21Ultrasonic welding — is an industrial whereby high frequency ultrasonic acoustic vibrations are locally applied to workpieces being held together under pressure to create a solid state weld. It is commonly used for plastics, and especially for joining dissimilar… …
22Friction stir welding — (FSW) is a solid state joining process (meaning the metal is not melted during the process) and is used for applications where the original metal characteristics must remain unchanged as far as possible. This process is primarily used on aluminum …
23Breathing gas — is a mixture of gaseous chemical elements and compounds used for respiration. Air is the most common and only natural breathing gas. Other artificial gases, either pure gases or mixtures of gases, are used in breathing equipment and enclosed… …
24Electrogas welding — (EGW) is a continuous vertical position arc welding process developed in 1961, in which an arc is struck between a consumable electrode and the workpiece. A shielding gas is sometimes used, but pressure is not applied. A major difference between… …
