Problems solved by technology
[0004] The technical problem to be solved by the present invention is to provide a one-time forming welding device for butt jointing of thin plates in view of the above disadvantages. Using this device for welding not only solves the problem of arc heat concentration, but also improves the problem of large welding heat input and reduces welding. The restraint stress generated at the same time makes the weld be formed at one time. The cost of welding materials is only 50% of the original process. The surface of the weld is beautiful and saves a lot of repairing and grinding work. %above

The invention relates to a one-time forming welding device for butt joint of sheets. The one-time forming welding device for butt joint of sheets comprises an operation table, wherein a steel plate supporting seat, a liner supporting seat, an end tab fixing assembly and an arc welding machine assembly are arranged on the operation table. The one-time forming welding device resolves the problem of electric arc heat concentration and the problem of large welding heat input when used for welding, reduces the restrain stress generated in the welding process and enables the weld joint to be formed at a time. The welding materials are only half that of an original process. The surface of the weld joint is beautiful, so that much repairing and grinding work is saved. The internal welding quality is controlled to a limited extent. The welding pass rate can be controlled to be above 99.89 percent.
Description
technical field [0001] The invention relates to a welding device, in particular to a one-shot forming welding device for butt jointing of thin plates. Background technique [0002] With the rapid development of the shipbuilding industry in recent years, welding technology has also been continuously improved and perfected. Since manual welding in the 1960s has developed for more than half a century, shipbuilding companies have widely promoted excellent welding forms and processes such as CO2 gas shielded welding, submerged arc welding, vertical active welding, argon arc welding, and robotic arm welding. But this is only for the welding of medium-thick plates above 8 mm, and there is no effective welding method for automatic welding of plates below 5 mm. [0003] With the continuous update of the concept of "green and environmental protection" in the international shipbuilding industry, the choice of ship steel plate thickness is more and more inclined to meet the minimum pla...
