AWS A5.29 E81T1-K2C
TOKO AWS A5.29 E81T1-K2C, is Co2 gas shielded low temperature carbon steel alloy flux cored welding wire, which is designed for welding 560 N/mm2 high tensile strength steel for low temperatures. The weld metal contains about 1.5%-Ni and makes good notch toughness at temperatures under -60ºC of welding condition.it is known for providing great wetting and tie-in on joints. It is very easy to use and is great for high speed welding.
It provides excellent usability with stable ARC and efficiency in all-positions of welding. It is suitable for butt or fillet welding of offshore steel structurest, petrochemicals engineering, shipbuilding, pressure vessel, LNG and LPG carriers, and storage tanks, etc.
Flux-cored arc welding (FCAW or FCA) is a semi-automatic or automatic arc welding process. FCAW requires a continuously-fed consumable tubular electrode containing a flux and a constant-voltage or, less commonly, a constant-current welding power supply. An externally supplied shielding gas is sometimes used, but often the flux itself is relied upon to generate the necessary protection from the atmosphere, producing both gaseous protection and liquid slag protecting the weld. The process is widely used in construction because of its high welding speed and portability.
