Temperature profile and history can be used to characterize a welding process. This paper applied Rosenthal's thermal solution of a moving heat source over infinite solid to grab ideas how parameters involved in the welding process affect temperature profile and temperature history of selected nodes. Based on parametric study, it can be concluded that higher thermal conductivity caused shallow penetration since the embedded heat tend to spread out to the cooler region. To obtain equal penetration the power should be increased, but this caused the faster cooling rate. Increasing the welding speed has equal influence with elevating the specific heat that causes narrower isothermal lines although their length insignificantly altered. © 2006-2016 Asian Research Publishing Network (ARPN).
