In the process of ERW steel pipe, welding quality of welded seam can be achieved by the appearance like welded seam shape, surface condition and mechanical properties of welded seam inspection and metallographic analysis to decide. In the process of production, welded seam shape of bending form and surface condition can provide the reference for the welding process adjustment. Mechanical properties testing are generally carried out in accordance with the standards or customers' special requirements.
