Defects in the drawn wire/rod can be either due to the defects in the starting material (seams, slivers and pipe) or can be introduced by the deformation process. Typical defects in a drawn wire/rod are centre cracking. The defect centre burst or cracking (cupping) occurs for low die angles at low reductions.steel pipes are manufactured by which weldingSSAW Steel Pipe Manufacturing Process Seamless steel pipe is manufactured by the round steel billet, through hot rolling, cold rolling or cold drawn processes, no seam on the pipe body.
