Abstract

The welding process has been essential to increasing productivity in numerous industries across Thailand. There are several welding processes to choose from, and the welding process to use will be determined by the suitability of the production in that industry. Another important consideration in welding is to keep the mechanical properties of the joint area as close to the parent material workpiece as possible. This research aims to select the optimum parameter for rotary friction welding aluminum round bar AA6063-T5. That is according to the DIN 50125 type B standard test. The optimal condition consists of welding rotational speed, welding time, and welding pressure rated. The experiment used a three-level factorial design (3k). By a 95% confidence, all of the factors studied had a significant impact on rotary friction welding. A rotational speed of 2,000 rpm, a welding time of 26.97 sec and a pressure of 30 bar resulted in a maximum weld strength of 179.148 MPa.
