Problems solved by technology

Traditional manual argon tungsten arc welding is used to weld the isolation pad. Due to the thin stainless steel plate, large welding volume, concentrated weld seam, and large heat input, the welding deformation of the stainless steel pool module is large. Once the deformation is out of tolerance, the correction is very troublesome.
At the same time, manual argon tungsten arc welding is highly dependent on the welder's skill level, high training cost, low welding efficiency, high production cost, and is easily affected by the welder's own state, resulting in unstable welding quality

Embodiment 1

[0046] Such as Figure 1~13 As shown, a large-scale stainless steel pool module isolation pad welding device includes a gantry resistance welding torch frame and an automatic feeding device. The automatic feeding device is arranged on one side of the gantry resistance welding torch frame. On the welding torch frame 6, the welding torch frame 6 is slidingly arranged on the horizontal frame 401 of the gantry horizontal sliding frame 4, the two ends of the horizontal frame 401 are slidably connected with the gantry vertical frame 404, and the two ends of the gantry vertical frame 404 are arranged on the gantry support frame 7, The structure of the automatic feeding device is as follows: comprising a retrieving horizontal frame 11, the retrieving horizontal frame 11 is slidably connected with the vertical sliding frame 12, the vertical sliding frame 12 is slidably connected with the longitudinal sliding frame 13, and the two ends of the vertical sliding frame 13 are arranged on the...

Embodiment 2

[0061] Further description in conjunction with embodiment 1, as Figure 1-13 As shown, the spacers 2 are neatly stacked on the discharge rack 9, and the discharge rack 9 is placed on one side of the retrieving support frame 8, and is kept vertical to the retrieving support frame 8.

[0062] The reclaiming horizontal frame 11 slides to the top of the discharge rack 9 driven by the first motor 1102, and the vertical sliding frame 12 is driven down by the second motor 1202, so that the reclaiming horizontal frame 11 is lowered to the discharging position of the discharge rack 9, The third motor 1304 is driven to slide left and right to the slide frame 12, so that the reclaiming horizontal frame 11 can adjust its position left and right.

[0063] The suction nozzle 14 of the reclaiming horizontal frame 11 is adjusted to the suction point 202 of the isolation pad 2, the air pump is turned on, and the suction nozzle 14 sucks the isolation pad 2.

[0064] The take-up horizontal fram...

Abstract

The invention provides a large-scale stainless steel pool module isolation pad welding device and its welding method. The automatic feeding device is arranged on one side of the gantry resistance welding gun frame, a plurality of welding torches are arranged on the welding torch frame, and the welding torch frame is slidably arranged on the gantry horizontal sliding frame On the horizontal frame, the two ends of the horizontal frame are slidably connected with the gantry vertical frame, and the two ends of the gantry vertical frame are set on the gantry support frame, the reclaiming horizontal frame is slidably connected with the vertical sliding frame, and the vertical sliding frame is slidably connected with the longitudinal sliding frame , the two ends of the longitudinal sliding frame are set on the retrieving support frame, and there are multiple retrieving devices on the retrieving horizontal frame. It is inconvenient to change the four directions during welding, and the dense arrangement of pads is limited in operation. As long as the welding parameters are set and the pad positioning is set, the gantry resistance welding machine can realize automatic welding, and the welding process is stable and the output is stable.

Description

technical field [0001] The invention relates to the field of welding of isolation pads of pool modules, in particular to a welding device and a welding method for isolation pads of large stainless steel pool modules. Background technique [0002] At present, large-scale stainless steel pools in the nuclear industry implement a modular construction model. Module units are prefabricated in the workshop and installed on site to improve the welding quality of stainless steel pools and speed up the construction progress. In the process of manufacturing stainless steel pool modules, it is often necessary to weld a large number of isolation pads on the cladding panels (about 6m-8m in length, about 1m-2m in width, and about 2mm-6mm in thickness) (see figure 1 ). There are two main functions of the isolation block: 1) to prevent the stainless steel cladding from being polluted by ferrite due to direct welding between the stainless steel cladding and the carbon steel back rib; 2) to ...
