In the field of mechanical manufacturing, screws serve as critical transmission components, and their wear repair has long been a challenging issue in the industry. Traditional overlay welding repairs for screws result in excessive thermal input, leading to a deformation rate exceeding 15% and requiring substantial subsequent machining. Meanwhile, thermal spray coatings rely solely on mechanical bonding, with a bonding strength of less than 150 MPa, making them highly prone to spalling under heavy-load conditions.
Daodao, the laser cladding equipment, perfectly addresses pain points with its core technological advantages. The device employs a CNC precision control system, with laser power reaching up to 12,000W. The heat-affected zone during the cladding process is minimal, and the deformation after screw repair approaches zero. The coating forms a metallurgical bond with the substrate, achieving a bonding strength exceeding 300MPa. The coating is dense and pore-free, with surface hardness consistently reaching above HRC55.
For severely worn screws, Daokedaowei equipment can apply a 5mm-thick coating in a single pass, directly restoring the original dimensions without extensive post-processing. Compared to traditional methods, it enhances repair efficiency by over 3 times, reduces repair costs to just 1/5 of replacing with new parts, and extends service life to three times the original, making it the preferred solution for screw repair.
