Welding Repair Service for Cracked Press Frames

Revitalize Structure — Stabilize Operation — Extend Equipment Lifespan

Frame Cracks: A Silent Threat to Production

A press frame operates continuously under immense pressure and vibration. Over time, material fatigue or overloads can cause structural cracks.

If not addressed promptly, these cracks will expand, leading to instability, reduced precision, and potentially catastrophic failure of the machine's structure, jeopardizing production safety.

The Solution: Advanced Technical Welding Repair

With a team of engineers who deeply understand machine structures, PRESTEC provides a welding repair service under a strictly controlled process, not only fixing the crack but also reinforcing and extending your equipment's lifespan.

Our Welding Repair Process at PRESTEC

1. Survey & Inspection

Surveying, measuring, and analyzing the crack using specialized equipment (ultrasonic, magnetic particle testing, etc.).

2. Surface Preparation

Machining to clean the cracked area and creating a weld groove (V, X, or U-groove bevel) according to technical standards.

3. Welding Material Selection

Selecting welding rods or wires with mechanical properties suitable for the press frame material (cast iron, alloy steel, etc.).

4. Welding & Stress Relief

Performing multi-layer welding combined with heat treatment and deformation control techniques to eliminate residual post-weld stress.

5. Post-Weld Machining & Inspection

Remachining the surface, ensuring flatness, and re-verifying the machine's geometric accuracy.

6. Reporting & Handover

Providing comprehensive pre- and post-work technical reports, followed by acceptance testing and handover.

More Than Just a Weld

"Each repair weld is not simply patching a crack; it is an engineering process that demands a deep understanding of structural mechanics, materials, precision engineering, and long-term operational safety. At PRESTEC, structural restoration is our highest commitment to our client's assets and production safety."
