Friction stir welding super duplex stainless steels UNS S32750 and evaluation of microstructure, mechanical and corrosion properties

Friction stir welding (FSW) is considered to be the most significant development in solid state metal joining processes. This joining technique is energy efficient, environmentally friendly, and versatile. In particular, it can be used to join high-strength aerospace aluminum alloys and other metallic alloys that are hard to weld by conventional fusion welding. The project aims to join Aluminum 6063 alloy plates by FSW and emphasize the (1) mechanisms responsible for the formation of welds without any defects, microstructural refinement, and (2) effects of FSW parameters on resultant microstructure, mechanical, and corrosion properties.

Mechanical And Corrosion Properties

Nd: YAG laser welding of duplex stainless steels as 2205, LDX 2101, 2304, LDX 2404 grades were performed with and without addition materials. As additional material were used Metco 41C high nickel contain powder and 22 9 3 NL filler wire, conventional used for standard duplex stainless steels. The mechanical and corrosion properties of duplex stainless steels welds are dependent on microstructure and chemical composition. The additional materials favourable effects on mechanical properties were observed. The best pitting corrosion resistance were observed at specimens welded with wire addition.
