Geometry of Pulse Current GMA Weld
2017Variation in geometry of P-GMA weld as a function of pulse parameters has been discussed in order to understand the control of welding process to produce desired weld geometry of required chemistry for an acceptable weld quality. The mechanism of the control of weld geometry governed by its basic aspects as penetration, width, reinforcement, form ...

ENERGY CHARACTERISTICS IN WELDING CURRENT REGULATORS
2020Заваръчните регулатори на ток се прилагат при многопостови заваръчни агрегати, които се използват в роботизирани комплекси за заваряване, например при заваряване на статорни пакети на ел. двигатели, или големи газопроводни тръби, при които едновременно се заварява с 2-4 горелки.
