Parameters

Automatic numerical control gas electric vertical welding machine is an automatic welding equipment independently developed and produced by Nanjing NAEC Electric Co., Ltd. according to the characteristics of forward / backward construction of storage tank, combined with the technology of self protective vertical welding equipment in the United States and trolley type gas electric vertical welding equipment in Japan. It can be used in both forward and backward construction. In the process of automatic welding, the servo system and closed-loop control welding car are used to control the upward lifting speed, so as to achieve the effect of stable welding pool and complete the automatic welding project of longitudinal weld of large storage tank, blast furnace and tower. Its main feature is that the water-cooled copper slider forces the single pass welding longitudinal seam to form at one time, which greatly improves the welding quality and efficiency, and reduces the labor intensity of the welder.

The whole set of equipment is composed of welding system and bench, welding windproof frame (with transverse travel control system), welding lifting operation platform trolley, welding automatic control system, swing control system, cooling water circulation system, etc. The walking device adopts modular design. By adjusting its installation position, it is convenient to realize the forward and backward dual-purpose function. The configuration of welding swing control system is linear swing device.

Adopting the patented "numerical control adaptive gas electric vertical welding car technology (patent number: zl200920231033.1)" PLC full closed-loop program control technology, it overcomes the problems of low reliability and easy damage of analog circuit under the traditional analog circuit control mode, and ensures that the equipment can work continuously and stably under the complex and harsh construction environment. The welding effect of vertical seam can also avoid the repair process of arc starting section, which is similar to that of tank loading construction, and further improve the automation degree of welding. Equipped with large capacity cooling water tank, can ensure the needs of continuous construction in high temperature environment.
