EXCELCORE 71T-1C
AWS SPECIFICATION: AWS A5.20 E71T-1C
JIS Specification: JIS Z3313 YFW 24
Other Specification: DIN 8559 SGRI C Y 42 32
Shield GAs: CO2
DESCRIPTION AND APPLICATION:
EXCELCORE 71T-1C is a flux cored-wire which is used for mild steel and 490Mpa and high-strength steel. Adopt DC reversed polarity, the penetration is deep and the impact toughness is good. It has excellent processing property, less smoke, gentle and stable arc, thick and easily removed welding slag, and good X RT. It is used for the welding of ships, storage tanks, containers, steelworks, boilers and pipelines, etc.
NOTES ON USAGE:
-
Use DC reverse polarity.
-
Because the penetration is deep, welding leg could be reduced, which also can reduce the deposit volume, to save the cost.
-
Maintain the purity of CO2 is above 99.9%, the flow is 20-25L/MIN.
-
The distance from wire end to contact tip are: Ø 1.2mm: 15-25mm; Ø 1.4mm: 17-28mm; Ø 1.,6mm: 20-30 mm.
-
To avoid blow holes in the weld, please clear the surface of base metal including oil dirt and rust before welding.
-
Use a draught-exclusion-device if the wind speed exceeds 2m/sec.
-
Because it is softer than solid wire, don't lock the forcking idler wheel or wire feed device too tight.
