ABSTRACT

This chapter introduces the basics of the technique, and provides a summary of the application of Regulated metal deposition (RMD) technique on different steels and its beneficial outcomes. The developments of new arc welding processes were aimed to overcome the restrictions of traditional short arc waveform by enabling new shapes of the arc curve. In the RMD process, through the opening phase of the metal-transfer cycle, the droplet is formed initially on the melting tip of the electrode wire. RMD technique was experimented instead of conventional short arc gas metal arc welding process and it was observed that the root joints showed better soundness and integrity to even pass the X-ray test reducing the rework, hence increasing the productivity. RMD technique was reported to be used on SS 316L tubes with a diameter of 0.5–34in. in the root pass primarily.
