LargeFSW is a process to join two or more pieces of material to be one. FSW process is the tool runs along the joint seam, intense friction heat is generated due to the wear resistance between the tool and working materials. The heat causes the materials to soften without reaching their melting point. The soften materials of the two joining parts are stiired together and form a solid bonding part after cooling, eliminating the need for any type of additional bonding stuffs.
Breaking away from traditional large profile, but to use the smaller extrusion profile to extend to maximum width. It is not only to be free from regular extrusion limit, but also save the tool cost. We equip with the CNC machine, and can extend the profile width to maximum 1200mm.
Advantages:
- Welding of same or different aluminum alloys without using filler materials (like glues).
- No thermal performance penalty across the welded joint
- No structural change in the materials
- Less weld distortion and shrinkage due to the lower welding temperatures
- Non-porous joint/bond-line
- Homogenous and leak free weld joints
- Economic method for producing very large width heat sinks - by welding smaller low cost heat sink pieces together
