【Abstract】 In order to solve the problem of unstable quality, serious deformation and low degree of automation in the welding process of a certain type of product, it was studied that the intelligent welding process and equipment of controlled P-TIG robots. Controlled the heat input by adjusting arc shape, pulse frequency, pulse width ratio, pulse current value and other parameters, so as to control the volume, the depth and performance of the heat affected zone of the molten pool. And with integration measures of the welding robots, laser locating system, weld pool vision collaborative sensing system and other intelligent technology, it was found that the deformation rule of thin-walled cylindrical parts in the process of longitudinal seam welding single-side welding double-sided forming process, the welding deformation of thin-walled steel cylinder was better controlled, and the welding quality was excellent. The welding process had the ability of automatic production, it promoted the development of new quality productivity characterized by high technology, high efficiency and high quality.更多还原
