About Crack Repair of A Press Frame-3500 Ton
RA Power Solutionswas approached by a leading automobile manufacturing company based in North India to execute the repair of a damaged main frame body of 3500 Ton Press, supplied, installed, and maintained by a renowned Japanese company. RA Power Solutions team of engineers visited the plant during the shutdown and following was observed.
- The main frame of the 3500 Ton Press, which developed crack was the backbone of the plant as the complete body of the vehicles including doors/bonnet etc were formed on the press.
- The company was asked to disassemble all the parts, adjacent to the area where the crack was developed.
- The crack area of the press was thoroughly cleaned. Paint and red oxide were completely removed by the chemicals.
- The hardness test of the crack area of the press was undertaken.
- The MPI test was done on the crack area where a crack having a horizontal profile measuring 400 MM was observed.
- The crack was through the complete width of the frame plate having thickness of 40 MM.
All the technical parameters including load characteristics of 3500 Ton Press were studied by the RA Power Solutions engineers and it was decided to go ahead with therepair of crack by metal stitchingand metal locking process.

FAQ's of Crack Repair of A Press Frame-3500 Ton:
Q: How is the crack repair performed on the 3500-ton press frame?
A: Crack repair is executed through advanced welding and the addition of reinforcements at critical stress zones. The process includes thorough crack removal, precision welding, application of reinforcing elements, post-weld heat treatment, and a final load test for validation.
Q: What inspection methods are used before and after repair?
A: Both ultrasonic and visual testing are employed to detect and assess cracks before repair, and to verify the integrity of the welds and reinforcements after the repair process is completed.
Q: When should crack repair be conducted on an industrial press frame?
A: Crack repair should be undertaken as soon as any structural flaws are identified during routine maintenance or scheduled inspections, especially in critical stress areas to prevent operational failure.
Q: Where are the repairs targeted within the press frame?
A: Repairs are focused on the critical stress zones of the frame, where cracks are most likely to compromise structural performance and safety.
Q: What is the benefit of post-weld heat treatment in this process?
A: Post-weld heat treatment relieves residual stresses from welding, enhances metallurgical properties, and prevents further cracking, resulting in a more durable and reliable repair.
Q: How does this service extend the life of the press frame?
A: By addressing existing cracks and reinforcing vulnerable zones using advanced techniques, the repair service prolongs the operational life of the frame by 5 to 10 years, even under demanding industrial conditions.
Q: Who provides these crack repair services in India?
A: We are a prominent exporter, manufacturer, service provider, supplier, and trader based in India, specializing in the crack repair of heavy-duty industrial press frames.
