Recently, amorphous alloys have attracted many researchers' attention for amorphous structures and excellent properties. However, the welding of amorphous alloys to traditional metals in the microscale is not easy to realize in the process with amorphous structures unchanged, which restrains the application in industry. In this paper, a new method of welding Fe-based amorphous alloys (GB1K101) ...

This study aims to determine the effect of protective gas flow rate on tensile and shock strength welded joints dissimilar metals, namely aluminum 5052 – galvanized steel with Al-Si 4043 filler using argon as a shielding gas. The parameters used in this were 14, 17, 20 liters/minute current 80 A. results showed that higher gas, lower porosity defects occurred welding results, resulting values. ...

Friction stir welding (FSW) is a solid-state process capable of joining wide range light metals. However, liquation and solidification may occur during dissimilar metals which leads to eutectic formation. This article aims discover the influence tool rotation speed on formation structure friction aluminum magnesium. To do so, was performed at 600 950 rpm join pure ECO-AZ91 magnesium alloy in la...

Dissimilar Welding of Austenitic and Martensitic Stainless Steel Joints are commonly preferred in Nuclear Reactors where high temperature applications needed. There has been a huge demand for materials which sustain corrosive environment with rupture strength along pressure. These can be directly replaced the traditional nickel based alloys to compensate cost cutting satisfy requirements. weldi...

Welding processes that generate fumes containing toxic metals, such as hexavalent chromium (Cr(VI)), manganese (Mn), and nickel (Ni), have been implicated in lung injury, inflammation, and lung tumor promotion in animal models. While federal regulations have reduced permissible worker exposure limits to Cr(VI), this is not always practical considering that welders may work in confined spaces an...

Vaporizing foil actuator welding (VFAW), an impact method, was used for the first time to produce high strength welds between SiC-reinforced 8009 aluminum metal matrix composite (MMC) (8009/SiC/11p) and 7075 alloy (AA7075). Microscopic characterization of dissimilar weld revealed multiple heterogenous microstructural zones including unbonded zone at center, a flat interface, wavy trapped jet co...

Laser welding-brazing was used to join cemented carbide WC-Co and steel dissimilar materials. In this study, high-speed welding adopted. The effect of parameters brazing filler metals on the macrostructure, elemental diffusion, micro hardness thermomechanical behavior analyzed using optical metallography, scanning electron microscopy, probe micro-analysis, test, finite element method (FEM) base...

The discovery of new metal alloys and the technological advancement in welding processes are key resources for aerospace industry to obtain cost reduction better reliability. Thus, welded joints dissimilar materials such as aluminum titanium have been explored due their combined low density high mechanical performance. Otherwise, metals may present deleterious factors joint formation intermetal...
