The Safty Operation of Ultrasonic Welding 


Hazards of ultrasonic welding include exposure to high heat levels and voltages. This equipment should be operated using the safety guidelines provided by the manufacturer to avoid injury. For instance, operators must never place hands or arms near the welding tip when the machine is activated.Also, operators should be provided with hearing protection and safety glasses. Operators should be informed of government agency regulations for the ultrasonic welding equipment and these regulations should be enforced.


Ultrasonic welding machines require routine maintenance and inspection. Panel doors, housing covers and protective guards may need to be removed for maintenance.This should be done when the power to the equipment is off and only by the trained professional servicing the machine.

Sub-harmonic vibrations, which can create annoying audible noise, may be caused in larger parts near the machine due to the ultrasonic welding frequency.This noise can be damped by clamping these large parts at one or more locations. Also, high-powered welders with frequencies of 15 kHz and 20 kHz typically emit a potentially damaging high-pitched squeal in the range of human hearing. Shielding this radiating sound can be done using an acoustic enclosure.
