AbstractThe surface strengthening of ball valves faces challenges such as high dilution rate and grain coarsening. However, high-speed laser cladding (HSLC) reduces dilution rate by reducing heat input through high scanning rate, and refines grain size through rapid cooling. Therefore, in this work, WC composite coating was prepared on the surface ...

Disadvantages of side axis powder feeding technology1. The selection of metal powder is limitedDue to the lack of protective gas, the laser melt pool can only rely on the self-protection of the molten slag during the melting of the overlay powder. Therefore, in current industrial production, self melting alloy powder is often used in the side axis ...

1. Laser powerPower directly affects the amount of melted powder and coating efficiency per unit time. When other working parameters are determined, low power may result in incomplete powder melting, pitting after polishing, insufficient bonding force, and low coating hardness; If the power is too high, it may be due to excessive melting of the mel...

Fault in the fiber optic section1. Fiber breakage: Fiber breakage is the most common situation in fiber laser machine failures, usually occurring in fibers that have been in use for a long time or have been excessively bent. The solution is to replace the fiber with a new one.2. Fiber optic pollution: When the surface of the fiber optic cable is co...

1、 Waterway inspectionThe main reason for abnormal water flow in the laser is due to water blockage or pump failure. Therefore, we first need to check whether the water path of the laser is blocked and whether it is well connected. If there is a blockage in the waterway, it is necessary to clean or replace the local water pipe and exhaust it. If th...

Laser cladding, also known as laser surface strengthening treatment or laser coating technology, is an advanced material surface modification technology that rapidly melts metal or non-metal powder on the surface of a workpiece through high-energy laser beams, and then cools and solidifies to form a layer of coating with specific properties. This t...

The causes of cracksDuring the fusion process, the high-energy laser beam rapidly heats up, causing a significant temperature gradient between the fusion layer and the substrate. In the subsequent cooling, the volume of the cladding layer and the substrate is inconsistent, which constrains each other and generates stress.During the growth process ...
