A truss welding process

Abstract

The invention discloses a truss welding frock technology. The technology comprises the steps of making an upper chord and a lower chord incline at 45 degrees through a locating wall block, conductingspot welding on the upper chord and the lower chord until full-length welding is completed for the upper chord, pushing a bottom board to be in place from the bottom, meanwhile making half of a locating wall plate vertical, locating and welding big and small angle steel at the head, welding the bottom plate and box iron of the bottom plate, hoisting and locating the upper and lower chords of a right monolithic, locating and conducting spot welding on a stand rod, locating and conducting spot welding on an angling strut, hoisting an upper flat layer section of a truss in a gantry welding deviceand locating the upper flat layer section, hoisting a straight line left monolithic in the gantry welding device and locating the straight line left monolithic, aligning a middle opening closely nextto an upper-side plate end and conducting spot welding on the middle opening, getting the middle opening into shape through a caliper, welding the straight line bottom plate and the box iron, locating and conducting spot welding on an apron board end and a guide track support plate end, locating and conducting spot welding on a support rod at an inflection point, and locating and conducting full-length welding on all three faces at the inner side of a rear inflection point. The truss welding frock technology has the advantages of being simple in structure and high in practicability.

Description

technical field [0001] The invention relates to a truss welding tool, in particular to a truss welding process. Background technique [0002] In general, the truss welding tooling in the industry is welded in one piece, and then the upper gantry is assembled. The flatness of the single piece and the deformation of the long-span truss after assembly cannot be controlled, which is a problem in this industry. Contents of the invention [0003] The purpose of the present invention is to solve the above problems, and a welding process of truss is designed. [0004] To achieve the above object, the technical solution of the present invention is a welding process of a truss, comprising the following steps: [0005] (1) Put the upper chord and the lower chord on the welding tool, and the upper chord and the lower chord are tilted 45° by positioning the wall block; [0006] (2) The positioning pin used to locate the height direction of the upper chord and the lower chord is pushe...
