GETIG 7202

IDENTIFICATION : GEMIG 7202
CLASSIFICATION :AWS/SFA 5.7 : ER Cu Si - A , DIN 1733: SG- Cu Si 3

CHARACTERISTICS :

Silicon copper wire for tig welding

TYPICAL APPLICATIONS :

Welded joints and surfacing welds on copper-Zinc alloys and on low alloy cuprous metals. When making joints in silicon bronze, the low thermal conductivity must be taken into consideration. Preheating of the parent metal (silicon bronze) is not usually necessary. Joining copper alloys types,
Cu Si 2 Mn, Cu Si 3 Mn, Cu Mn 2, Cu Mn 5, brass, galvanised steel etc.

WELDING PROCESS : MIG

SHIELDING GAS : WELDING GRADE ARGON
