Abstract

The invention relates to the technical field of railway vehicle welding and discloses a double-machine cooperation automatic welding method for a railway vehicle cross beam. The double-machine cooperation automatic welding method can comprise the following steps of completing structural simulation of the cross beam through a welding sample plate, and determining the specific forms of welding seamsof the sample plate according to the welding angles and the positions of the welding seams, wherein the welding seams of the sample plate comprise pretreatment layers, filling layers and cover surface layers which are welded from inside to outside, the overall welding operation follows the rules that ship type position balanced welding is conducted, the filling layers are welded in the first place, and then the cover surface layers are welded, and the welding sequence of front face welding, back face welding, front face welding, vertical welding and vertical welding is adopted; determining the welding currents, the welding voltages, the welding speeds and the wire feeding speeds for the pretreatment layers, the filling layers and the cover surface layers; and controlling the pressure welding quality of each welding pass and overlaying joint quality. The invention further discloses a double-machine cooperation automatic welding system for the railway vehicle cross beam. By means of thedouble-machine cooperation automatic welding method and system for the railway vehicle cross beam, welding efficiency of the cross beam can be improved, and welding deformation is effectively controlled.

Description

technical field [0001] The invention relates to the technical field of rail vehicle welding, in particular to a method and system for a rail vehicle crossbeam double-machine cooperative automatic welding method. Background technique [0002] With the increase in orders and the limitation of the plant area, it is required to increase the utilization rate of the unit plant area under the condition that the original plant area remains unchanged, so as to reach the production capacity of 3 vehicles per day, which requires the improvement without increasing the floor area of ​​the robot. Efficiency. The existing beam robot welding improves welding efficiency through double-wire welding. Double-wire welding has high requirements for beam structure and welding position. For subway beams, due to structural differences, there are a large number of 50mm steel plates and beam steel tubes. Welding seam, this type of welding seam is short and the welding space is small. If twin wire weld...
