용접 오버레이 레이어가 기본 재료에서 벗겨지는 이유?

그만큼 용접 오버레이 레이어 is a special alloy layer applied to repair worn or cracked surfaces. 기계 제조 및 수리에 일반적으로 사용됩니다. 하지만, 용접 공정이 올바르게 처리되지 않은 경우, the overlay may not bond well to the base material. This can cause the surface to peel.

Below are the main causes of this issue and the recommended solutions.

1. Incorrect Material Selection

• 원인: Inappropriate choice of materials.

• 해결책: Suitable primer 그리고 transition materials should be selected.

2. Excessive Hard Layer Thickness

• 원인: A thick hard layer leads to poor 충격 저항.

• 해결책: The thickness of the hard layer should be reduced, 또는 impact-resistant materials 사용해야한다.

3. High Residual Welding Stress

• 원인: Excess stress remains in the weld area after welding.

• 해결책: 사용 예열, slow cooling, tempering, 또는 multi-step stress relief to reduce stress.

4. Workpiece Stress Exceeds Bond Strength

• 원인: During use, 그만큼 peak stress on the workpiece is too high.

• 해결책: 그만큼 bonding hardness should be increased and the peak stress should be reduced.

5. Poor Welding Process

• 원인: Improper welding process can lead to loss of hardness in the overlay.

• 해결책: 그만큼 welding method should be improved to maintain the quality of the weld.

요약

Weld overlay is a 비용 효율적 그리고 efficient method for surface repair. It is widely used in many industries. To ensure the cladding layer works well, the method should:

• Minimize base material dilution

• 보장하다 high deposition efficiency

• Produce a durable and well-bonded overlay

High-quality and low-dilution cladding techniques are strongly recommended.
