Problems solved by technology

[0002] Heat exchange equipment is divided into heaters, coolers, evaporators and condensers. In the production process of heat exchange equipment, submerged arc welding of pipes is indispensable, and submerged arc welding is a kind of arc burning under the flux layer. The method of welding produces extremely high heat during the submerged arc welding process of the pipe, and the heat exchange pipe is a good conductor of heat. Excessively high temperature will easily affect the welding quality of the submerged arc welding and the quality of the pipe. At the same time, the existing technology Submerged arc welding tooling cannot be applied to the arc-shaped outer surface of the pipe, resulting in unstable installation and affecting the arc welding process

Abstract

The invention relates to a tool special for submerged-arc welding. The tool comprises a liner and a base. The bottom of the liner is provided with a connecting seat, a plurality of mounting holes are formed in the connecting seat, and connecting columns are arranged in the mounting holes. Springs are arranged outside the connecting columns, a groove is formed in the surface of the liner, the section of the groove is in an arc shape, a cavity is formed in the liner, a water inlet is formed in one side of the cavity, and a water outlet is formed in the other side of the cavity. First pipe flanges are arranged on the water inlet and the water outlet, the water inlet is connected with a water inlet pipe, the water outlet is connected with a water outlet pipe, second pipe flanges are arranged between the water inlet pipe and the corresponding first pipe flange and between the water outlet pipe and the corresponding first pipe flange, and a circulating water pump is mounted between the water inlet pipe and the water outlet pipe. The tool is reasonable in structural design, a machined workpiece is convenient to cool, pipe mounting stability is improved, and the machining efficiency of submerged-arc welding and workpiece quality can be improved conveniently.
