PRODUCTS DESCRIPTION

Nickel-Based Electrodes for Cast Iron

Nickel-based cast iron electrodes for welding cast iron belong to cold welding electrodes for heterogeneous welds. The coating is strongly reducing graphite type, AC and DC dual-purpose, good process performance, and can be welded in all positions. The weld metal has good workability and the ability to withstand plastic deformation. In order to reduce the adverse effect of the hard and brittle structure in the fusion zone on the post-weld processability, so that the white layer is as small as possible, thinner and discontinuous, the cold welding process regulations should be strictly followed during welding.

Pure Nickel Cast Iron Welding Rod

Standard:

Conforms to GB EZNi-1

Comparable to AWS ENi-C1

Description:

Z308 is a cast iron electrode with pure nickel core and strong reducing graphite coating, which can be used for both AC and DC. The arc is stable during welding, the operation is convenient, and the weldment does not need to be preheated. It is an electrode with better comprehensive properties such as crack resistance, machinability, and weld strength among cast iron cold welding electrodes.

Purpose:

It can be used for important gray cast irons at room temperature or slightly preheated (to about 200°C), such as: processing surfaces of thin cast iron parts, welding of cylinder heads, engine blocks, gearboxes, machine tool guide rails, mechanical parts made of cast iron, etc.

Precautions:

1. First remove the oil, sand, water, rust and other dirt from the welding part, and depending on the type of defect, take preparatory measures such as bevelling, cracking stop hole and molten pool shape. 2 If a large gap is to be filled, a layer of surfacing welding should be started from the surroundings first, and then gradually filled to the middle. 3 In order to avoid excessive melting of the base metal and reduce the white layer, during welding, try to use small current, short arc, narrow path, short path, and dispersed segmental welding. The length of each weld bead generally does not exceed 50mm. Continue welding until it is not hot. And hammer the weld immediately after welding to relax the stress and prevent cracks. 4 Before welding, the electrode should be baked at about 150°C for one hour.
