Harris Products Group, 03SIB60, Welding Rod, Copper Silicon alloy; 1/8 in diameter; 36 in length; 10 lb

3 Silicon-bronze GTAW (TIG) welding alloy is used to weld similar composition base metals of steel and cast iron to copper, brass and bronze. Frequently used to "brass weld" coated sheet steels. It can also be used to weld on galvanized steels. Conforms to AWS A5.7.

Notes

• All parameters are suggested as basic guidelines and will vary depending on joint design, number of passes and other factors.

Features

• Embossed on each end for easy identification after use
• Use DC+ or AC current and a 2% thoriated tungsten
• Can be used in all welding positions
• Silicon bronze base metals generally do not require preheat
• Use Argon for shielding gas
• Welding similar composition base metals, brass, and copper alloys to steel
• Frequently used in GTAW (TIG) "brass welding" of coated sheet steels
• Brass or copper base metals may require some preheat depending on copper content and thickness
