Gmaw Welding

This paper proposes the development of the methodology to be carried out for the metal joining process through the GMAW welding process in the Fanuc LR Mate 200iD industrial robot. The parameters or properties were considered for the application to be as efficient as possible, such parameters as speed of application, characteristics of the filler material, gas to be used as welding protection. The GMAW welding process can be applied semiautomatically using a hand gun, in which the electrode is fed by a coil, or an automatic form that includes automated equipment or robots. The advantages and disadvantages of the GMAW welding process applied in a manual and automated way were commented. The mechanical properties of the materials to which said welding can be applied were investigated; The materials with which this type of welding can be worked are the high strength materials, which are used in the automotive industry, for the forming of sheet metal. To know the properties of the material, destructive tests were carried out on the test material to be used, as well as the mechanical properties of the welding.

Abstract The aim of this work is to carry out the design of experiments that determine the influence of the welding parameters using Taguchi’s method on the grain size, HAZ, and the degree of dilution in 6063-T5 alloy. The welding process used is GMAW and the welding parameters are power, welding speed and bevel spacing. The study of the influence of the welding parameters on the measurements made in the welding (which are the size of heat affected zone, the degree of dilution, and the grain size) allows one to determine the quality of the joint . In addition, the welding parameter most influential in minimising the three measurements will be determined.

This paper presented the effect of DE-GMAW (Double electrode gas metal arc welding)resistance on mechanical and physical properties of aluminium alloywelded. DE-GMAWis amethodof welding process that use two electrode. A non consumable torch is added to bypass the current inorder to reduce the heat input. The variation resistance used were 15Ω, 30Ω and 45Ω. Universaltesting machine and Vickers microhardness were used to measured mechanical properties of weldmetals with respect to strength and hardness. The microstructure was investigated by microscopeoptic with 100 x magnification. The grain size of weld metals with resistance value 30Ω is finer than15Ω and 45Ω. Dye penetrant test shows DE-GMAW welding machine that made have goodperformance because it can produce welding joint without surface crack. The results show thatresistance values optimum to DE-GMAW welding on aluminium alloy 5051 with 4 mm thickness is30Ω. It can be seen from the tensile test that shows the highest tensile strength is found in the DEGMAWwelding with resistance values 30Ω.

This paper presents current technologies used for pipe welding. Welding processes such as Tandem and Hybrid (Laser-GMAW) welding are compared to regular 1-wire GMAW. The device used for positioning the welding head is an anthropomorphic robot, as this type of robot provides everything needed for the application: low cost, flexibility, sufficient payload and precision.

Gmaw Welding

The technology of the manufacturing industry is developing rapidly, where the rapid development of this technology cannot be separated from the welding field. In the welding process, thermal heat is used until the material melts, the heat change will also cause changes in the structure, stress and also deformation of the material. This is because the more carbon elements are captured, the more martyred structures are formed. This causes an increase in the value of hardness and tensile strength values in the material. The purpose of this study was to determine the effect of the temperature of the cooling medium oil, salt water, water. dromus, and free air in GMAW welding on the tensile test of ST 60 steel. To determine the effect of cooling temperature medium of Oil, Salt Water, Dromus Water, and Free Air on GMAW welding toward the tensile test and hardness test of ST 60 steel. Several means used for testing are calculating the tensile stress Mpa and HVN hardness. This research method used the experimental method. The GMAW welding process variations of coolant were used, such as oil, salt water, dromus water, and free air with a time of 25 minutes and electic current of 100 A. The type of seam used was a V type with angle of 30o. The tests carried out were tensile and hardness test. The highest average value of the tensile stress from the the salt water coolant specimen was 490.23 Mpa. The highest average value of the tensile strain from free air specimens was 35.45 Mpa. The average value of HVN hardness from Oil specimens was 208.3 HVN, salt water was 231.0 HVN, Dromus water was 215.5 HVN, and free air was 228.0 HVN. From the average value of HVN hardness, the highest value observed was the salt water specimen with 231.0 HVN.
