How Daokedao Laser Cladding Equipment Reduces Heat-Affected Zone for Precision Parts
For precision parts, the heat-affected zone (HAZ) generated during the laser cladding process is an important factor affecting the part's precision and performance. Too large a heat-affected zone will cause deformation of the part, resulting in scrap. Daokedao's laser cladding equipment adopts advanced ultra-fast cooling technology and pulse laser technology, which can effectively reduce the heat-affected zone. The ultra-fast cooling system can quickly cool the cladding area after cladding, reducing the heat conduction to the surrounding area of the part; the pulse laser technology controls the laser energy output in the form of pulses, reducing the continuous heat input to the part. The heat-affected zone width of Daokedao's laser cladding equipment is less than 0.5mm, which is 50% smaller than that of similar products on the market. This technology makes the equipment especially suitable for the cladding repair and surface strengthening of precision parts such as aerospace components, precision molds and electronic parts. For example, when cladding precision electronic connectors, the small heat-affected zone ensures that the internal structure of the connector is not damaged, and the dimensional precision of the part is maintained. Daokedao's ultra-fast cooling and pulse laser technology have been verified by a number of authoritative institutions, and the cladding effect has reached the international advanced level.
