Abstract

Aluminum AA 1100 is an alloy of Al 99.05%, Si 0.24%, Fe 0.43%, Cu 0.17%, Zn 0.11%. The oxy-acetylene welding is a manual gluing without pressing where the surface to be joined is heated until it melts by the flame of acetylene gas with or without filler. The method used in this study is an experimental method with the process of joining specimens using oxy aceteline welding (C2H2 combustion with O2) and for the process of measuring the mechanical properties of the welding results using a bending test and tensile test. The measurement results on the oxy-acetylene welding process of AA 1100 aluminum plate using borax showed that the average tensile strength value was 74.43 MPa and the average bending strength of the specimen was 38.75 Kgf.
