Friction stir welding (FSW) is a solid-state joining procedure that uses a non-consumable tool to join two facing workpieces without melting the workpiece material.
Friction between the revolving tool and the workpiece material produces heat, resulting in a softened zone near the FSW tool.In industry, FSW is primarily used to combine aluminium alloys of all grades, whether cast, rolled, or extruded.
Aluminium alloy butt joints ranging in thickness from 0.3mm to 75mm were successfully connected in a single pass. (dependent on workpiece material, machine power and structural stiffness).Friction stir processing (FSP) is a method of modifying the characteristics of a metal through strong, localised plastic deformation.
The Global Friction Stir Welding Machine market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
PTG Heavy Industries Achieves New Heights in Exotic Alloy Friction Stir Welding PTG Heavy Industries has been recognised as a global pioneer in this revolutionary method of metal joining.
Recent research and development activities at PTG Heavy Industries’ UK headquarters, on the other hand, have expanded the capabilities of the welding specialist’s FSW machines to include the successful joining of exotic steel and titanium alloys that are particularly suited to the stringent requirements of space and aerospace applications.
They have successfully welded aerospace-grade steel alloy and aerospace-grade titanium in thicknesses of 3mm and 8mm, respectively, using their proprietary PTG fixed pin tooling techniques.” Although each presented unique challenges, such as the possibility of workpiece distortion and ensuring adequate heat transfer when blending thicker materials, these issues were overcome.
Friction Stir Welding, patented by TWI (The Welding Institute), is a novel and revolutionary method of joining metals. The technology combines frictional heat with precisely regulated forging pressure to generate extraordinarily high-strength joints with nearly no defects.
Friction Stir Welding changes the parent metal from a solid to a plasticized condition. This happens during a procedure that involves mechanically swirling the materials together to generate a high-integrity, full-penetration welded connection.
