Abstract Submerged arc welding (SAW) has been performed using slag-fresh flux mixture on duplex stainless steel plates. Experiments were performed by recycled slag-fresh flux mixtures with iron powder; iron powder is mixed to maintain and enhance the weld strength. The effect of composition variation of slag-fresh flux mixture on weld bead geometry parameters have been investigated quantitatively. Weld bead characteristics viz. bead width; bead height; penetration area; reinforcement area, form factor and dilution were observed by metallography operations for each experiment. For varying the composition of slag-fresh flux mixture, mixture design technique; Scheffe Quadratic Model (SQM) was used. Empirical relations were developed for weld bead characteristics in terms of fresh flux, slag and iron powder and statistically checked for significance. Finally, recycled slag-fresh flux composition was optimized using desirability approach.

Submerged Arc

In submerged arc welding (SAW), weld quality is greatly affected by the weld parameters such as welding current, traverse speed, arc voltage and stickout since they are closely related to weld joint. The joint quality can be defined in terms of properties such as weld bead geometry and mechanical properties. There are several control parameters which directly or indirectly affect the response parameters. In the present study, an attempt has been made to search an optimal parametric combination, capable of producing desired high quality joint in submerged arc weldment by Taguchi method coupled with weighted principal component analysis. In the present investigation three process variables viz. Wire feed rate (Wf), stick out (So) and traverse speed (Tr) have been considered and the response parameters are hardness, tensile strength (Ts), toughness (IS).
