Abstract
In this study, an experimental method for the selection of optimal welding for joining metals there are several methods which they are used for joining metals, that it includes using welding brazing, Metal Inert Gas (MIG) Welding and Gas Metal Arc Welding is an arc welding process, in which the weld is shielded by an external gas (Argon, helium, CO2, argon + Oxygen) or other gas mixtures is one of the widely used techniques for joining ferrous metal. (MIG) welding process offers several advantages like joining of unlike metals, low heat effected zone, absence of slag etc, Thus the welding condition has to be selected carefully. By studies, the quality of welded joints depend upon three important factors are: type of power supply (DCSP, DCRP or ACHF), type of inert gas used for shielding and type of material the welded joint. In this paper deals with the investigation of Tensile strength of welded buttly joints, by three types of welding (Brazing welding), (MIG welding) and (Steel rod welding). Where it was selected the steel for preparing the specimens and it was tested the tensile strength of the welded joints where tested by a universal tensile testing machine in laboratory and the results were evaluated, which it confirmed importance of tensile testing that have to determine whether butt welded joints fulfill all of the required standards before use and also it should be select the type of weld the suitable of the type of metal.
Keywords: Welding, Tensile strength, Buttly joints, Machine, Samples, Steel.
