Problems solved by technology

Its disadvantages are: the equipment is relatively complicated and expensive, and the JH-150 precision automatic welding machine used in it has a large investment and unit cost. Secondly, it has high technical requirements and needs to be automatically controlled by programming, which is not flexible enough.

Embodiment 1

[0021] Such as figure 1 As shown, the whole welding system can roughly be regarded as composed of two parts according to the function: (1) the power supply system including power supply, transformer, electric meter, etc., which is the part that provides energy for hydroelectric welding, and is also the part for understanding welding process parameters According to the test, the required voltage for welding can be welded from 0V to 380V; (2) the welding zone consisting of the workpiece to be welded and the electrolyte can be welded by using a water-soluble salt solution. Including water-soluble nitrates, nitrites, oxalates, carbonates, bicarbonates, phosphates, sulfates, sulfites and acetates, one or more compound solutions of the above. If the content of each component is a single type of salt solution, the highest is the saturated solubility of the salt. For example, in a NaCl solution at 20°C, a maximum of 36 grams of NaCl can be dissolved in 100 grams of water; The percent...

Abstract

The invention is a hydro-electric welding method, belonging to material coupling technique field. The invention specific method are as follows: welding circuit design of arc formed by electrolyte; using commercial AC power supply to connect positive electrode of power supply to the electrolyte, and connecting negative electrode to metal to be welded, contacting the metal to be welded with the electrolyte surface, producing arc for an instant of contacting, here partly metal melting; controlling two parts of metals to be welded to contact with each other during producing arc, until cooling to two parts of metals welding together. The invention with simple device, easily controllable welding process, can not only weld the same kind of metal, but also can weld different kinds of metal, with more simple and convenient use characteristics and applicability than present majority of welding method. The arc designed and produced by the invention can weld familiar metal wire and metal sheet.

Description

technical field [0001] The invention relates to a method in the field of welding technology, in particular to a hydroelectric welding method. Background technique [0002] Welding and connection is one of the key technologies in the development of modern industrial production and science and technology. In the process of scientific research and production practice, almost all the fields involving the development, selection and use of materials have welding problems of metal materials. For the connection of metal wires and metal sheets that are often encountered in production practice, commonly used methods include manual arc welding, brazing, resistance welding and explosive welding. [0003] The traditional metal welding technology can be divided into the following three categories according to its principles: (1) fusion welding, using an external heat source to locally melt the area near the interface of the connected components into a liquid, and then cooling and crystal...
