Abstract
A pressure gauge fabricated from directly welded pieces of dissimilar metals. The gauge includes a casing, a tubular socket, and a Bourdon tube. The casing is fabricated of stainless steel and has an aperture with a flange. The socket is fabricated of aluminum bronze and is positioned within the aperture and flange in line contact therewith. The tubular socket also has a bore. The Bourdon tube is fabricated of stainless steel and is positioned within the bore in line contact therewith. Single weld lines exist along the lines of contact between the casing and the socket and between the socket and the Bourdon tube as caused by welding without a filler or insert material operatively associated with the single weld lines.
