4047 AlSi12 Flux cored aluminum soldering wire

The manufacturing process control of 4047 AlSi12 Flux cored aluminum soldering wire
 is very strict. Because the molten metal comes from the steel sheet skin and the ingredients contained in the flux, the dimensions and chemical components before manufacturing need to be checked in detail to ensure quality. Because the internal space of the welding material of the 4047 AlSi12 Flux cored aluminum soldering wire is limited, the size of the flux particles becomes more important, and the particles form a bird's nest-like bond, and the flux composition elements are not uniform.


 
Most of the 4047 AlSi12 Flux cored aluminum soldering wire is rolled into a U-shaped section by a flat metal sheet strip. The granular flux is filled in the U-shaped metal groove and then sealed and rolled. It is pressed into the tube-shaped welding wire, and the rolled wire is rolled into a tube-shaped wire to obtain the required wire diameter through a series of drawing operations. This drawing operation can also make the filled flux uniformly fixed in the wire leather. How to prevent some wires from forming hollow (without flux) in the 4047 AlSi12 Flux cored aluminum soldering wire due to poor control during the manufacturing / production process is the key to the quality of the flux cored wire. In addition, the surface of the 4047 AlSi12 Flux cored aluminum soldering wire should also be smooth and clean, otherwise it will affect the smoothness of wire feeding and the rapid transmission of welding current. 4047 aluminum flux-cored wire is packaged in rolls or barrels to avoid entanglement or breakage of the wires. Usually, the coiled wire is encapsulated with a plastic sleeve and a desiccant is placed to avoid moisture. Feed out of the paper cassette. When the skin is thicker, the cross section is mostly the butt (BUTT) method and the amount of welding is small. Most carbon steels and low-alloy steels have wire shapes of 2.8 mm and below. When the alloy and the wire diameter are large, a large space is required in the wire to contain the cross-section shape of the flux and the alloy element in a overlapping or heart-shaped connection.
