DETAILS
An excellent electrode for repair of casting defects and with optimum machinability.
Features/Characteristics
Electrode with excellent welding characteristics. The deposit is machinable and crack-proof. Good bonding on difficult to weld cast iron.
SME A19 Welding Rod Uses/Applications
Electrode for cold welding of cast iron without preheat and for joining cast iron to mild steel. Also suitable for surfacing cast iron parts subject to erosion, corrosion and high temperatures. Best suited for repairing intricate cast iron parts, water pump housing, electric motor bodies and covers, machine frames, cylinder blocks and gears. Also ideal for salvaging foundry castings, gear box, differential housing, lathe beads, sugar mill rollers, glass moulds and cast iron dies.
Welding Technique/Procedure
Clean the welding surface for cracks and defects. Drill holes at ends of cracks and vee out using SME I00, Use a short are with low current to deposit stringer beads 25 to 75 mm long at a time. Hot peen the deposit to reduce residual stresses. Use skip welding technique. Cool slowly.
