Recent Advances in Inverter Controlled, Gas Shielded Arc Welding Power Sources and Other Applications

This report summarizes trends of arc welding processes and power sources, especially, recent advances of inverter controlled power sources with various kinds of new current wave control method for gas shielded metal arc welding process.

The features of inverter controlled machine are not only compact and lightweight design but also various improvement of weldability and control of arc welding phenomena such as metal transfer arc plasma characteristics, bead formations etc and features will contribute to much more automization of arc welding.
