FONTARGEN A/AF 314

FONTARGEN A 116 MWire electrode made of a Fe-Ni alloy for MAGM weldingDIN 8573: SG – Ni Fe – 2AWS A 5.15:Ni Fe – CIComposition, typical analysis (% w/w):C Mn Ni Si Cu Ti Fe0,2 1,0-4,0 45-60 0,2 1,5 0,3 RemainderCharacteristics / Applications:Cold welding of cast iron, black and white malleable iron. Nodular cast iron andaustenitic cast iron. Welding of alloyed grey cast iron tools in the automotive industry.Edge welds. Preheating only for critical parts (external cross-over sections at the platethickness) 100 - 200°C.To avoid excessive stress and the related risk of cracks, it is advisable to keep input ofheat to a level as low as possible, to weld in short step-backs and with cooling periods,and to gently remove welding layer by hammer. Good workability by machine. Numberof layers: max. 4 layers.Mechanical properties of pure welding deposit(Min. values at RT):Tensile strength:approx. 500 N/mm²Elongation (l=5d): approx. 25 %Hardness HB 30:165 – 175 HBWelding process:MAGM, pulsingShielding gas (DIN EN 439): M13 (Ar+1-3% 0 2 )M12 (Ar+2-5% C0 2 )M21 (Ar+15-25% C0 2 )Current mode:DC (+pole)Availability: Diameter (mm): 1,0/1,2Spool type:B300Welding position: according to DIN EN 287PA PB PC PD PE PF PG08/08/Eb/0146
