Abstract
Bourdon tubing is constructed from metal strip by roll forming the strip into a desired tubular cross section with the opposed edges abutting longitudinally at a location in the cross section at which contemplated operational stresses are predetermined to be relatively low. After continuously welding the edges in a pressure-tight relation, the tubing can be shaped along its length into a Bourdon tube configuration without need for further metallurgical mill processing.
