Cast Iron Welding Rod Z308

I. Basic Product Information

II. Product Features and Advantages

1. Excellent Welding Performance

High Crack Resistance: The typical nickel content of the deposited metal reaches 94% (standard requirement ≥90%), which greatly improves the toughness of the weld and effectively avoids cracking problems that are prone to occur in cast iron welding.

Superior Machinability: The weld metal has low impurity content (S≤0.004%, Fe≤0.021%). After repair, it can be directly subjected to subsequent processing such as cutting and grinding without additional treatment.

Low Base Metal Penetration: Controlling the current during cold welding can reduce the penetration of impurities from the base metal into the weld and narrow the width of the fusion zone, further ensuring welding quality.

2. Flexible Packaging Solutions

Standard Packaging:

Inner Layer: 5kgs/PVC Box (Moisture-proof and Dust-proof);

Middle Layer: 4 PVC Boxes/Carton (20kgs per carton);

Outer Layer: 50 Cartons/Pallet (1 ton per pallet);

Customization Service: Packaging specifications can be adjusted according to customer needs to adapt to different scenarios such as small-batch trial and large-batch storage.

3. Efficient Delivery Guarantee

Delivery Cycle: Regular in-stock products can be prepared within 8-25 days, meeting the needs of emergency maintenance and bulk procurement.

Delivery Terms: Supports various international trade terms such as CIF, CNF, FOB, and EXW, flexibly adapting to global logistics solutions.

IV. Application Scenarios

The Z308 cast iron welding electrode is specially designed for the repair of cast iron components, with core application fields including:

Repair of thin-walled cast iron parts (such as cast iron valves and small pump bodies);

Repair of cast iron machining surfaces (such as machine tool guideways and mold positioning surfaces);

Maintenance of important gray cast iron parts (such as engine gearboxes, heavy machine tool beds, machining tools, etc.).

V. Welding Operation Precautions

Pre-welding Baking: Welding electrodes must be baked at a temperature of 80-120℃ for 1 hour before use to remove moisture from the coating and prevent porosity in the weld.

Post-welding Treatment: After welding, the weld seam should be hammered to release the stress in the welding area and fundamentally avoid cracking.

Current Control: Avoid using high current when cold welding cast iron to reduce the penetration of impurities from the base metal and ensure the crack resistance and machinability of the weld.
