Ultrasonic Welding Machine | Ultrasonic Plastic Welding | Ultrasonic Welding Basics

Ultrasonic Welding: Ultrasonic welding is represented as a friction welding method, where oxides and other contaminants present on the material surfaces are broken up and also the components to be welded are brought together under simultaneous pressure. Molecular bonding, just like the conventional cold-press welding, then takes place. Ultrasonic welding is the conversion of high…

Ultrasonic Welding: The human ear can hear mechanical vibrations in the frequency range of 16 Hz to 16 KHz. Inaudible frequencies below 16 Hz are known as infrasound and those between 16 KHz and 100 GHz are known as ultrasound. Frequencies above 100 GHZ are known as hyper sound. The process is “green” in that…

LASER Beam Welding | LASER Cutting System

Laser Beam Welding: Definition: Laser beam welding is a welding process that uses a laser beam to melt and vaporizes a material. LASER (Light Amplification by Stimulated Emission of Radiation) beams are very high energy density electromagnetic beams which are highly coherent, monochromic and unidirectional. Power of LASER: For example, a LASER can give a…

Pressure Thermite Welding | Thermite Welding Process

Pressure Thermit Welding: Pressure thermit welding is a process in which the heat produced by the thermit reaction is utilized only for heating the ends of the pieces to be joined, while the actual joint formation occurs by solid pressure welding. History of Thermit welding: In 1893 Hans Goldschmidt of Germany began to experiment with…
