The process of joining metal pieces by the localized application of very high frequency .i.e. ultrasonic frequency ,to the metal pieces held together under pressure is known as ultrasonic welding.
Application : this processs can be used only for the materials upto about 3 mm in thickness ,alought equipment is being developed to extend this range .there is no minimum limit to the sheet thickness that can be welded .ultrasonic welding is excellent for joining thin sheets to ultrasonic welding is particularly adaptable for joining electrical and electronic components ,also in aircraft and missiles .
ultrasonic welding combines pressure and high frequency motion to form a solid- state bond .a transducer which changes the high frequency electrical power into vibratory energy. DM5E ultrasonic thickness gauge
ReplyDeleteUltrasonic welding is a technique whereby high-frequency ultrasonic acoustic vibrations are locally used to workpieces being held together under pressure to create a solid-state weld. It is commonly used for plastics, and especially for joining dissimilar materials. For more welder information check out this >>toolsfocus.com/best-welders-for-beginners
ReplyDeleteAny unprotected exposure to the highly concentrated release of ultraviolet and infrared light emissions from the welding arc can cause such damages. welding helmet guides
