Abstract

The invention discloses a manufacturing method of a large-diameter laser cladding metallurgical composite pipe, which comprises the following steps: alloy spherical powder is cladded on the inner wall and / or the outer wall of a large-diameter base pipe by adopting a laser cladding process to form a cladding layer, the laser spot adopted by the laser cladding process is a rectangular spot, and the laser power is 5-20kW. The manufacturing method is easy and convenient to implement, the production cost is low, rapid manufacturing of the large-diameter laser cladding metallurgy composite pipe can be achieved, and therefore the manufacturing efficiency is greatly improved.
