Abstract

This study aims to analyzed the effect of male-female chamfer configuration in a rotary friction welding of alumunium 6061. The male-female chamfer configuration tend to make an inner chamfer and outer chamfer shape between two connected materials. The chamfer angle analyzed varies in 300, 450, and 600 where the friction time also varies in 1 and 2 minute. The results shows that the tensile strength increased along with smaller chamfer angle and longer friction time. The largest tensile strength of 33.92 kgf / mm2 was obtained in the variation B30. The smallest tensile strength of 12.20 kgf/mm2 gained in specimen A60. Smaller chamfer angle leads to a larger friction areas which caused the welding contact areas also wider. The male-female chamfer method slopely increase the contact area by 78%, 33% and 12% than normal circle profile.

Abstract

The hard facing process is the welding process of SMAW by using a hard facing DIN 888 electrode as a hard facing to replace conventional cutting tool material. The purpose of this analysis is to determine the effect of preheating temperature on the welding of hard coatings on AISI A35 low carbon steel. The results of this study are expected to obtain optimum hardness on coated steel, from variations in the temperature of the preheating. there will be a change in the hardness of the welding deposit, the deposit will be used as cutting tools. The results of this study can be used as guidelines for making cutting tools.
