Transient processes in welding inverters and their influence on the stability of welding current
Russian Electrical Engineering, 2017Inverter converters used for dc-arc electric welding have been manufactured by many foreign and domestic companies and showed good results for decades. Until recently, ac welding was carried out only at an industrial frequency of 50 Hz. Earlier, we suggested carrying out arc welding at an increased frequency within the range of 25–75 kHz, proving it to

Current Research Into Laser Welding Aluminium Alloys
SPIE Proceedings, 1989ABSTRACT Although welding experiments on light alloys (aluminium or titanium based) have been performed since the beginning of the 1980's, the relative techniques have rarely been applied to production. The major difficulties in laser welding these alloys is only partially due to the differing thermal properties of the materials: another feature of ...

Toughness and Internal Friction of Weld Metal Welded by High-Current MAG Welding
Advanced Materials Research, 2011Low-temperature impact test on four different kinds of weld metal welded by different technologies of high-current MAG welding was carried out in this paper. The results show that different materials and different welding parameters have different effect on impact energy.

The influence of a welding current modulation on weld seam formation
2016The influence of a welding current on formation of weld is considered in the article. The advantages of welding by the modulated current are found out in comparison with welding by a direct current. It is determined that the high-frequency pulses of a current increase pressure of an arch, its stability and penetration.

THE WELDING CURRENT MAGNETIC FIELD
2019Застосування одностороннього високошвидкісного зварювання обмежено зниженням стабільності процесу, якості і ударної в'язкості зварних з'єднань. Стабільність процесу визначає формування зварних швів, якість і ударну в'язкість зварних з'єднань. Тому підвищення стабільності процесу, якості і ударної в'язкості зварних з'єднань є важливою науково-технічною ...
