High frequency pipe bending
Web1 de jun. de 2010 · The solid-state weld process uses less heat input because high-frequency (150-400 kHz) electromagnetic energy is used in conjunction with high pressure to join two materials. The material is joined under heat and pressure instead of melted together with a filler material. Controlling key welding process parameters, such as … WebHigh frequency vibrations are considered more dangerous. FIGURE 3. Stresses in the vibrating pipe sections. In order to dispel those doubts, a straight section of a pipe with a diameter of d=273 mm and a length of l=9 m supported on both ends is considered. The amplitude of the vibration velocity of the pipe's centre of mass is A=200 mm·s-1.
