Bohler UTP 8 (Joining & Repair-Cast iron) Special Application Stick Electrodes
UTP 8 is for cold welding of grey and malleable cast iron and cast steel and for joining these base metals to steel, copper and copper alloys, especially for repair and maintenance. UTP 8 has excellent welding properties. The easily controllable flow permits spatter-free welding in all positions and with minimal amperage. The weld deposit and the transition zones are fillable. No undercutting. Ideally suited for the combined welding with the ferro-nickel type UTP 86 FN (buttering with UTP 8 and filling with UTP 86 FN).
Features
- Spatter-free arc across all standard positions
- Stable arc and high puddle control
- Can be used in multiple welding positions, including flat (PA), horizontal (PB), and vertical-up (PF).
Technical Data
- AWS A5.15, ENi-Cl
- EN ISO 1071, E C Ni-Cl 1
- Chemical Composition: Pure nickel core (~99.5% Ni, 0.5% C)
- Weld Metal Hardness: Approx. 150–175 HB, ensuring the weld and transition zones remain soft and easily machinable with cutting tools.
- Current Type: AC or DC (-)
