Webwelded joint. Macroscopic and microscopic examinations were conducted on both sides of the welded joint, on both, old and new material. By visual and radiographic examination welded samples were characterized as acceptable. The above Figure 2 clearly shows the parts of the welded joint: base metal-BM, heat affected zone- WebThe main standardized test method for determining the long-term performance of welded PE specimens is the tensile creep test according to EN 12814-3 or DVS 2203-4. This is basically a stress rupture test in which dumb-bell specimens are subjected to a constant load at elevated temperature (normally 80°C) and the time to failure is recorded. nor hafizah uthm
