TO state that it has hithert6 been impossible to weld together ferrous and non-ferrous metals, notably steel and aluminium, is not strictly correct, but it-is hardly beyond the truth to describe the practicability of such an operation as having been of a somewhat doubtful nature. Now, however, it is claimed by Barimar, Ltd., 14-18, . Lamb's Conduit Street, London, W.C.1, that it can successfully _accomplish the operation.
This concern, a few years ago, intro
• duced a process for welding steel to cast iron, and such satisfactory results were achieved from this that intensive research in the extension of the scheme to ferrous and non-ferrous metals was .embarked upon. The culmination Of these experiments and investigations. is represented by this latest scientific welding development.
Whilst this new Barimar process is complex, it must not be confused with any form of brazing or soldering. The joining of the metals is a genuine weld. There is, we understand, a fusive union
of such strength that the yield point of the joint is no lower than that of the weaker metal.
It is to a number of factors that the company attributes the success of the process. Among these may be named as points upon which the development is dependent a new 'form of flux, unusual methods and technique of manipulation and extremely accurate flame control.
Already the new process -is being applied, by Barimar, Ltd., to work of great importance, and there is no shadow of doubt that, if the good promise shown be fulfilled, there will be innumerable fields for its employment not only in repair work but also in manufacture. Moreover, these will be by no means limited to the automobile industry. Emphasis of the importance of this development is indeed unnecessary.
