Welding engineering self generating electric welder without power supply 250A
now hope that the technology for pipeline welding, in cooperation with enterprises, the development of a pipeline all position ultra narrow gap welding. Focus on the development of arc welding generator and welding control system. The DC arc welding generator driven by gasoline engine is developed in view of the requirement of field pipeline welding. The instantaneous waveform sampling welding current and welding voltage, direct control of IGBT pulse signal conduction through operation circuit for adjusting excitation current of synchronous generator, the external characteristics of the arc welding generator to control rapid response. By changing the depth of the welding voltage feedback and the welding current feedback, the two output of the arc welding generator is obtained. Welding in the field of large diameter pipeline, decline in output characteristics for cellulosic SMAW root welding; constant voltage output for ultra narrow gap welding fill and cap.
online brand name: Ito self generating electric welder experimental results show that the characteristics of the arc welding generator with fast response speed, welding parameter Number can be adjusted continuously, adjusting range can meet the actual demand. According to the requirement of the control system for the welding of ultra narrow gap in the whole position of pipeline, the control system of ultra narrow gap welding is developed. The control system adopts SOC single chip microcomputer as the control core, and adopts the subsection control method to divide the pipeline into 24 sections. By the control system, the automatic adjustment of welding parameters in different welding positions is realized. In addition, the control system also realizes the control of each function key and display system of the ultra narrow gap welding machine. The control panel is simple, practical, functional and visual. The control system has high stability and fast response.
