Steel plate welding device with dehumidification function

Abstract

The invention discloses a steel plate welding device with a dehumidification function. The device structurally comprises a comprehensive welding unit, a device body, a connecting block, a welding gun,a connecting pipe, an arranging and butt-joint supporting frame, a base and supporting legs. The comprehensive welding unit is mounted in the device body, the bottom end of the connecting block penetrates through the top of the device body and is connected into the comprehensive welding unit, the right end of the welding gun is perpendicular to and connected with the left end of the top of the connecting block, the right end of the connecting pipe is connected into the comprehensive welding unit through the connecting block, the bottom of the arranging and butt-joint supporting frame is perpendicular to and connected with the top of the base, and the supporting legs are sequentially connected to form a rectangular structure and arranged at the bottom of the device body. According to the steel plate welding device, the moving track of the welding gun is fixed, thus, the welding stability can be improved, and accordingly, the welding precision degree is increased; and meanwhile, a welding position and positions within certain ranges on the two sides of the welding position can be baked and dehumidified through the device, thus, the welding firm degree can be increased, and meanwhile, the practical value of the device is increased.

Description

technical field [0001] The invention relates to the technical field of welding treatment, in particular to a steel plate welding device with the function of removing moisture. Background technique [0002] In shipbuilding enterprises, it is often encountered that dissimilar steels with different linear expansion coefficients are welded together, such as welding low-alloy steel plates with marine steel plates. For the welding of low-alloy steel and marine steel plates, E5015 electrodes have been used in the past. Electrode arc welding, due to the characteristics of the material itself, manual arc welding must be used during welding, the work efficiency is low, the welding operation is difficult, and the welder's labor intensity is high; because the heat input of E5015 electrode arc welding is large, and the low alloy steel plate has strength High linear expansion coefficient, so it is easy to produce welding deformation during welding, especially when welding thin plates, the...

[0002] In shipbuilding enterprises, it is often encountered that dissimilar steels with different linear expansion coefficients are welded together, such as welding low-alloy steel plates with marine steel plates. For the welding of low-alloy steel and marine steel plates, E5015 electrodes have been used in the past. Electrode arc welding, due to the characteristics of the material itself, manual arc welding must be used during welding, the work efficiency is low, the welding operation is difficult, and the welder's labor intensity is high; because the heat input of E5015 electrode arc welding is large, and the low alloy steel plate has strength High linear expansion coefficient, so it is easy to produce welding deformation during welding, especially when welding thin plates, there will be obvious deflection deformation, and it is difficult to correct the deformation after welding; During electrode arc welding, the overall welding quality is difficult to guarantee

[0003] At present, the welding device for low-alloy steel plate and marine steel plate does not bake and dehumidify the welding part and a certain range on both sides, which will reduce the firmness of the welding and reduce the practical value of the equipment
