570~980MPa High Tensile Strength Steel / Ar GTAW Filler Wire and Rod YT-70

Characteristics

YT-70 is a filler rod and a spool wire for GTAW (TIG welding) to be used with Ar shield gas.
The weld metal shows stable toughness at low temperature range down to -20°C. The weld bead shape is excellent since high fluidity of molten pool and high affinity between molten pool and base metal. It also suitable for uranami (sound penetration bead) welding.
The operability is good since the surface of the filler rod is smooth.

Applications

Gas Tungsten Arc Welding of 690MPa and 100ksi high tensile strength steel for offshore structures, pressure vessels, tanks, penstocks, turbine casings, crane and construction machineries. It is also suitable for uranami (Sound penetration bead) welding with back shielding.
