Abstract

The invention discloses a welding device and a welding technology applying a multifunctional fillet welding trolley to horizontal position welding. The welding device applying the multifunctional fillet welding trolley to the horizontal position welding comprises the fillet welding trolley, wherein the fillet welding trolley is arranged on one side of a weldment; a run-on plate and a run-off plate are mounted at the head end and the tail end of the weldment respectively; an angle steel baffle parallel to a welding pass is arranged on the front surface of the weldment; a ceramic pad and a horse plate are arranged on the back surface of the weldment; and a magnet pull handle, a guide wheel arm and a welding gun are arranged on the fillet welding trolley. The welding technology applying the multifunctional fillet welding trolley to the horizontal position welding comprises the following steps of chamfering the weldment to form the welding pass before welding, welding a backing welding layer, and then welding a filling cosmetic welding layer. The device and the technology have the benefits that an application scope is enlarged, the production cost is lowered, the labor intensity is reduced, the operation is easier and more convenient, the trolley for the automatic welding operates more stably, the surface of a welding joint is formed attractively, and is high in flaw detection yield, and the production efficiency can be improved.

Description

technical field [0001] The invention relates to a welding device using a multifunctional fillet welding trolley for horizontal welding. [0002] The invention also relates to a welding process using a multifunctional fillet welding trolley for horizontal welding. Background technique [0003] In the shipbuilding and ocean engineering industry, for the splicing of large steel plates, multifunctional fillet welding trolleys are usually used for automatic CO2 gas welding for long welds in the flat fillet welding position, and automatic horizontal welding is usually used for long welds in the horizontal welding position. The trolley performs automatic CO2 gas welding or directly uses semi-automatic CO2 gas welding. Such a method makes the scope of application of the multifunctional fillet welding trolley too narrow, and the production cost is too high. Moreover, because the automatic horizontal welding trolley is not easy to carry and runs unstable, the weld shape is not beauti...
