Specially coated electrode based on copper-nickel for machinable cast iron cold welding, for joint & repair welds on damaged grey iron castings & malleable cast iron components. The particular kind of coating permits the employment of low currents so that the component is only subjected to little heat. In the grey the chilling effect in the transition zones is reduced so that these can still be adequately malleable. The electrode has excellent welding properties and produces prefer and tight seams little spattering and easy slag removal.
Pickling tanks, pumps and pipe systems dairy vessels and pipe work, drug and food equipment, acid containing vessels and pipe systems. Machine tool bases and frames, Exhaust manifolds Oil and grease sumps. Gear and bearing cases Iron/steel construction connections.
