What do Austins weld like this? 64 VICTORIA STREET, WESTMINSTER, LONDON, S.W.1. JMS/FP.{F. Potts} 5th October 1936. Messrs. Rolls-Royce Limited, D E R B Y. Your Ref. Hs{Lord Ernest Hives - Chair}/Gry{Shadwell Grylls}/4/KW. Experimental Dept. Dear Sirs, We thank you for your letter of the 1st October regarding the manufacture of Rear Axle Tubes and the Butt Welding operation on the flange to the tube of 5" dia. x 3/16" thickness. We would advise you that while we do not undertake the actual welding in production quantities of these Axles as we are manufacturers of the Welding Equipment only, we are in a position to forward full particulars of a suitable Automatic Flash Welding Machine for this purpose. It may interest you to know that we have supplied machines to Messrs. Austin Motors and the Ford Motor Co, etc, for the welding of their Rear Axle Tubes and in every case a highly satisfactory performance has been obtained by our customers from these machines. As you are probably aware the use of Automatic Flash Welding enables this assembly operation to be carried out at a minimum cost and on the particular size you mention, viz;- 5" dia. tube having a sectional area of approximately 2.8 sq.inches, the actual welding time would be 20 seconds, and for a consumption of one KW hour (B.O.T.U.) 8 welds could be obtained. We are enclosing herewith Photograph No.432 shewing a machine we have installed at the Ford Motor Co, for a p.t.o. | ||
