@bassman7530. Foam earplugs may be ok as long as the decibels dont get to high the last time it was tested in the small room where I work it was round 120decibels and with my earmuffs on I could bearly hear it yet it was able to be heard in most other parts of the factory . I also work with welder for long shifts (8 hours) at some points up to 5 days a week . we get our hearing tested yearly and so far I have had no loss.
@ Franky it's vibration . The horn puts pressure on the part to what ever psi you have it set heat is caused by amplitued for what ever you set the weld time to then hold time and horn resets to start position. And yes it can be very loud depending on what you are welding I use that type of machine daily (same brand). Grade 5 earmuffs must be worn at all times to prevent hearing loss.
@coffebug You seem fairly knowledgable on ultrasonic welders, so I'd like to ask you a question. How efficiently will Grade 5 earmuffs reduce the volume you perceive in decibels? I do assembly in a factory and am required to use ultrasonic welders occasionally, and the standard hearing protection my plant offers is foam earplugs which reduce noise by about 30 decibels. Is that insufficient protection for such high-frequency pitches when working with an ultrasonic welder for a 9 hour shift?
thank you for adding in the tid bit about them rubbing together. I have been looking for info on how ultrasonic welding works and you are the only one to tell me.
@jarjarbinx79 most likely MHz... 4.5 KHz is in the middle of the audible range so it's not even ultrasound, and probably couldn't produce enough heat from friction to do this.
his voice reminds me of star wars :D

how does it move... back and forth? side to side? or is it vibration? up and down?

lol - "it's 4.5" - "sooooo.........?"
These machines aren't that bad to work with when you have hearing protection, you can barely hear them.

That sound would drive me nuts after a few welds.

Judgeing by the size of the horn, I would guess that it's a 20KHz machine.
xrayrep 3 years ago
Correct!
Its a Rinco Ultrasonic AG 20kHz benchwelder.

well as usual, the fatal mistake was in omitting units. Maybe he means the machine tip moves at 4.5 cycles per second?
MR9966 3 years ago
Wrong!
Its a stroke depth scale that is set on 4,5mm. It means the machine is set to make a maximum stroke of 4,5mm.
Renzoisdera 3 years ago
Could be in inches too.
Renzoisdera 3 years ago
@MR9966 that would most likely be 4.5 KHz. that means 4.5 thousand per second. 4.5 cycles would be a simple beat that is useless.

this guy doesnt have any idea of how the thing works. "so, how many times did it move?" ; "4.5"

no, but the sound it made was about 10-15 khz
