Pipes of small diameters of up to 100 mm are used at various industrial and agricultural facilities. The methods of manual arc welding or automatic welding are traditionally used for welding the pipes. The issue of using supercapacitors in equipment for magnetically impelled arc butt welding (MIAB) process, in order to reduce peak loads on the electrical network is considered. The need for such equipment is primarily determined by the tasks of «green» technologies. Application of supercapacitors in power sources allows ensuring further on the optimal parameters of pulse welding processes, in order to improve their quality and work productivity. A prototype of a new generation of power source for MIAB welding of pipes of a small diameter in the field and stationary conditions using an autonomous power supply source has been developed and manufactured. 15 Ref., 2 Tabl., 11 Fig.
Keywords: generators of welding current, magnetically impelled arc butt welding, autonomous sources of powerful current pulses and power supply, supercapacitors.
