Abstract

The end of one solder covered tube is inserted into the end of the other by conically narrowing the first and similarly widening the second, following which an excess pressure of inert gas is applied to the interior of the pipes and soldering is done by localised heat application from outside. In the prefd. practice an excess pressure of gas is applied to start with a effect purging, following which the gas pressure is reduced during the actual soldering operation. The process does away with the need for inert gas furnaces and/or the need for removing flux after soldering.
