Abstract

The invention discloses a special machine for welding a pipeline with small pipe diameter. The special machine comprises a traveling trolley, a welding power source, a cross beam, a moveable stand column, a fixed stand column, a welding machine head, a flux conveying recovering device, a weld joint automatic tracking device and a programmable controller, wherein the welding power source and the moveable stand column are both arranged on the traveling trolley; the flux conveying recovering device is arranged on the rear end of the cross beam; a cross beam hoisting mechanism is arranged on the moveable stand column; the rear part of the cross beam is connected to the cross beam hoisting mechanism; the fixed stand column is arranged on the front part of the cross beam; the fixed stand columnis provided with a micro-adjusting mechanism for adjusting the up and down positions of the cross beam; the front part of the cross beam is supported on the micro-adjusting mechanism; the welding machine head is mounted on the front end of the cross beam; the rear part of the cross beam is provided with a rear wire feeder; a front wire feeder is mounted in the welding machine head; and a welding gun is mounted on the front wire feeder. By utilizing the special machine provided by the invention, the feeding speed is kept accurate and stable, the hanging state of the cross beam is avoided, the intensity of the cross beam is increased, the welding quality is ensured, and the degree of automation is high.

Description

technical field [0001] The invention relates to a pipeline welding equipment for welding the inner and outer longitudinal seams and circular seams of small-diameter pipelines used in the pipeline production industry, and belongs to the technical field of pipeline welding. Background technique [0002] At present, large-diameter pipes can basically realize all-position automatic welding. The realization process uses the cross manipulator and the roller frame to cooperate with each other and the manual welding of the welding trolley to realize the welding of the inner and outer longitudinal seams and circular seams of large-diameter pipes. However, due to the relatively large volume of the manipulator head and the welding trolley, these two methods cannot meet the requirements for the welding of small-diameter pipes. Therefore, the existing special-purpose pipe welding machines are not suitable for small-diameter pipes. Welding of longitudinal seam and inner ring seam. Conte...
