Abstract

The invention discloses a straight pipe welding system. The straight pipe welding system comprises a welding gun, a wiggler, an automatic wire feeding machine and a roller wheel frame, wherein the welding gun is fixedly connected with the wiggler and comprises an electric parameter setting unit which is used for setting electric parameters when a motor of the welding gun works; a straight pipe to be welded is arranged on the roller wheel frame, and the roller wheel frame is used for driving the straight pipe to be welded to rotate; the wiggler is used for driving the welding gun to swing along the welding joint between the to-be-welded end of the straight pipe to be welded and a component to be welded; the wiggler comprises a control unit which is used for controlling the swinging period of the wiggler; and the automatic wire feeding machine is used for feeding a solder wire to a welding gun head, and the welding gun is used for welding the welding joint through the welding gun head. The straight pipe welding system provided by the invention can improve the welding efficiency of the straight pipe, reduce air pores, lower the weld penetration probability, improve the uniformity of the welding joint, and guarantee the welding quality.

Description

technical field [0001] The invention relates to the field of straight pipe welding, in particular to a straight pipe welding system. Background technique [0002] When the automatic welding process is used in the straight pipe welding, due to the uneven control of the welding speed, it is easy to cause the molten pool to crystallize too quickly, and the gas has no time to overflow, resulting in a large number of continuous pores, making the appearance of the weld uneven; The uneven distribution of the seam is easy to weld through; at the same time, it causes stress concentration at the weld, resulting in the defect of low safety of the straight pipe welding interface. The amount of labor spent on dealing with these defects in the prior art often exceeds that of automatic welding, which brings difficulties to automatic welding, and even has to stop automatic welding and use manual electric welding instead. Contents of the invention [0003] The technical problem to be solv...
