Techniques for Automatic Submerged Arc Welding

Welding on a permanent steel backup plate, as shown in Fig. 8.18, like welding on a smooth copper backing, is employed when there is no off-set between the edges. The gap between the prepared edges should be 0-5 to 1 mm. With larger gap the molten metal may flow between the edges and the back-up plate, and thereby spoil the shape of the weld.Submerged Arc WeldingSubmerged Arc Welding: A discussion of the welding process and how welding parameters affect the chemistry ofCorrosion Resistant 20mnmob steel plate Submerged arc welding heat of the arc melts the electrode and base plate to form the weld bead.
