DETAILS

Deposit properties are optimized to display a high creep and scaling resistance and especially superior metal-to-metal wear resistance combined wlth oxidation at elevated temperatures on tool-steel parts.

Features

  • High thermal conductivity weld deposit retains its hardness and weld properties in service up to 650°C.
  • It’s also ideal for welding of high strength carbon steels and hot working steels.
  • Kobatek 544 produces thick multipass weld deposits that have a reduced cracking sensitivity compared to iron based electrodes of similar deposit hardness.
  • Exceptional weldability, stable arc, perfect metal transfer and high deposition rate (135%) reduces time and labor costs. Usually there is no need to apply buffer layer according to the base metal type.
  • Preheating of 150-400°C is necessary for massive work pieces depending on the base-metal composition.
  • Weld metal can be machined with tungsten carbide tipped tools.
  • Electrode should be inclined at a 45° angle in the direction of travel and should be operated with a medium to short arc distance.

Welding Positions

  • 1G/PA 2F/PB 2G/PC 3G/PF
