| Abstract: | According to the standard's requirements, test piece for qualification of welding procedure and for product welding should be carried out various bending test. On the basis of calcuiation and experience, through side-bending test, test piece's extensibility is relative small, and its weld surface after processed is unaffected by the piece's surface quality. So, the side-banding's result is more practice and accurate. |
