摘要
Conical separation discs of thin sheet metal intended for centrifugal separators have, as a rule, spacing members in the form of thin strips welded onto one of their sides. For avoiding local overheating of a separation disc (1), when a strip (2; 13) is to be welded onto the separation disc by roll welding, the strip is formed with at least one ridge (3, 4; 14) extending in the longitudinal direction of the strip, the width of the ridge being substantially smaller than that of the strip (2; 13). Hereby the contact area between the strip and the separation disc will become very small in the welding area, and only a limited amount of energy need to be used for the welding.
