Embodiment 1

[0020] like figure 1 , figure 2 As shown, a ship thin plate welding device includes a welding torch 1 and a welding frame 2, the welding torch 1 is fixed on the welding frame 2, and a synchronous heating gun 3 capable of spraying flame is also fixed on the welding frame 2 for synchronous heating The torch 3 and the welding torch 1 are placed in an angle structure, and the synchronous heating torch 3 intersects with the extension line of the torch head of the torch 1 at a point, and a thin plate channel is left between the synchronous heating torch 3 and the torch 1 . Synchronous heating gun 3 and welding gun 1 are controlled by the same switch button. The flame temperature of the synchronous heating gun 3 is lower than the temperature when the torch 1 is energized for welding, and the synchronous heating gun 3 is kept at a distance from the thin plate, so the synchronous heating gun 3 will not melt the thin plate. The welding frame 2 includes a support frame 4, a pallet 5 a...

Embodiment 2

[0023] Welding torch shifting rail 6 is channel steel, and the welding torch place end of gun frame 7 is fixedly provided with the roller that matches with the groove of channel steel, and roller rolling is embedded in the groove of channel steel. All the other are with embodiment 1.

Abstract

The invention discloses a welding device for a ship thin plate. The welding device for the ship thin plate comprises a welding gun and a welding mounting frame. The welding gun is fixed to the weldingmounting frame, a synchronous heating gun is further fixed to the welding mounting frame, the synchronous heating gun and the welding gun are placed in an angle structure, the synchronous heating gunintersects with an extension line of a welding gun head, and a thin plate channel is reserved between the synchronous heating gun and the welding gun. When the thin plate welding is carried out by using the welding device of the ship thin plate, a thin plate is placed in the thin plate channel, the welding gun and the synchronous heating gun are separately arranged on the two surfaces of the thinplate, when the welding gun performs welding on the surface of the thin plate, meanwhile, the synchronous heating gun performs heating in a region corresponding to the welding position on the other surface, and the single surface heating of the thin plate is avoided; and the temperature difference between the two surfaces of the thin plate can be reduced, the bending of the two surfaces of the thin plate due to the uneven heat expansion degree and the like is reduced, so that the deformation degree of the thin plate welding is controlled.

Description

technical field [0001] The present invention relates to a welding device, more particularly, it relates to a ship thin plate welding device. Background technique [0002] Many structures and facilities on ships are welded with thin plates. As we all know, the thickness of the thin plates is small and the bending strength is poor. Due to the heat on one side during welding, there is a time difference between the temperature rise of the two sides of the thin plates, resulting in the bending of the two sides of the thin plates due to the different degrees of heating and stretching. Therefore, the welding of thin plates has the problem of easy deformation, which increases the difficulty of welding operations, seriously affects the accuracy of welding, and ultimately adversely affects the performance and aesthetics of ship structures. Therefore, it is necessary to improve the existing thin plate welding process and equipment. The invention patent with the publication number CN10...
