Friction Stir Welding (FSW)

Saldatura a frizione (FSW) is an advanced solid-phase welding technology. The heat input during welding is small, the metal does not melt, and there is no elemental burnout. For a high-quality connection of metal materials such as aluminum, magnesium, steel, titanium, and metal matrix composite materials.

Uniaxial shoulder mixer

Friction stir welding tool (mixing head) is one of the core technologies to realize friction stir welding, which is known as the "heart" of friction stir welding. As a professional mixing head manufacturer, we have a high-level mixing head design team, advanced production, and processing equipment, and leading heat treatment and testing technology. In view of different materials, thicknesses and welding methods, our company have successfully developed a variety of specifications and a series of mixing heads.

Standardization and serialization of mixing head

After years of process exploration and accumulation, our company has standardized hundreds of mixing heads, which are suitable for welding all series of aluminum alloy, magnesium alloy, copper alloy, as well as some brands of high-temperature alloy steel and titanium alloy materials; the weld forms include flat straight seam, plane two-dimensional, cylinder circular seam, cylinder longitudinal seam, space curved seam, intersecting line and other welds; the welding forms include butt joint, lap joint, etc Welding, butt joint, unequal thickness welding, double-sided welding, angle welding, and other welding forms.

The standardized mixing head is a batch mixing head developed for mass use in the market. Its main customers are long-term stable welding products. The change of product structure does not affect the use of the mixing head, and the use conditions do not change significantly. The typical application fields of standardized mixing head include: new energy vehicle parts (battery tray, battery pack, water-cooled plate, radiator, hub), rail train (vehicle body, sidewall, floor, roof, sleeper beam, coupler plate, etc.), power electronics (fin radiator, liquid-cooled radiator, heat sink, etc.)
