Abstract

Friction Stir Welding (FSW) is a welding process that is promoted with little cost and good connection quality. That is because it does not need filler metal and can eliminate or minimize the number of cracks and porosity defects. The FSW principle uses tools that rotate and move across so that the material occurs forging at the center of the weld and finally melts. The FSW welding process variables are tool parameters and welding parameters. Welding parameters include rotational speed, tool slope, travel speed, shoulder penetration, probe penetration, probe shape and dimensions, shoulder shape and dimensions, material tools, and others. In this study, the effect of temperature variation of heating elements used in welding polyethylene (PE) material on tensile strength by tensile test is examined. From the tensile test data, it is found that the higher the temperature of the heating element during the FSW process, the feeding translation tool will increase and the tensile strength of the FSW joint results will also increase and vice versa. The lowest tensile strength occurs at temperatures of 0 ° C (without preheating) and 100 ° C (using preheating), namely 4.465 MPa and 14.25 MPa. The highest tensile strength occurs at heating element temperature of 140 ° C which is 24.71 MPa while the tensile strength of polyethlyene material without FSW connection is 29 MPa.Keyword : friction stir welding, feed rate, polyethylene, the tensile strength of welded joints.

Abstract

Friction Stir Welding (FSW) or often called friction welding is one of the mechanical welding methods using friction between the surface of the tool and the surface of the material so that friction occurs and causes heat on the surface of the material for the welding connection process. The friction surface impacts translational motion caused by the rotational pressure of the tool and axial force (forging) to push the friction surface. Retrieval data that will be varied on translational motion speed starting from 12.5 mm / minute, 20 mm / minute and 25 mm / minute. In this study the shape and dimensions of the material used were 100 mm long, 50 mm wide with a thickness of 5 mm while the types of tools used in this study used a type of cylinder with dimensions of 6 mm pin, 25 mm shoulder and 50 mm tool length. In this study the data collection process uses thermal devices and jigs. Where the function of this thermal heater is to lift the temperature of the material that is in accordance with what is needed (melting point). And the function of this jig is to grip or clamp the material on the position of the horizontal milling machine. The purpose of this study was to study the method of pulling welding friction using the Friction Stir Welding (FSW) method on nylon 6 material using the ASTMD-638-IV standard.Keywords : Stir friction welding, weld surface, friction weld, polyamide polymer.

Abstract

Welding according to DIN (Deutsche Industrie Norman) is a metallurgical bonding on the connection is done in the melting or liquid state. In other words, the welding is the joining of two pieces of metal into one doneby way of heating or melting, where both ends of the object that will be spliced with eyes melt made the pin on the tool or the heat gained from the pins on the rounds a specified rpm. each specimen, material AISI 4140 steel is used with a diameter of 6 mm pin welding position horizontally (flat), the used temperature 70 ° c, 75 ° c, 80 °c, and a round of rpm used 400 rpm, 500 rpm, 700 rpm, in the execution of welding the welding method using FSW (Friction Stir Welding). Then pull the values taken on the area of welding. From the results of the research of pull, the value of the temperature of 75 ° c with round 700 rpm higher tensile strength of temperature of 70 ° cand 80 ° c.Keyword : Temperature, Rpm Spin, Friction Stir Welding, Welding, Surface Polypropilene.
