Features of brass welding with argon
Welded joints of brass by conventional methods is not possible because at elevated temperatures the surface of products formed intense oxide film that prevents welding. In addition, when heating the brass to the melting points begin to form volatile gaseous compounds of zinc, which are hazardous to human health. Another technological difficulty is that at high temperature the brass in the range of 300…4500 With all alloys are prone to cracking.
For high-quality welding requires the use of special welding fluxes, which prevent the access of oxygen to the zone of formation of the weld. The filler material is more commonly used brass alloy wire, which contain a higher percentage of silicon. As a result, not only increase the strength characteristics, but also eliminates the burning of zinc. With the same purpose in welding using «short arc», with a length of not more than 15 mm, and a voltage not exceeding 25 V.
Buy semi-finished products and billets of brass of various brands at the best price from the manufacturer, the company offers Electrocentury-steel. The provider ensures timely delivery of goods to the point specified by the customer.
The sequence of welding argon of brass
High-quality welding is possible if consistently implement the following transitions:
- Carefully prepare the edges of connected products. Kind of cutting is determined by the thickness of parts: if it does not exceed 1…1,5 mm, that performs flanging of the edges, with thickness up to 5 mm 0 to the unilateral cutting, for thicker workpieces it is necessary to make an X-shaped preparation;
- Edges, in addition to Stripping is subjected to the processing in concentrated sulfuric acid, which most efficiently removes all contaminations;
- Welding should only be exposed to well dried billet;
- Argon flow in the zone of formation of the weld must be performed with the flow rate not below 100…110 DM3/h per 1 mm of the weld, with the formation of the weld it is desirable to perform a burner nozzle which is located perpendicular to the welded surfaces.
The company Electrocentury-scald offers at affordable prices from the manufacturer of a variety of rolled and welded construction, made of various brass alloys. The provider ensures timely delivery of products in the item set by the user.
