echoz Posted January 25, 2011 Posted January 25, 2011 Haha sorry mate, didn't mean to come off as arrogant then, just generally curious cause I've seen a couple different questions from you regarding these disc things I have nothing of use to add to the topic of ultrasonic welding lol, i know how to use a normal welder that you hold in your hand, and I seen a Plasma welder in action on my work experience, but that's the limit of my welding experience Quote
lippydave Posted January 25, 2011 Posted January 25, 2011 Ultrasonic welding between two plastic components will use a sacrificial localised t*t [1](proper engineering term) to provide the material for the weld itself. Instances where I've experienced usage of it in vehicles aren't subject to the v.tight tolerances I imagine you are talking about. It's quite comonly used in IP's (instrument panels) in cars and often with ducts/vents made from multi-part mouldings.... Not saying it can't be done with ultrasonics but IME of it's more generalised application, it won't give you a super low tolerance joint...... HTH [1]New strapline for Bob perhaps? My other toy has sacrificial t**s.... edit:Quick process overview Here Quote
