During welding, the amount of heat present in weld

\r\nzones determines the quality of weldment produced. Thus, the heat

\r\ndistribution characteristics and its magnitude in weld zones with

\r\nrespect to process variables such as tool pin-shoulder rotational and

\r\ntraveling speed during welding is analyzed using thermal finite

\r\nelement analyses method. For this purpose, transient thermal finite

\r\nelement analyses are performed to model the temperatures

\r\ndistribution and its quantities in weld-zones with respect to process

\r\nvariables such as rotational speed and traveling speed during welding.

\r\nCommercially available software Altair HyperWork is used to model

\r\nthree-dimensional tool pin-shoulder vs. workpieces and to simulate

\r\nthe friction stir process. The results show that increasing tool

\r\nrotational speed, at a constant traveling speed, will increase the

\r\namount of heat generated in weld-zones. In contrary, increasing

\r\ntraveling speed, at constant tool pin-shoulder rotational speeds, will

\r\nreduce the amount of heat generated in weld zones.<\/p>\r\n","references":"[1] G. M. Xie, Z. Y. Ma and L.
