Cheeven, as one of the most professional friction stir welding suppliers, is committed to the development, application and promotion of FSW products & friction stir welding technology. Pro in FSW friction stir welding, Cheeven has rich experience in R & D and the production of FSW products, especially in the design and manufacturing of battery trays, electric cabinets, motor products including the electric motor water jacket and aluminium alloy water cooling parts of new energy vehicles. After the production of FSW products, the company will conduct professional ultrasonic nondestructive testing and provide FSW products testing reports.
As one of the leading friction stir welding suppliers, Cheeven has long history of friction stir welding manufacutring and has independently developed additive friction stir welder for sale with upper and lower double heads and intelligent visual friction stir welding technology, which is at the leading level in all the friction stir welding suppliers.
The friction stir welding working principle can be summarized as follow.
1. First both the work plates are clamped together same as in the butt joint. Both plate's weldable surfaces are in contact with one another.
2. Now a rotating tool pin is inserted into workpieces at the interface surfaces until the tool shoulder touched the workpiece. This will deform the material plastically due to heating by friction force. This is a state of the joining process in which, inter-molecular diffusion will deform the material plastically due to heating by friction force.
3. Now the rotating tool is moving forward along the joint line. This will form a joint behind the friction stir welding tool.
4. The tool continuously moves unlit the whole weld is formed. After the joining process, the friction stir welding tool is separated from the workpiece. The hole created by the tool pin remains in the welding plates.
Its work can be clearly understood by the following friction stir welding video.
The microstructure change of the heat-affected zone of the welded joint is small. The residual stress is relatively low, and the welding workpiece is not easy to form.
Large welding seam design, which can be welded in all directions.
The stir welding process is convenient to realize mechanization, low energy consumption and high efficiency.
No need to add welding wire, no need to remove oxide film before welding, no need for protective gas when welding friction stir welding aluminum.
Weldable materials are sensitive to thermal cracks, suitable for welding different materials like friction stir welding of aluminium alloys.
Highly automated. Friction stir processing safety, etc.
Cheever offers all types of friction stir welding products to meet your requirements.
