Processing technology and quality inspection standards for titanium stirrers

High quality titanium mixers rely on mature forging, welding, precision machining, and anti-corrosion processes. Poor quality titanium mixers are prone to problems such as weld corrosion, shaft bending, blade deformation, and impure materials, which seriously affect the stable operation of the production line. The production of regular titanium mixers must strictly follow the complete process of material verification, precision machining, non-destructive testing, acid washing and passivation.

The raw materials are made of national standard TA2/TA10 grade one titanium material, which undergoes spectral testing upon arrival at the factory to eliminate recycled and impurity materials; The mixing shaft adopts precision grinding and straightening technology, with high coaxiality and smooth operation; The blade is precision welded using argon arc welding, with a full weld seam and no porosity or slag inclusion. After welding, the entire blade undergoes stress relief treatment to prevent long-term stress corrosion cracking. The finished product undergoes PT penetrant testing, full appearance inspection, and dimensional review to ensure no cracks or defects.

Finally, a unified acid pickling and passivation treatment is carried out to remove the surface oxide layer, form a stable anti-corrosion protective film, and improve the corrosion resistance and material cleanliness. All titanium mixing devices of Shaanxi Qianyi Tuoda can provide material reports, flaw detection reports, and process traceability data, supporting non-standard customization, on-site surveying, and bulk supply, providing long-term anti-corrosion mixing solutions for chemical, new energy, and pharmaceutical enterprises.
