The Structural Engineer, Volume 8, Issue 1, 1930
Sir,- Is there not a demand for a publication of steel details for buildings only(apart from other engineering practice), say a series of loose sheets in, a small portfolio?-taken from drawings with few photographic reproductions and following up-to-date conditions, standardised as much as possible and very little letter press; also dealing with roofs of all types and spans to 100 ft., floors, girders, theatrical conditions, frame buildings, etc., on the lines of the “Practical Exemplar of Architecture,” by Mervyn McCartney.
Readers of The Structural Engineer will be pleased to learn how much interest and attention the very able address by Mr. E. F. Sargeant, to the Yorkshire Branch of the Institution, last year, has attracted. Mr. Sargeant, as Chairman of that Branch, chose as his subject “The Romance of Silica,” and dealt with it in a particularly fascinating manner, as may be judged from the text of his address, which was published in The Structurcrl Engineer for June last. It was, in December, made the subject of an article on the “leader” page of The Times, and we understand that Mr. Sargeant likewise received a highly congratulatory letter from Sir Robert Hadfield in the course of which Sir Robert commented on the amount of time that must have been involved in writing so instructive a paper, which interested him the more in so far as he had himself evolved and invented silicon steel, and expressed his high appreciation of Mr.Sargeant’s own “fascinating and instructive paper.”
Welding has long been considered as the art of uniting pieces of similar metals by ham- mering or compression when raised to a temperature short of the fusing point; but today a broader interpretation must be accepted to include autogenous soldering in which fusion occurs, and any added metal is similar to the pieces to be joined together in firm union. Such autogenous soldering has long been practised with lead. J Caldwell
