Abstract

The invention discloses a tailor welding device for a titanium-steel composite plate. The tailor welding device comprises a welding robot, a plasma welding gun, a binocular CCD (charge coupled device) near infrared visual sensing device, a welding parameter acquisition instrument device and an industrial personal computer, wherein the plasma welding gun is fixedly arranged on a small arm flange of the welding robot, the binocular CCD near infrared visual sensing device and the welding parameter acquisition instrument device are connected with the industrial personal computer respectively through signal control wires; the tailor welding device adopts a plasma beam deposition welding method, so the energy is more centralized, heat input is reduced, and the working efficiency of composite plate splicing is remarkably improved; a plasma beam is higher in stability, the one-step forming of composite plate splicing is easily guaranteed, the repair welding caused by defects generated by traditional welding methods is avoided, joint microstructures are more uniform, and the mechanical property is more superior; the tailor welding device adopts the binocular CCD near infrared visual sensing device and the welding parameter acquisition device, so that characteristic parameters of a molten pool can be rapidly extracted, the depth of fusion is accurately controlled, and the requirement of full-penetration tailor welding of the composite plate is realized.

Description

technical field [0001] The invention belongs to the technical field of composite plate welding, in particular to a tailor welding device for titanium-steel composite plates. Background technique [0002] At present, the tailor welding of composite panels mainly adopts manual arc welding, manual TIG welding, manual MIG welding and a small amount of automatic TIG and MIG welding.
