Short Circuit MAG/MIG Welding and Fast ROOT Modified Short arc Welding Process for Sheet Metals Welding with Diverse Air Gap

Abstract

The outcome of an analysis allocating with welding of sheet metals with diverse air gap using short circuit MAG welding process and Fast ROOT custom-made short arc welding methods have been presented. Welding turns were made below different conditions and through each run; the diverse process parameters were incessantly observed. It was found that fewer HAZ and maximum welding speed are reached under an exact welding condition with quick ROOT method with the emphasis on arc constancy. Welding result explains that the customized short arc exhibits a higher electrode melting coefficient with almost spatter-free droplet alteration. In adjusting the short circuit time, the infiltration can be prohibited with only a small change in electrode deposition. In the mixing modified arc welding with pulsed MIG welding the working envelope of the process is deeply extended allowing thicker material sections to be welded with enhanced weld bead aesthetics. Fast ROOT is a customized short arc welding process using automatic or mechanized welding method based on the dip transfer welding, characterized by controlled substance deposition during the short circuit of the wire electrode to the work piece.
