CAST IRON ELECTRODE

R995.00R1,270.00

Description

Descriptions
99% Nickel cast Iron electrode

Characteristics
Specially developed for all cold welding of cast iron, the ISOARC 210 is ideal for positional work. Extra-low heat input, high strength and fully machinable deposits result from using this electrode, extremely pure, the 210 is a low hydrogen electrode with graphite.

Applications
Can be used to cold-weld cast iron to steels, brass, bronze, thin and medium thick sections. Applications include: motor blocks, machine bases, motor and gear housing, cams, bearing blocks, transmission cases and machinery parts.

Procedures
Superior bonding is possible on heavy sections by local preheating to a maximum of 100 degrees. Use a short to medium arc at the lowest amperage possible. Peen lightly to relieve stresses. Skip weld, and back-step to avoid heat and stress accumulation. Before welding the repair area must be machined or ground clean. If ground, remove carborundum particles with an oxidizing flame, searing the area to be welded. Depending on wall thickness, a U or double U welding preparation must be made. Use a short arc and keep the electrode at a steep angle. Remove slag and peen lightly. Always restrike on the weld deposit and never on the parent metal as this induces thermal shock.

Descriptions
55% Cast Iron electrode

Characteristics
Use for cold welding all types of cast iron. Particularly recommended for pressure tight welds on heavy castings and circumferential pipe welds. The specially formulated low hydrogen graphite type flux coating allows for soft welding with the highest joint strength and full machinability. The deposit is very dense, and bonding is good even on difficult to weld cast iron.

Applications
Housings, machinery parts and frames, granulators, heavy pump housing, pressure chambers etc.

Procedures
Maximum machinability and bonding on heavy sections is obtained by pre-heating to 150 degrees. Medium short arc should be maintained. Back-step technique and light peening of the welds is recommended. Before welding the repair area must be machined or ground clean. If ground, remove carborundum particles with an oxidizing flame, searing the area to be welded. Depending on wall thickness, a U or a double U welding preparation must be made. Use a short arc and keep the electrode at a steep angle. Remove slag and peen lightly. Always restrike on the weld deposit and never on the parent metal as this induces thermal shock
