Abstract

Large items of brass foundry and pipework are formed by stamping and welding, esp. by forming the principal element of the body of the workpiece in two part-spherical halves from a single blank with unilateral or bilateral tubulures and then assembling the two halves by welding. The two part-spherical halves are formed by stamping a flat blank thus providing two roughs having a reserve of metal in their central zone from which the final form of the tubulure is formed by local stamping.
