- Brief description
- Series of laser welds in amorphous PET
- Keywords
- laser, laser-weld, polyethylene (PE), polyethylene terephthalate (PET), polymer , weld
- Categories
- Polymer
- System
- Polyethylene terephthalate (PET)
- Composition
- Amorphous polyethylene terephthalate (APET)
- Standard codes
- Reaction
- Processing
- Applications
- Laser welding is a rapid, sterile, technique for joining polymers. It is, however, restricted to lap joints and to certain polymer types.
- Sample preparation
- Technique
- Cross-polarised light microscopy
- Length bar
- 12 mm
- Further information
- A 900 Watt IR laser (940nm wavelength) with a beam spread of 10mm was used to form lap joints between 0.5mm thick sheets of amorphous polyethylene terephthalate (APET). Different raster rates have been used: 5, 10, 25, 40 and 60 m/min from top to bottom.
