Generally, welding for a specific time will produce acceptable results when:
• The equipment is installed on an automated production line and each station must complete its
process within a certain time limit
• Very small low energy welds on clean components are being made
Welding Temperature: Ultrasonic welding produces a localized temperature rise from
the combined effects of elastic hysteresis, interfacial slip and plastic deformation. The
weld interfaces reach approximately 1/3 the temperatures needed to melt the metals.
Since the temperature does not reach the melting point of the material, the physical
properties of the welded material are preserved. As the ultrasonic welding process is an
exothermic reaction, as welding time increases so does weld temperature.
