PLPublished on June 20, 1958 OF THE POLISH PEOPLE'S REPUBLIC PATENT DESCRIPTION MZAk tt] £ M No. 40973 KI. 49 h, 25 Instytut Transportu Samochodoirego *) Warsaw, Poland Method of soldering iron with soft solder Patent valid since January 17, 1957 The subject of the invention is a method of soldering cast iron with soft solder. This method, according to the invention, provides a tight joint and is suitable for various connections of cast iron parts, including for the repair of car hulls and heads, it has a particularly wide application in the automotive industry, because the tightness of the connection in this case is a necessary factor. The method according to the invention consists in the fact that the object to be soldered is Firstly, rust, varnish or other contamination is cleaned with a grinder or a file, and then the soldering point is covered with flux, be- •). The owner of the patent stated that the authors of the invention are Eng. Aleksander Jaskiewicz, Eng. Leonard Stepniak, Eng., Ryszard Createdrzynski, and Wieslaw Zychowicz. with a mixture of sodium chloride, e.g. 10 - 25%, zinc chloride, e.g. (50 - 75%) and ammonium chloride, e.g. 10 - 15%, preferably with the composition of about 15% sodium chloride, about 70% zinc chloride and about 15 % of ammonium chloride The soldering point is then heated to a temperature close to the melting point of the solder, i.e. to about 300-400 ° C, in order to remove free carbon from the cast iron surface, among other things, sodium chloride is the main component that influences the carbonization. the soldering points are removed flux residues and covered with a thin layer of solder, consisting of 25 - 75% zinc, 5 - 60% lead and 25 - 50% tin, preferably about 35% zinc about 30% lead and about 35% tin Brazing can be done by all known methods such as: torch, soldering iron, induction, resistance etc. After brazing, the surfaces should be washed with warm water to thoroughly remove the flux. Bad flux removal causes corrosion of the joint. EN
