Special Design for Welding Cast Steel - Z308  Pure nickel cast iron electrode GB / T 10044 EZNi-1 AWS ENi-C1 JIS DFCNi – Tianqiao Detail:

APPLICATIONS:

It is suitable for the welding of thin pieces of cast iron welding and machining surfaces, such as cylinder heads, important gray cast iron engine blocks, gear boxes, and Machine Tool and soon.

CHARACTERISTICS:

THZ308 is pure nickel welding core, strong reduction of graphite type coating iron rod. It can be used in AC and DC dual purpose and is  easy to operate. When welding, it is not necessary for weldment to preheat. It has good crack resistance and processability.

RECAUTIONS:

1. Before welding, the electrodes need to be baked for 1 hour with the temperature of 150±10℃ before using.
2 It can eliminate welding stress and avoid crack by hammering the welding seam.
3. In order to reduce the impurity elements in the base metal penetration weld, narrow white band width, improve crack resistance and processing properties, it should use small current welding in cast iron cold welding.

Welding distortion correction:

For deformation correction in hot state, mechanical correction and hammering are strictly prohibited in the range of blue brittle temperature (300℃~500℃) to avoid brittle cracks.

Pay attention to the following requirements when the flame is locally heated

It is not advisable to repeat heating at the same part to avoid changes in the metallographic structure and mechanical properties of the steel.

Do not cause repeated corrections of tension and compression in the same part.

For hardenable welded parts, watering and rapid cooling are strictly prohibited.

Welding parts that need to be annealed should be rectified before annealing to eliminate internal stress during annealing. During annealing, the welded parts must be placed steadily so as not to deform again.

The flame straightening heating temperature can be 700℃~850℃ (fuchsia), and should not exceed 900℃ (bright red) for low alloy structural steel.
