This study aims to determine the effect of variations in welding current and distance on the strength of the weld on 316L stainless steel material through a tensile test. The type of research method and data collection will begin through the welding process of eighteen pairs of stainless steel plates using spot welding. Welding will be carried out with variations in the current and distance of the welding points. After carrying out the stainless steel welding process, a tensile test will then be carried out to determine the effect of current variations and the distance of the welding points on the strength of the welded joints in stainless steel. Based on the results of the test data obtained, it shows that a voltage of 1.75 V produces an electric power of 6317.88 Watts and a voltage of 2.20 V produces an electric power of 9249.93 Watts with a constant welding time of 2 seconds. The highest tensile strength is specimen D with a spacing of 10 mm and a voltage of 2.20 V, which is 14,765 N, while the lowest tensile strength is specimen C with a spacing of 30 mm and a voltage of 1.75 V, which is 10,224 N. At a current voltage of 1.75 Volts, the welding distance is 20 mm produced is 3490.17 Mpa and a current voltage of 2.20 Volts 20 mm welding distance produced is 3682.33 Mpa the results obtained the greater the current used, the greater the resulting tensile strength. The value of the elastic modulus is inversely proportional to the current strength and welding distance. This can be shown in the results of the tensile strength test data obtained, namely specimens with a current of 1.75 volts with a welding distance of 10 mm have a greater modulus value than specimens with a current of 2.20 volts with a welding distance of 10 mm.

The manufacturing process in the automotive industry is in dire need of resistance spot welding machines. Because it was easier to use, highly effective, and effective in functioning. However, there were sometimes still connection problems that were still of poor quality, both nuggets and areas that are subject to electrode pressure. To get a quality welding connection, a machine was needed that was able to carry out good material preparation in the form of sanding, able to set the welding current analogously, able to set the time with an automatic timer, able to apply pressure on the electrode measurably during the welding process. The research aimed to design a prototype of resistance spot welding material preparation that could adequately carry out material preparation and welding using a Bluetooth system connected to a mobile phone. The research methods carried out were as follows: first, designing the machine using Autodesk Inventor software, then the device was made with a focus on material preparation prototypes, then the machine elements were made for the material clamping rail, then the machine elements in the control section using Bluetooth connected to the mobile phone, the machine was tested, then the connection quality testing process was carried out on the tensile testing machine. The results showed that the design results had been made using elbows and iron plates with threaded rails with a length of 650 mm, which became material clamping rail grooves with a drive using window motors controlled by Bluetooth on the Arduino circuit. The test results of welded joints show that the roughness is 0.20 μm which has the highest tensile strength.

Dissimilar metals have found wide use in electric power generation, electronics, reactors, nuclear, petrochemical, chemical industries, civil construction, vessels, and heat exchange as well as several other industries. TIG welding (Tungsten Inert Gas Welding) is a type of electric welding that uses tungsten as the electrode material that is not consumed. Brazing is a way of joining metal materials through a heating process with an adhesive or filler material that has a melting point below the material to be combined or connected. The main objective of this study was to determine the shear strength and microstructure of the weld area that was joined by the brazing method. From the results of the shear strength test, there is a comparison of the difference in the shear stress strength. The results obtained indicate that where the shear stress test at a flow rate of 5 liters/minute of protective gas gets the highest shear stress value of 108 N/mm2, compared to the shear stress test with a gas flow rate of 10 liters/minute, the shear stress value is equal to 97 N/mm2, but at the protective gas flow rate of 15 liters/minute the lowest shear stress value was 76 N/mm2. The results of the microstructure obtained the result that the protective gas flow rate of 15 liters/minute got the lowest value due to a decrease in the amount of Si elements, resulting in the lowest shear stress value.
