RFSSW

01. RFSSW_시스템 필요성

[SPR joint with half-hollow rivet]

[SPR joint with full rivet]

[Clinching]

Conventional joining process for aluminum

· rivet needed

· weight increasing

· sheet thickness depended

· not for high strength eluminum

· high invest for machine and feeding system

· corrosive

· sheet thickness depended

· not for high strength eluminum

· low joining strength joint

Need for alternative

· NO rivet needed

· FOR high strength aluminum

· NO weight increasing

· HIGH corrosion resistance

· NO sheet thickness depending

· LOW invest for machine and feeding system

· HIGH strength performance

· HIGH engergy efficiency

02. RFSSW Corrosion Test

Stack: AW6082-T4 (2mm) and AW6082-T4 (2mm)

03. RFSSW_특징

Characteristics of RFFSW

01 Weight reduction

· without rivet and screws

02 Outstanding performance

· very high welding strength

· very high reproducibility

03 Applications friendly

· For all 5xxx and 6xxx Aluminum in the automobility industries.

· As well as some 2xxx and 7xxx aluminium alloys for aircraft industries

04 High corrosion resistance

· Wetter-Changed-Test and Salt-Spray-Test showed a very high corrosion resistance of the welding
samples

05 Material thickness and joining
direction independ

· Thick in thin and reverse.

· Just depends on overlayer thickness
(up to 3mm oversheet)

06 Very flat finishing surface and
constantly welding nugget

· Facilitate painting work and quality insurance
process
