Effect of main arc voltage on arc behavior and droplet transfer in tri-arc twin wire welding
Journal of Materials Research and Technology, 2020 Increasing the weld deposition rate invariably increases the welding heat input in monofilament arc welding or high efficiency twin wire arc welding and hence cannot be easily optimized to satisfy the needs of special applications requiring high weld ...

Thermal and structural modelling of arc welding processes: A literature review
Measurement and control (London. 1968), 2019 This paper presents a state-of-the-art critical review of the thermal and structural modelling of the arc welding process. During the welding process, high temperature in the welding zone leads to generation of unwanted residual stresses and results in ...
