AWS A5.5 E10018-D2 H4R

Notes on Usage

Welding Positions:

1.Dry the electrodes at 350℃∼400℃(662~752℉) for 60 minutes before use
2. Adopt back step method or strike the arc on a small steel plate prepared for this particular purpose because are striking on the base metal is danger of initiating cracking.
3. If each pass welds becomes thicker than acceptable level by high amperage or low speed ratio application, the impact values and yield points will decrease.

4. Keep the arc as short as possible.

Applications
