Reduce Residual Stress with iQ Servo Ultrasonic Welder

Even on parts with good weld strength, failure can occur in the field due to residual stresses [A].  With ultrasonic welding, residual stresses are typically in the range of 35 MPa due to the rapid cooling of the small amount of melt [A, B].  Recent experimentation at Turku University of Applied Sciences in Finland have… Continue Reading Reduce Residual Stress with iQ Servo Ultrasonic Welder

What Happened to Your Ultrasonic Weld Quality?

The most important factor in troubleshooting problems in ultrasonic welding is understanding the fundamentals of the process. With this basic knowledge, most problems can be easily diagnosed and resolved. Even so, sometimes your time-tested weld recipe may suddenly fail for no discernible reason. Perhaps your ultrasonic welder has been running the same application for months,… Continue Reading What Happened to Your Ultrasonic Weld Quality?
