B . Welding. l) Processes (fusion welding, pressure welding, etc.). z) Methods and instruction in them (rightward, deep penetration, manual, automatic welding, etc .). 3) Welding of metals and alloys other than steel.

4) Filler metals (weldability). 5) Building-up (surfacing) .

Brazing . l) Equipment (installation., blowpipes, et c.). z) Processes (soldering, brazing, bronze welding, etc.). 3) Methods (manual, automatic, furnace , etc.). 4) Brazing of metals and alloys in general. 5) Brazing and fluxes .

C.

Oxygen Cutting . l ) Equipment (installation , blowpipes, etc.). z) Processes (with and without flu x inj ecti on , oxygen-arc, oxygen-gas, oxygen lancing, gouging etc.). 3) Methods (manual, machine) . 4) Cutting of various st eels, metals a nd alloys .

D.

E. Allied Processes . l) H ard surfacing. z) Metal spraying. 3) P ickling.

At its first meetings, the Commission prepared a list of the problems of general interest which it would have t o study . It also attempted to est ablish an order of prio rity for the matter t o be dealt with and the reports t o be prepared; at the top of the list were

powder cutting, building-up, the function of fluxes, economi c questions relating to the oxygen cutting proce3ses, fill er metals for oxy-ac~tylene welding.

Report s on these subj ect s were prepared and discussed . Later, in 1951, I 0 /'l'C 44/SC3 (Welding - Filler met als and electrodes) raised ce rtain problems regarding filler met als; the Commission felt obliged to carry out more fundament – al work in this field and several reports " ·ere prepared and complet ed in 195+ Pa rt of this work is, however, ~till in progre5s and will probably be finished in 1958 at Vienna. In 1954, the Commission decided t o investigat e full y brazing and oxygen cutting. Two Sub-Commissions were formed for this purpose, the first of which has prepared five draft documents which have since been adopt ed by the Com– mission and fo rwarded t o I SO/TC 44. The increasing general interest in metal spraying led , in 1957, t o the fo rma– tion of a Sub-Commission on this subj ect. A 'vorking group has been made responsib!P fo r carrying out a detailed investigation of the different methods of welding at present in use . Commission I may therefore claim that it has succeeded, by dint of constant effo rt, in making progress with the study of problems within its t erms of reference.
