Circumferential welding
WebCircumferential weld misalignment can generally be separated into two categories, axial and angular. Exam-ples of each are illustrated in Fig. 1. For axial misalignment, the two most common ways of categorizing it are “hi-lo” misalignment and wall eccen-tricity, with each having their respec-tive application — Fig. 2. WebIn welding thin plates, however, use is made of a flux backing with electromagnetic retainers. Circumferential butt welds are often made with a flux-belt backing as shown in Fig. 8.15. In all these cases, the bed of flux shapes the root run and protects the weld from the harmful effects of the atmospheric gases. 2. Copper Back-up Plate or bar:
