9. Replacement Materials

I. Advantages of Cold Welding Machines:

High melting strength: The repaired area can be machined, filed, etc.

2. High repair accuracy: Uses thin patch materials for repair, maintaining the original datum surface without excess weld material, making it easy for later shaping.

3. Wide Application Range: Suitable for repairing parts made of various metals, excluding materials with low resistivity such as copper and aluminum.

4. Minimal substrate damage: Small hot spots, preventing substrate from annealing and deforming.

5. Easy electrical connection: Equipped with a strong magnetic connector, electrical connection can be easily achieved for workpieces of any size.

 

Section II: Unique Advantages of the YJXB-3 Model:

The new repair machine has greater power, a smaller size, and lighter weight (the main unit weighs only 8Kg) compared to the older model.

2. Microcomputer control, intelligently adjusts to different thicknesses of filler materials, various workpieces, and different welding nozzle sizes.

Power distribution is more reasonable, with digital display for clearer and more convenient operation.

3. Switching power supply technology ensures stable high-power output even when voltage fluctuates within ±20% of 220V, guaranteeing welding quality.

4. A dedicated precision welding mode and precision welding nozzle are set up to provide more support for delicate operations.

5. Matching suitable accessories, providing solutions for single-sided bipolar welding in the hardware industry.

 

III. Typical Applications:

Molding Industry: Repair services for various injection molds, extrusion molds, rubber molds, die casting molds, and metal molds

2. Machinery Industry: Repair of various machinery components, such as guides, shafts, crankshafts, hydraulic rods, etc.

3. Foundry Industry: Sand holes, blow holes, machining tolerance overruns, etc., in various castings (cast steel, cast iron, stainless steel, etc.)

4. Printing & Textile Industry: roller repair for anilox rolls, roller mills, mirror rolls, printing machine cylinders, etc.

5. Hardware Industry: Pad Welding Sheets

 

Special Note: Please differentiate between the maximum single-layer thickness and the maximum single-point thickness, the maximum welding thickness, and the reliable welding thickness.


1. Single Layer vs. Single Spot: The principle of cold-weld repair is similar to resistance welding. When there is only one welding point, since there is no power分流 around the welding point, the output power is concentrated, allowing for thicker welding. However, for general repair work, it is definitely necessary to repair a surface. When repairing a surface, there are other welding points around each welding point (except for one) that分流 the output power, necessitating a reduction in the thickness that can be reliably welded. Generally, when determining the power of a repair machine, it is recommended to use the reliable welding thickness of a single layer as a standard. All the data on our company's manuals are for single-layer reliable welding.


2. Maximum Welding Thickness & Reliable Welding Thickness Limit: Simply welding material on does not guarantee a secure weld. As a repair machine, the material being welded must be fully melted into the workpiece (i.e., a reliable weld), otherwise, the patch material is prone to falling off during later processing and use. The data on our manual are all for single-layer reliable welding.

Some materials (such as stainless steel) have special compositions, which may allow for a higher maximum reliable welding thickness than standard steel. Please conduct repeated tests for specific use, or consult with our technical staff.
