Product Description

CAST NIFE G x 1.2mm

CAST NiFe-G-12

CLASSIFICATION

EN ISO 1071:   T C Z NiFe-1 M

DESCRIPTION

  • Metal cored wire for semi-automatic gas shielded metal arc welding 
  • Designed for welding grey, malleable, nodular and phosphorous cast iron  
  • Welding of highly restrained or thick walled pieces 
  •  Preheat is not necessary. Heat input is low which favours limited H.A.Z.

APPLICATIONS

 Joining and surfacing highly restrained spheroidal graphite cast iron, grey cast iron and malleable cast iron pieces. Also used for dissimilar welds between cast iron and steel.

Casings for pumps and valves, frames, machining errors on castings, crushers, gear housing etc.

Examples

  • Lamellar grey cast irons DIN 1691 GG 10 to GG 40
  • Malleable cast irons DIN 1692 GTS 35 to GTS 64, GTW 35 to GTW 65
  • Nodular cast irons DIN 1693 GGG 40 to GGG 70

Recovery: 98 % 

For multiple pass welding in flat or downhand position, best penetration is obtained by pulling the torch at an angle of 70-80° to the axis of the joint. 

For fillet welds, the best bead appearance is obtained by pushing the torch at an angle of 60-70° to t he axis of the joint. Pulsed current optimises welding performance over a wide range of parameters with minimum heat input and also facilitates positional work.
