Post Weld Stage
After carrying out the welding, visual check and Dye Penetrate check is carried out by us. Radiography is carried out by competent agencies hired by us.
For Non-Destructive testing such as Ultrasonic testing/Radiography of Weld Joints/Hardness survey/Magnetic Particle Test, competent agencies are hired to carry out the job in presence of third party inspector/client's inspector (if desired).
Cases where Post-Weld Heat Treatment is required, the material is sent to outside agency for carrying out Heat Treatment.
Final Hydro-test
Final Hydro-test is carried out, after all the above stages are cleared. For carrying out the hydro-test we have
