Abstract The use of laser welding of thermoplastics is increasing in a broad range of applications due to the many advantages it has over competing methods. It can be used in both surface heating and through transmission laser welding. In some applications, it is desirable to laser weld optically clear thermoplastics to each other. This is easier to accomplish with surface … [Read more...] about Overview of Methods for Laser Welding Optically Clear Plastics

Carbon Black Selection for Successful Through Transmission Laser Welding and Joining
by Scott Sabreen, The Sabreen Group, Inc., and Avraham Benatar, Plastics and Composites Joining Laboratory, Welding Engineering Program, Department of Materials Science and Engineering, The Ohio State University Abstract Laser welding is used in a wide range of applications to join thermoplastics because it is a noncontact heating method with short cycle times and lower cost. … [Read more...] about Carbon Black Selection for Successful Through Transmission Laser Welding and Joining
Utilizing Dynamic Hold Capability of Servo-Driven Ultrasonic Welders
by Alex Savitski, Ph.D.; Hardik Pathak; Leo Klinstein; Kenneth Holt; and David Cermak; Dukane IAS, LLC Ultrasonic welding of thermoplastics is widely used by many industries to fuse together two parts in a short time without introducing additional consumables, such as fasteners, adhesives or solvents. The recent development of servo-driven ultrasonic welders introduces … [Read more...] about Utilizing Dynamic Hold Capability of Servo-Driven Ultrasonic Welders
3D-Printed Plastic Parts: To Weld or Not to Weld?
by Trevor Larcheveque, Branson Ultrasonics Corp. 3D printing (3DP) now is widely adopted for prototyping and developing new product designs because it allows plastic component and part prototypes to be developed, produced, assessed and modified far more quickly and economically than traditional injection-molded plastic parts, which require significant up-front investment in … [Read more...] about 3D-Printed Plastic Parts: To Weld or Not to Weld?
