Pneumatic cylinders for mechanized multiple spot welding. | Status: Current, Under review

1 Scope This International Standard specifies the requirements of the geometrical and mechanical characteristics of pneumatic cylinders used for multiple spot welding machines and their manufacturing, delivery and test specifications. These cylinders for a nominal air pressure of 1 M Pa (10 bar) are double-acting, with two piston stages in series for the advance during the operational stroke and the force, and a single piston stage for the return.
