Modular electromagnetic pulse welding platform

Abstract

The invention provides a modular electromagnetic pulse welding platform which is characterized by comprising a coil as well as a base I and a base II which are fixedly arranged on the upper surface of a workbench. The coil is of an inverted U-shaped structure, one end of the coil is connected with the upper surface of the base I through a connecting plate I, and the other end of the coil is connected with the upper surface of the base II through a connecting plate II. The lower surface of the base I is fixedly provided with a wiring terminal I, and the lower surface of the base II is fixedly provided with a wiring terminal II. During welding work, the pulse current flows from a pulse generator, sequentially flows through the wiring terminal I, the coil and the wiring terminal II through a lead and finally returns to the pulse generator to form a closed loop. The beneficial effects of the modular electromagnetic pulse welding platform are undoubted; due to a modular design, the coil can be rapidly replaced to adapt to different welding conditions; and the modular electromagnetic pulse welding platform is simple in structure, relatively low in cost, suitable for welding small materials and more safe in the operating process due to the additional arrangement of a protective cover.

Problems solved by technology

[0003] Traditional welding methods include submerged arc welding, resistance welding, manual electrode arc welding, argon tungsten arc welding and carbon dioxide welding. Among them, submerged arc welding is difficult to weld in space, and has high requirements on the quality of weldment assembly and is not suitable for welding thin plates. and short welds

Resistance welding equipment has high power, large equipment investment and difficult maintenance

It is difficult for a high-power welding machine to feed the load of the grid. If it is a single-phase AC welding machine, it will have an adverse effect on the normal operation of the grid.

Manual electrode arc welding has high requirements on welder operation technology and high welder training costs; poor working conditions, electrode arc welding mainly depends on the manual operation and eye observation of the welder to complete the whole process, the welder's labor intensity is high, and he is always exposed to high temperature baking and toxic In the smoke and dust environment, the working conditions are relatively poor, so labor protection must be strengthened; production efficiency is low, electrode arc welding mainly relies on manual operation, welding electrodes must be replaced frequently during welding, and weld slag must be cleaned frequently, which is comparable to automatic welding ratio, welding productivity is low

For carbon dioxide welding, there are more metal spatters during the welding process, and the arc atmosphere has strong oxidative properties, so it is not possible to weld easily oxidized metal materials

However, the electromagnetic pulse welding used in industrial production is expensive and has a complicated structure, so it is not suitable for welding small parts.
