| LES To. Rm.{William Robotham - Chief Engineer} from HPS.{Horace Percy Smith - Experimental Factory Mgr} 1305 HPS.{Horace Percy Smith - Experimental Factory Mgr}2/VS.{J. Vickers}20.10.37. With reference to the question of Arc Welding arising from the attached Report on the recent visit to Messrs. Daimler. We are surprised to find that Carbon Arc Welding is being used for the torque arms of the front suspension unit, this type of welding being usually reserved for heavy constructional work, boiler making, etc. The chief objection to Carbon Arc Welding lies in the fact that carbon from the electrode is absorbed by the weld and thus produces a very brittle and unreliable joint. It may be, however, that the system is actually Metallic Arc, in which case we agree that the torque arms would be welded more economically and with less distortion than by the usual oxy-acetylene method. The only Arc Welding plant in the Factory is a Philips D.C. Welding Set which was recently supplied and is engaged chiefly on thin gauge sheetmetal details such as exhaust systems, etc. It is, however, quite capable of performing a heavier class of work, and if you have anything in mind in this direction we will arrange for the welding to be carried out on this machine.
