According to the standard's requirements, testpiece for qualification of welding procedure and for product welding should be carried out various bendingtest.
焊接工艺评定试板和产品焊接试板,按标准要求都要进行弯曲试验。

A bending of the test-piece should be reduced to a difference between the profile at the measurement and the initial profile which was determined before bending.
试件的挠度应减小到观测时的轮廓与弯曲前已确定了的初始轮廓之间的差值。

Thus continuing the regular measurements of the bending curves of the test-piece, one could construct a creep curve.
