Rotation friction welding |
|---|
Description of welding method |
The joining areas of the rotation symmetric plastic pieces are pressed together and brought into a rotating motion to each other. The input of heat is performed by friction losses in the contact zone. The plastic pieces cool down under pressure or way-limited until the melt is resolidified. Weld fillers are not needed. |
Vibration friction welding |
|---|
Description of welding method |
The joining areas of the plastic pieces are pressed together and brought into an oscillating motion to each other. This oscillating motion can be modulated in a linear, orbital or radial manner with adjustable amplitude. The input of heat is performed by friction losses in the contact zone. The plastic pieces cool down under pressure or way-limited until the melt is resolidified. Weld fillers are not needed. |
Induction welding |
|---|
Description of welding method |
Ferromagnetic electric circuits are included in the joining areas of the plastic pieces, the plastic pieces are pressed together and exposed to an electromagnetic field. The input of heat is performed by electric losses within the ferromagnetic electric circuit. The plastic pieces cool down under pressure or way-limited until the melt is resolidified. Additional welding material is needed in form of ferromagnetic carriers. |
High frequency welding |
|---|
Description of welding method |
The joining areas of the plastic pieces with dielectric features are pressed together and exposed to an electromagnetic field of high frequency. The input of heat is performed by dielectric losses in the basic material. The plastic pieces cool down under pressure or way-limited until the melt is resolidified. Weld fillers are not needed. |
Microwave welding |
|---|
Description of welding method |
The joining areas of the plastic pieces with dielectric features are pressed together and exposed to a microwave field. The input of heat is performed by phase displacements and effects of polarisation causing energy losses in the basic material. The plastic pieces cool down under pressure or way-limited until the melt is resolidified. Weld fillers are not needed. |
Ultrasonic welding |
|---|
Description of welding method |
The joining areas of the plastic pieces with energy directors are pressed onto each other and ultrasonic is inserted. The input of heat is performed by friction losses in the energy director. The plastic pieces cool down under pressure or way-limited until the melt is resolidified. |
