Abstract
The utility model discloses a welding device of a weld seam in a spiral welded steel pipe, which belongs to the welding equipment, in particular to the equipment used for welding the weld seam in thespiral welded steel pipe. The welding device comprises a wire conveying mechanism, a welding gun, a conductive nozzle and a wire conveying wheel, and is characterized in that a welding gun supportingframe and a welding gun fixing and connecting plate in front of the wire conveying mechanism are fixedly connected with the wire conveying mechanism through fixing bolts, the long-distance welding gunis arranged on the welding gun fixing and connecting plate, a welding gun rod is supported at the front end of the welding gun supporting frame, the arc radius of the front end of the welding gun is100 to 150 mm, and conductive copper wires are fixedly arranged on the conductive nozzle and the welding gun rod. Since the turning radius of the front end of the long-distance welding gun is changedand a spring is arranged in the cavity of the welding gun, the utility model ensures the smooth movement of the welding wire in the welding gun, and solves the arc breaking problem. With the inner supporting frame under the welding gun, the utility model prevents the welding gun from shaking, provides the uniform welding arc, and improves the welding quality of the weld seam.
Description
Technical field
The utility model belongs to a kind of welding equipment, especially for the equipment of spiral welded steel pipe inside weld welding.
Background technology
In the spiral welded steel pipe production line, use submerged-arc welding to weld outside weld and inside weld respectively, the welder that uses of inside weld wherein, the welding gun of one elbow radian near 90 degree is housed in the wire feeder front, welding wire in the welding gun is approaching right angle mode lower wire feeding hose, resistance is big, and following silk is not smooth, easily causes current interruption, fault rate is big, influences production efficiency; Former welding gun bulkiness, the space of steel pipe own is narrow and small, is difficult for the angle of Butt welding gun and the position of solder joint and adjusts; Owing to the long no bracing frame of welding gun length, instability during welding gun work causes voltage pulsation big, the welding quality instability in the welding process.
The utility model content
In order to overcome the deficiency that existing inside weld welder send welding wire to have some setbacks, the purpose of this utility model provides a kind of spiral welded steel pipe inside weld welder, and this spiral welded steel pipe inside weld welder wire feed is smooth and easy, smooth welded seam.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of spiral welded steel pipe inside weld welder, comprise wire feeder, welding gun, ignition tip, wire feed rolls, it is characterized in that: the welding gun bracing frame, the welding gun fixed connecting plate that are positioned at the wire feeder front are fixedly connected on both on the wire feeder by set bolt, length is installed on the welding gun fixed connecting plate apart from welding gun, the welding gun supporting framing front end is supporting the welding gun bar, welding gun front end arc radius is 100-150mm, and conducting copper is fixed on ignition tip and the welding gun bar.
Described length is equipped with welding wire 10 and spring 9 apart from the welding gun inner chamber, and spring inside diameter is greater than gage of wire 3-8mm.
The beneficial effects of the utility model are owing to changed long radius of turn apart from the welding gun front end, and be provided with spring at the welding gun inner chamber, thereby guaranteed smooth and easy move of welding wire in welding gun, solved the phenomenon that occurs current interruption easily, bracing frame has been avoided the shake of welding gun in installing under welding gun, makes welding arc evenly improve the weld seam welding quality.
