The Q235D multilayer laser cladding with Febased alloy powder was carried out. We concluded that the cladding layers we obtained are smoother, and cladding metallurgical bonding layer is better, and no crack and almost no hole appear. It is found that the hardness of the whole cladding lasers has been affected much by using different time interval. If the time interval is very short, the hardness of the whole cladding lasers will reduce with the increase in number of cladding layer. And the hardness of the first cladding layer is the highest of all the cladding layers. The hardness of the cladding layer is decreasing gradually from the first cladding layer to the last. The hardness of the last cladding layer is the lowest. If the time interval is long, the hardness of the whole cladding lasers will reduce similarly with the increase in number of cladding layer. But the difference compared with the last way is that the hardness of the first cladding layer is the lowest of all the cladding layers. The hardness of the cladding layer is increasing gradually from the first cladding layer to the last. The hardness of the last cladding layer is the highest.
