Abstract

This study analyzed the treatment results of low carbon steel plate splicing with Alumuium 6061. The material in the form of a dial plate, plate thickness of each plate 1 mm to 2 mm for steel and aluminum plate. Grafting using point welding (spot welding). Filler using steel alloy-All 10 mm diameter with a thickness variation of each filler - 1mm and 2 mm respectively. Grafting with the welding point, specimen 1 using 2.67 V output voltage and welding time of 2.5 seconds, while the second specimen using the output voltage of 2.67 V and the welding time of 5 seconds. Welding results indicate that the specimen 1 can be continued, while the second specimen failed. Then do a test specimen 1 in the shear load and testing of Metallography. From the test slide in prices get broken sliding 1.56 KN. Metallographic testing is at the weld (weld metal), and HAZ regions. From the results of metallographic testing in getting the metal filler can not be binding (no ties) with the parent metal of steel, while the filler metal can bind to (happen bond) with the parent metal allumunium. different melting points far adrift between two base metals are in connection thus causing the quality of the connection did not work properly.
