---|
| ⁽¹⁾ Preferred polarity is listed first. |
| NOTE: The deposit is not machinable or forgeable. Cooling rate does not significantly influence abrasion resistance. Deposit will usually cross check. |
| If more than two-layer build-up is required, use Wearshield® 15CrMn (preferred), Wearshield® BU or Wearshield® BU30 for the preliminary layer or layers under Wearshield® 60. |
| On manganese steel, use Wearshield® Mangjet® or Wearshield® 15CrMn as build-up. |
| Preheat is not generally necessary except to be sure that work is in room temperature range 25° - 45°C (75° - 100°F). |
| However, preheat of 120° - 200°C (250° - 400°F) may be necessary to prevent heat affected zone cracking on high carbon steel or low alloy steel base metals. |
| If more than two layers must be used, or if cross checks must be eliminated, preheat to 650°C (1200°F). |
| Prolonged or repeated heating of manganese steel base metal over 260°C (500°F) can cause embrittlement and spalling. |
| Avoid base metal embrittlement by: • Limiting the temperature 260°C (500°F) at distances of 13 mm (1/2 in) away from the weld. • Minimizing the time at elevated temperatures. |
| The correct welding technique is a vertical electrode with a 3.2 - 4.8 mm (1/8 - 3/16 in) arc length. The large ball on the end of the electrode should never touch the puddle. This technique will give a smooth transfer, low spatter and smooth bead. |
