Abstract

The invention provides a cast pipe build-up welding device and method. The cast pipe build-up welding device comprises a mounting base, a first position adjusting mechanism and a second position adjusting mechanism. The first position adjusting mechanism and the second position adjusting mechanism are oppositely mounted on the two sides of the mounting base, a first welding gun with the adjustableangle is arranged on the first position adjusting mechanism, and a second welding gun with the adjustable angle is arranged on the second position adjusting mechanism. According to the cast pipe build-up welding device and method, by means of the two sets of position adjusting mechanisms and the two sets of welding guns, the first welding gun and the second welding gun are spaced front and back,during welding of the first welding gun, the second welding gun carries out delayed build-up welding on a weld joint, the required build-up welding height is achieved, the delayed welding time of thesecond welding gun is adjusted, heat input in base metal is controlled, and weld joint stacking is facilitated; and the two welding guns are spaced front and back for welding, one-time welding formingcan be achieved, and the welding efficiency of build-up stacking is improved.

Description

technical field [0001] The present invention relates to the technical field of welding, and more specifically, to a cast pipe surfacing welding device and method. Background technique [0002] The cast pipe is a kind of cast pipe fitting. The outer wall of the cast pipe needs to be surfacing to form a positioning ring and a wear-resistant layer. The surfacing welding is a welding method in which metal is melted by electric welding or gas welding and piled on tools or machine parts. However, the current cast pipe surfacing production process uses a gas-shielded welding torch for surfacing welding. At least two laps of surfacing welding are required to achieve the required welding height and thickness, and the surfacing welding efficiency is low. Contents of the invention [0003] (1) Technical problems to be solved [0004] The object of the present invention is to provide a cast pipe surfacing welding device and method to solve the problem of low surfacing welding efficie...
