Welding steel with brass
Buy equipment, consumables and finished welded structures from various brands of brass with steels is offered by Electrovek-Steel. Economically reasonable prices are from the manufacturer. The supplier ensures timely delivery of products to the point determined by the customer.
Methods of manual welding of brass and steel products
The choice of welding technology is determined by the brands of brass and steel, as well as the type of welding electrodes. In any case, only electric welding is used, in which the mechanical parameters in the zone of the formed weld are the most uniform.
For manual welding, carbon electrodes and fluxes are used, and those that contain phosphorus are excluded from the list of additive materials. Manual welding is used primarily for brass, which contains an increased percentage of copper, and the presence of zinc is limited to 18−18%. With an increase in the amount of zinc, the wetting conditions of the melt deteriorate, as a result of which the seam is obtained intermittently, and the formation of scaly folds with increased brittleness is possible along its edges. As additives, wire made of tin-lead bronze is used. The bevels on the edges on the brass side are not met.
Electrovek-steel company proposes to buy consumables and accessories for the work on manual and mechanized electric welding of brass and steel. The delivery is carried out at economically favorable prices of the manufacturer. The supplier provides delivery of products to the address specified by the consumer.
Mechanized electric welding of steel and brass
With the use of semi-automatic welding machines, two technologies have been applied:
- Welding with copper electrodes containing surface coatings of siliceous-manganese bronze;
- Welding with non-consumable tungsten electrodes.
The first method is effective for brass, which contains from 85% copper. The mechanical strength of the joint is in the range 280… 320 MPa, with a bending angle without cracking of not less than 170 0. Welding under a layer of flux using tungsten electrodes is more effective, since it has no restrictions on the brands of brass, and the welded joint has a tensile strength of 340… 360 MPa, with an allowable bending angle of 160… 170 0. The arc is directed mainly at the brass edges, and to improve the quality and accuracy of the weld, the process is carried out at an arc length of not more than 15… 18 mm.
Buy ready welded structures and semi-finished products, welded from brass and steel of various grades offers the company Elektrovek-steel. Effective prices of the manufacturer. The supplier guarantees the prompt delivery of products to the point specified by the customer.
