In this study, Al 6061 T6 alloy was joined by friction stir welding method with the same parameters using with different profiled pins. As a result of the experiments carried out, the samples were subjected to metallographic examination, hardness measurements, tensile test and bending test. As a result of the examinations carried out, changes in we...

In this study, EN AW 6061-T6 Al alloy having a thickness of 6 mm was joined with a 5000 W fiber laser welding machine using different welding speeds (20, 25, and 35 mm/s) and shielding gas compositions (100% Ar, % 50 Ar + % 50 He, % 25 Ar + 75 He). In order to reduce the strength decrease in the weld zone, 5356 filler metal with a diameter of 1.2 m...

In this study, a 6 mm-thick 6061 T6 aluminum alloy was welded using fiber laser welding, and its mechanical and metallurgical properties were investigated. Full penetration autogenous welds were made at a constant laser power of 4.95 kW using a continuous-wave fiber laser and focal positions of −4 mm. In addition, the shielding gas content was chan...

In this study, it has been reported that Q345B steel combine with different steels using electric arc welding method and the mechanical properties were investigated. Produced by hot rolling processes, Q345B steel is a low-alloyed medium tensile strength and highly usable steel. The steel used contain less than 0.2% carbon and less than 0.55% silico...

In this study, 6 mm thick plates of Al 6061 T6 alloy are joined by laser welding at four welding speeds (40 mm × s ⁻¹ , 35 mm × s ⁻¹ , 25 mm × s ⁻¹ , and 20 mm × s ⁻¹ ). The welded joints are made using a 4000 W fiber laser welding machine. The effect of laser welding speed on the pores formed in the weld seam was investigated. In this manner, it w...

In this study, 6 mm thick plates of Al 6061 T6 alloy are joined by laser welding at four welding speeds (40 mm × s-1, 35 mm × s-1, 25 mm × s-1, and 20 mm × s-1). The welded joints are made using a 4000 W fiber laser welding machine. The effect of laser welding speed on the pores formed in the weld seam was investigated. In this manner, it was found...

Aluminum alloys (AA), which have been used a lot recently, provide better results in terms of mechanical properties. Since such materials are generally light and have good corrosion resistance, they are mostly used in aviation, defense, aerospace and automotive industries It can be seen that Al alloys are preferred in transportation sector especial...

I n the study, mechanical properties of martensitic steel X20CrMoV11-1 was investigated after being welded using Tungsten Inert Gas GTAW welding method at different weld positions PC and PJ-EN 6947 . The X20CrMoV11-1 steels have been widely used in thermal power plant applications in combustion chambers and other high-temperature parts. These mater...

TIG welding is a method often used for joining of light metals and high-alloy steels and it contains a number of risks as with other arc welding methods. If proper precautions are taken, safe working environment can be provided. Arc welding includes various hazards like dust, gas and smoke, compressed gas cylinders, harmful rays, high temperature a...

In this study, the fracture toughness of Fe2B boride layer on boronized AISI 304 stainless steel was investigated. Samples were boronized in an indirect heated fluidized bed furnace with Ekabor 1 (TM) boronizing agent at 1123 K, 1223 K, and 1323 K for 1 h, 2 h, and 4 h, respectively. The boride phases were investigated by X-ray diffraction (XRD) an...

In this study, kinetic examinations on boronized X45NiCrMo4 (DIN 1.2767) and 90MnCrV8 (DIN 1.2842) steel samples are described. Samples were boronized in indirect heated fluidized bed furnace at 1123 K, 1223 K, and 1323 K for 1 h, 2 h, and 4 h. Morphologically and typically examinations of borides formed on the surface of the steel samples were stu...
