Abstract
Energy storage device is a very critical electrical component used at converter of the many locomotives. The energy storage devices are made up of AISI 1040 steel cases or boxes. Bulging effects in these boxes exerts tensile load on welded joint and breaks them. AISI 1040 is having good weld ability. The boxes of these materials are joined with MIG welding with the filler metal of ER 70S-6. In order to improve its properties the effects of various parameters such as weld current, arc voltage, and electrode feed rate, torch travel speed, torch to work piece distance is need to be studied. In this paper the effects of all above parameters on two main parameters VIZ tensile strength and throat thickness are discussed. As throat thickness increases, tensile strength will also increase. Increase in voltage and current decreases strength initially but increases after some value. Electrode feed rate is varying with current. Torch to work piece distance varies with the arc voltage. Throat thickness increases with decrease in torch travel speed. In all the reviews optimization of the parameters are done and validation of the same is carried out.
