Powder mix preparation Welding Alloys blend management software provides a list, with quantities of each powder to obtain the required weld metal composition. 3. Powder mixing The powders are mixed to produce a homogeneous blend throughout the batch. Some powders are mixed with binders to prevent segregation and improve weldability. Different mixers are used depending on the wire being produced to prevent cross contamination of elements. 4. Strip forming and powder feeding The strip is formed into a U-shape ready to receive the powder. The strip powder ratio is continuously controlled; the right combination of the strip and the powder is what allows us to obtain the required chemical composition of the weld metal. 5. Wire rolling The wire is closed to form an O-shape (our seamless cored wires are laser butt welded). The wire then goes through the rolling process to reduce the diameter and compact the powder.
