The principle of high-speed laser cladding
2025-01-01
High Speed Laser Cladding (HSLC) is a technique that uses a laser beam to selectively heat a workpiece, creating a molten pool on its surface, which is then rapidly solidified to achieve surface coating and repair. This method enables efficient surface modification of materials while ensuring the base material remains free from deformation.

What are the features of CMT cold metal transfer welding technology?
2025-01-01
By rapidly controlling the wire feed retraction, the molten droplet is separated just before it reaches the workpiece, significantly reducing heat input—by as much as 33% compared to conventional welding. This alternating hot-and-cold process makes the welding procedure gentler, preventing thin plates from burning through or warping, and is particularly well-suited for welding ultra-thin sheets as thin as 0.3 mm.

Classification and Characterization of Protective Coatings for Steel Surfaces
2025-01-01
Organic coatings based on polymer compounds—such as polyester, polyurethane, and epoxy resins—boast excellent chemical resistance and environmental adaptability. Once fully cured, these coatings effectively shield surfaces from moisture, salt spray, and corrosive acid-alkali media, making them particularly well-suited for harsh environments like chemical equipment and marine engineering applications. However, these coatings typically exhibit relatively low mechanical strength, so their impact resistance can be enhanced by applying multiple layers or increasing the coating thickness.
