Abstract

The invention discloses a welding method for elevation welding of a medium-thickness steel plate, which is characterized in that trolleys are simultaneously arranged on two sides of a vertical plate for welding, and layered welding is carried out, so that a bottoming layer is a whole; two welding guns on the same side are used for filling a layer, and separated welding is carried out on a third filling layer, so that welding materials are saved, the welding speed is increased, meanwhile, the welding quality is higher, and the operation is simple, convenient and easy to master.

Description

technical field [0001] The invention belongs to the technical field of welding, and in particular relates to a welding method for elevation welding of medium-thick steel plates. Background technique [0002] Overhead welding is welding in which the welding position is below the level. Overhead welding is the most difficult of the four basic welding positions. Since the position of the molten pool is below the weldment, the gravity of the molten drop metal of the welding wire will hinder the excessive droplet, and the metal in the molten pool will also fall under the action of its own gravity. The larger the volume of the molten pool, the higher the temperature, and the smaller the surface tension of the molten pool. During overhead welding, the back of the weld is prone to depression, and the front weld bead has weld bead, which makes it difficult to form the weld bead. [0003] Traditional overhead welding, overhead welding requires high welding technology, difficult oper...
