The invention discloses a welding and positioning apparatus of a steel pipe flange, relating to an auxiliary welding facility. The middle-upper part of an upright of the positioning apparatus is provided with a lifting telescopic rod which is movably connected with the upright via a grooved pulley; two axially adjustable wheels are arranged at the lower side of the front end of the lifting telescopic rod; a telescopic rod frame is arranged at the upper side of the front part of the lifting telescopic rod, and an adjustable radial wheel is arranged at the lower side of the middle part of a cross rod of the telescopic rod frame; and a welding gun frame is fixed on the telescopic rod frame to form the welding and positioning apparatus of the steel pipe flange. In the invention, a simple mechanical device is adopted to follow up the flange, so that the defects of large out-of-roundness of domestic steel pipes and axial and radial runout generated in the process of rotation are overcome, the welding precision is increased, the deflection of a welding seam is reduced and the welding quality is improved.
Description
technical field [0001] The invention belongs to the technical field of welding. technical background [0002] At present, the welding seam positioning equipment of steel pipe flange welding uses laser positioning, infrared positioning, ultrasonic positioning, and roller positioning, etc. The first three positioning methods need to install corresponding transmitting devices and receiving devices. The positioning accuracy is high, but the equipment is complicated. Purchase, use and maintenance costs are high. The roller positioning device uses inclined rollers to lean against the flange for positioning. If the out-of-roundness and curvature of the steel pipe are relatively large, the positioning accuracy cannot be guaranteed. Although the structure of this equipment is relatively simple, the use and maintenance costs are low. But the positioning accuracy is poor. Contents of the invention [0003] The object of the present invention is to provide a steel pipe flange weldin...
