Abstract
1,252,016. Making bolts; welding by fusion. STANDARD PRESSED STEEL CO. 18 Dec., 1968 [20 Dec., 1967], No. 60257/68. Headings B3A and B3R. [Also in Division F2] A method of making a bolt or the like comprises providing a stud 10 having a first threaded section 12 spaced from one end of the stud by an abutment shoulder 13 and engaging a nut 20 on the threaded section 12, so that an end face of the nut bears against the shoulder 13. The stud and nut are mechanically worked by conventional equipment to the desired shapes and then heat treated. After heat treatment the threads are formed on the stud and in the bore of the nut. The stud and nut are normally of stainless steel, but two different compatible alloys may be used, the stud at least being of an alloy which develops high strength properties, either by the combination of mechanical working and heat treatment or by mechanical working alone. The stud and nut may be secured by electron beam welding along a length of their threaded engagement to form a weld seam 30. Alternatively, either or both abutting surfaces may be knurled or roughened.
