Metal welding forming system and metal welding forming method based on CMT (cold metal transition)

Abstract

The invention discloses a metal welding forming system based on CMT (cold metal transition). The metal welding forming system comprises a welding industrial personal computer, wherein the welding industrial personal computer is connected with an operation panel. The invention also discloses a metal welding forming method based on the CMT. The metal welding forming method comprises the following steps of putting a processed part, analyzing the shape of the processed metal by the CMT welding system, encoding by an inference engine to set a working track, welding by a welding mechanism along the track, and comparing and straightening in the welding process. The metal welding forming system and the metal welding forming method have the advantages that an image collection card and an optical visual sensor are used for inputting the to-be-welded shape of the metal into the industrial personal computer, database analysis is performed by the CMT welding forming system in the industrial personal computer, a track forming analysis code is encoded through the inference engine, and the welding of the welding mechanism is controlled, so that the shape of the welding metal meets the actual requirements; the forward delivery and back-drawing of a welding wire are controlled by a wire pushing device and a servo wire drawing device in the welding mechanism, so that the closed-loop cold and heat control function is realized.

Description

technical field [0001] The invention relates to the field of welding forming technology, in particular to a CMT-based metal welding forming system and method. Background technique [0002] Metal welding rapid prototyping technology is a rapid prototyping technology that combines metal welding technology and rapid prototyping discrete accumulation principle. The 3D CAD solid model of the target part is obtained through 3D solid scanning or direct modeling, and the model is pressed along a certain coordinate direction. A certain thickness is sliced ​​in layers, and then the metal wire is melted by the welding arc, and each thin layer is formed according to the established forming path, and the layers are accumulated to form an advanced manufacturing technology of three-dimensional solid parts. Compared with the current rapid prototyping technology, metal welding rapid prototyping technology has the advantages of low manufacturing cost, high production efficiency, flexible manu...
