Abstract

As an arc voltage decreases, an arc length shortens and a surface of molten pool right under the arc becomes dented at a high current range in gas metal arc welding (GMAW) using 100% CO2 as a shielding gas and a carbon steel solid wire. And the arc is finally generated at a lower position under the surface of the molten pool and in a space formed by a wall of molten pool. A spatter generation level is extremely low even at a high current range in this metal transfer mode. This arc phenomenon is referred to as “buried arc,” and the arc stabilization technique at the high current buried arc more than 450A is described in this report.

The arc phenomenon taken by an X-ray observation system and a high-speed video camera were observed using a low-carbon steel as a base metal, a carbon steel solid wire of 1.2 mm, 100% CO2 as the shielding gas, and travel speed of 30 cm/min. The high current buried arc stabilized by an external characteristic control of welding power source (maximum current 1000 A, maximum wire feed rate 100 m/min) showed three kinds of metal transfer mode including rotating transfer mode at the current range more than 450 A. Consequently, a new current waveform control combined an adequate gradient of the external characteristic and a low-frequency voltage oscillation, which realizes more stable high current buried arc, has been developed in order to improve a weld bead formation using these particular metal transfer modes.
