AWS A5.5 E8016-B5
Notes on Usage
Welding Positions:
1. Dry the electrodes at 350℃∼400℃(662～752℉) for 60 minutes before use.
2. Keep the Arc as short as possible, and avoid large width weaving.
3. Adopt back step method or strike the Arc on a small steel plate prepared for this particular purpose to prevent blow-holes at the Arc starting.
4. Preheat at 100-150°C (212~302℉). The temperature to be applied varies In accordance with plate thickness and kind of steel to be welded
