... in 12.5 mm thick ASTM A285, grade B, steel plate. One joint was welded using the semiautomatic submerged arc process with one pass on each side. A second joint was welded manually by the shielded metal arc process using E6010 welding rod and four passes on each side. The silicon content of the shielded...

.... Circumferential welding was done by the submerged arc process, using preheating at 200 °C (390 °F). Each subassembly was stress relieved by being heated to 620 to 660 °C (1150 to 1220 °F) for 6 h. Final joining of the three subassemblies followed the same welding procedures except that localized heating...

... with a preheat of 65 °C (150 °F), with the heat applied only on the outside wall at point B. The weld was deposited using a single-head submerged arc process, and the failure occurred when 32 mm (1.25 in.) of weld depth had been laid. Sections through the failure revealed that the cracking had initiated...
