In the field of mechanical manufacturing, screws serve as critical transmission components, and their wear repair remains a significant industry challenge. Traditional overlay welding repairs for screws involve high thermal input, resulting in workpiece deformation rates exceeding 15%, necessitating extensive subsequent machining. Meanwhile, thermal spray coatings achieve only mechanical bonding, with an insufficient bonding strength of less than 150 MPa, making them prone to flaking under heavy-duty operating conditions.
Dowdawo Laser Cladding Equipment Perfectly Resolves Pain Points with Core Technology Advantages. The equipment employs a CNC precision control system, with laser power up to 12,000W. The cladding process features minimal heat-affected zones, and post-repair deformation of screws 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, Daokedaolequipment can apply a 5mm thick coating in a single pass, directly restoring the original dimensions without extensive post-processing. Compared to traditional methods, the repair efficiency is improved by over 3 times, with costs amounting to only 1/5 of replacing the part. The service life is extended to three times the original, making it the preferred solution for screw repair.
