Welding System

Purpose: Welding is one of the important processes for the manufacture of a wide varietyof products. Most of the manufactured products have to be produced by welding due to itsgreater productivity and economical viability. Still quality has to be enhanced in the products.To attain the perfect quality in weld a new attempt has been tried out while existing processare being optimized. In this direction, the conventional Gas Metal Arc Welding (GMAW) hasbeen developed to encourage high welding performance variant. Influence of changingfiller metal geometry is one of the ways to improve the capability of giving high depositionrate and penetration. Accordingly, a flat wire arc welding system has been developed andweld bead characteristic has been investigated. The overall results show that, the proposedtechnique of changing wire electrode geometry can be used effectively to improve the weldbead characteristics. In this article, how does a change in electrode geometry contribute tothe weld quality in manufacturing industries, is well- verified by experimental results, whichare also explored here.

Welding System

This paper designed a double-electrode GMAW(gas metal arc welding) system. This system includes main arc and bypass arc. Main arc (Base metal current: Ibm) is supplied with Constant Current power (CC mode) and bypass arc (bypass current: Ibp) is Constant Voltage power (CV mode). Main arc electrode used common carbon wire, bypass arc electrode used water cool copper. Welding experiment shows this DE-GMAW can change common metal transfer into spray transfer with lowest critical total current (Itotal) 200 amps. When Ibm decreases and bypass voltage increases, this critical current will increase and it is less than 230 amps when keeping spray transfer. High speed video proved that metal transfer is changed from spray transfer to globular transfer.
