Embodiment 1

[0035] With 60mm thick steel plate and single-sided V-shaped groove, the welding is completed in two steps. The size of the slider body and the welding assembly method are as follows: Figure 5 shown. The steel plates on both sides are grooved at 10° respectively, and the assembly gap at the root is 8mm. The two sides of the slider body are each processed with a 10° inclination angle. In order to ensure that the welding seam is completed in two steps and the slider body slides smoothly inside the groove, according to the calculation of the thickness of the plate and the angle of the groove, the size of the slider body extending into the direction of the thickness of the plate can be set to 28mm, and the maximum dimension in the direction perpendicular to the thickness of the plate is 26mm. The diameter of the air outlet is 14mm, the arc radius (R1) of the molding surface of the slider body is 10mm, and the transition between the two sides of the slider is 4mm rounded (R2).

Embodiment 2

[0037] With 100mm thick steel plate and double-sided X-shaped groove, the welding is completed in four steps. The size of the slider body and the welding assembly method are as follows: Figure 6 shown. The steel plates on both sides are respectively opened with 12° double-sided symmetrical grooves, and the root assembly gap is 8mm. In order to cooperate with the grooves on both sides, the two sides of the slider body are each processed with a 12° inclination angle. In order to ensure that the welding seam is completed in two steps and the slider body slides smoothly inside the groove, according to the calculation of the plate thickness and the groove angle, the size of the slider body extending into the plate thickness direction can be set to 23mm, and the maximum dimension in the vertical direction of the plate thickness is 26mm. The diameter of the air outlet is 14mm, the arc radius (R1) of the molding surface of the slider body is 10mm, and the transition between the two ...

Embodiment 3

[0039] With 100mm thick steel plate and double-sided K-shaped groove, the welding is completed in four steps. The size of the slider body and the welding assembly method are as follows: Figure 7 shown. The steel plate on one side is not beveled, and the steel plate on the other side is beveled with 15° double-sided symmetry, and the root assembly gap is 8mm. In order to cooperate with the grooves on both sides, one side of the slider body has no inclination angle, and the other side has a 15° inclination angle. In order to ensure that the welding seam is completed in two steps and the slider body slides smoothly inside the groove, according to the calculation of the plate thickness and the groove angle, the size of the slider body extending into the plate thickness direction can be set to 23mm, and the maximum dimension in the vertical direction of the plate thickness is 19mm. The diameter of the air outlet is 10mm, the arc radius (R1) of the molding surface of the slider bo...

Abstract

A water-cooled slider device for gas-electric vertical welding of thick plates, including a slider body used to extend into the inner side of the welding groove. The slider body is provided with two sliding sides, and the two sliding sides can be close to each other. On the vertical side wall of a section of welding groove, one-sided groove can be made for steel plates with a thickness of less than 60mm, and the welding can be completed in two steps, and double-sided grooves can be made for steel plates with a thickness of 60mm to 100mm, and welding can be completed in four steps, expanding the scope of single-sided welding. The thickness range of wire gas electric vertical welding is applicable. There is a gap between the two sliding sides and the vertical side wall of the welding groove close to it. The side of the slider body extending into the welding groove is provided with a section protruding outward. The forming arc surface, the forming arc surface and the two sliding sides are connected smoothly through a transition arc surface respectively, which is conducive to the flow of slag during the welding process and ensures good fusion of the side wall of the root bead. The structure is simple and easy to use. , without increasing the welding heat input, it can improve the welding efficiency and the comprehensive performance of welding joints of thick plate gas-electric vertical welding.

Description

technical field [0001] The invention relates to the field of water-cooled sliders for gas-electric vertical welding, in particular to a water-cooled slider device for gas-electric vertical welding of thick plates. Background technique [0002] Gas-electric vertical welding is to use sliders, liners, etc. to form the molten weld metal to realize the welding of steel plates at the vertical welding position. Usually, the back liner is installed on the back of the base metal groove, and the water-cooled slider is installed on the front of the groove. During welding, the slider moves with the welding torch, and a closed welding space is formed between the back liner, the front slider, and the steel plates on both sides, which realizes the high-efficiency welding method of one-time welding of steel plates. It has been used in ships, marine engineering, oil storage tanks, etc. Widely used in equipment construction. With the development of large-scale structures such as ships and o...
