can improve the strength of welding joint:Ultrasonic impactor makes use of high power ultrasonic to force the instrument toimpact on the metal surface with frequency of 20,000 times/s or more. Metal surfaceinduces great plastic deformation by impacting of ultrasonic with high frequency,high efficiency, high power and great focus on energy. When the originalstress field is affected altered will induce a certain value of compressive stressand the joint of impacted place is made strengthen.Ultrasonic generator connects the transducer inside by cable. Output of transduceris connected with booster. And at end side of booster an impacting needle is installedUltrasonic generator transforms the commercial electric power to A.C of high frequencywith high voltages and transports the current to transducer. The ultrasonictransducer transforms the electric energy to the mechanical energy, which is soundenergy of ultrasonic. Its main evidence is the longitudinal reciprocating expansionmovement. The expansion frequency is equal to the generator's A.C frequencyand expansion amplitude in about 10 microns. One of booster function is enlargethe transducer amplitude exceeding 100 microns. In the other hand, it exertsimpact force full on the needle, force it rushes in high speed. The energy transfersto the welding line after the needle impacting on the work piece to achievethe effect of internal stress elimination. Impacting needle rebounds after receivingthe work piece's reaction, it excites again when it returns to the highfrequency vibrating booster, and it strikes the welding line again. Repeating thiscycle many times it accomplishes the work. CharacteristicHigh power, high impact effectHigh reliability, long using lifeLight weight, portable, easy to operateExcellent designation, wide use scopeDistinctly save energy, reduce charge.
Efficacy1 .Cause residual stress of pulling in the metal welding line surface layer changedinto compressive stress. Significantly increase the fatigue life of metal structure
