    The ideal welded joint obviously is that one in which the properties of the weld metal and the base metal are similar both chemically and physically. Although at the present time this objective does not seem commercially attainable, such an ideal should be kept constantly in mind and investigation pointed in that direction. In the light of available information the choice of materials for welding apparently does not depend so much upon the process employed as upon welding technique and the careful control of contributing factors such as temperature and pressure, in the case of plastic welding; speed and current density, in the case of electric welding; kind of flame and its proper manipulation, in the case of gas welding flux used, etc. It is not possible to definitely define all the factors which influence weldability and the statement in some specifications that steel shall be of good weldable quality leaves the manufacture in somewhat of a quandary. Subcommittee XXI on Steel for Welding of the Society's Committee A-1 on Steel passed a motion about a year ago with respect to plate material for fusion welding, which was slightly amended January 15, 1931, to read as follows: 1. It was voted that it is not necessary at present to write separate and complete specifications for steel for fusion welding in view of the number of standard specifications under which satisfactory material has been purchased for this purpose. 2. It was voted as the opinion of the committee that steel made under the following A.S.T.M. specifications can be welded satisfactorily by the usual fusion processes now in general use: A 7-29 Structural Steel for Bridges A 9-29 Structural Steel for Buildings A 113 — 29 Structural Steel for Locomotives and Cars A 12-21 Structural Steel for Ships A 30-24 Boiler and Firebox Steel for Locomotives A 70-27 Boiler and Firebox Steel for Stationary Service A 78-30 Steel Plates of Structural Quality for Forge Welding A 89-30 Steel Plates of Flange and Firebox Quality for Forge Welding A 83-30 Lap-Welded and Seamless Steel and Lap-Welded Iron Boiler Tubes A 53-30 Welded and Seamless Steel Pipe (with carbon restriction) A 82-27 Cold-Drawn Steel Wire for Concrete Reinforcement A 106-29 Lap-Welded and Seamless Steel Pipe for High-Temperature Service A 129 — 30 T Open-Hearth Iron Plates of Flange Quality A 120-28 T Black and Hot-Dipped Zinc-Coated (Galvanized) Welded and Seamless Steel Pipe for Ordinary Uses
