Soldering of brass and stainless steel

The complexity of inseparable connection of these materials increases with increasing thickness of adjacent parts. It is recommended to assemble thin-sheet items by soldering. This eliminates the burnout of zinc from brass, and the connection is sufficiently strong.

Required: brazing conditions

Preheating of brass item by the flame obtained by burning propane mixture should be used. A fusible hard solder should be used and a flux based on potassium fluoride and boric acid should be used. When brazing thick-sheet products, it is recommended to use solders that contain a higher percentage of copper, in particular copper-silver.

Sequence of Operations

Soldering of brass and stainless steel is carried out according to the traditional sequence of transitions. First the parts are cleaned and degreased, then the tools are assembled, followed by brazing with refractory brazing alloys. In critical cases the contact-jet soldering method is used, whereby a compensating steel plate coated with boron is placed under the items to be joined. Supplier Evek GmbH offers to buy brass rolled products of domestic and foreign production at fair price in wide assortment. We provide delivery of products to any point of the continent. The price is optimal.

Welding of brass and stainless steel

Get the seam of complex configuration, moreover, on the thick-sheet structures using soldering impossible. In such situations, welding is carried out under argon. Preheated electric welding with a preheated torch is used. The process is carried out in the following sequence:

• The area of the future weld is briefly heated with an electric arc;
• The arc is brought to operating mode (voltage 20 V, arc length 20 mm), after which the copper additive is introduced into the column;
• The molten additive gradually covered the edge of the brass product, doing it gradually, in steps of 4 ... 5 mm;
• After welding carefully beat off the resulting surface of the weld fine scales of metal.
