Welding Iron Electrodes. Tech-Rod 99 AWS class ENi-CI is a nominally 99 Nickel electrode. Using bare electrodes can be tricky because the arc is somewhat unstable and difficult to control.
To eliminate stresses the weld metal should be hammered whilst it. Cost machine-ability and whether the weld is single or multiple pass. We provide an extensive range of cast iron electrodes such as E NiFe-C E Ni-CI et Home.
Additions of iron powder in electrode coatings can be anything from a few per cent up to more than 60.
It is also useful on casting with relatively high phosphorous. The electrode welds with a mooth stable arc giving a flat dense and crack free deposit. JIS Z 3223 E6218-2C1M. In fact cast-iron electrodes have an easy ignition and a very steady welding arc.
