Abstract :
Wire and Arc based Additive Manufacturing,
shortly known as WAAM, is one of the most prominent
tech- nologies, under Additive Manufacturing, used for
extensive production of complex and intricate shapes. This
layer by layer deposition method avails arc welding
technology; Gas Metal Arc Welding (GMAW), a
competitive method in WAAM, is the conducted
manufacturing process.
It is a sum of heat source, originated from the electric
arc, and metal wire as feedstock. The metal wire from the
feedstock, melted by arc discharge, is deposited layer by
layer. Another material can be added on to the top of
deposited layer by replacing the feed wire from the stock, to
fabricate a bimetallic structure. The purpose of this study is
to collect the salient datum from the joining of two
dissimilar metals. A combination of stainless steel and mild
steel are considered. Proper deposition parameters, welding
current along with voltage, bead width efficiency for both
the metals were acquired. As a result, the physical
properties of the dissimilar joint were approximate to the
bulk material.
