TECHNIQUE
Cleaning
Grind root pass. Wire brush all passes.
FIELD TIPS — WeldIQ
▸Keep electrodes in a hot rod oven (250-300°F) until use. Low-hydrogen rods exposed >4 hours must be re-baked per manufacturer spec.
▸E6010/E6011: whip-and-pause technique for root. Listen for the crackle — consistent arc sound = good penetration.
▸Cellulosic rods produce heavy smoke. Ensure adequate ventilation, especially in confined spaces.
▸Open root: fit-up is EVERYTHING. Consistent root opening = consistent penetration. Check gap at least every 12 inches.
▸Use bridge tacks or tack from inside when possible. Tacks in the groove must be ground to feather edge before root pass.
▸Verify preheat with a temperature-indicating crayon (Tempilstik) or contact pyrometer. Check 3 inches from the weld on both sides.
