Realizing technical scheme of the present invention is: a kind of Terahertz TWT slow wave centering welding tool setup, is characterized in that: comprise positioning seat, left locating piece, left locating core, right locating piece, right locating core, briquetting and alignment pin; Described positioning seat is provided with left and right locating rack and interfix frame, and described each locating rack top is provided with locating slot; Described each locating rack there is the briquetting of band locating slot; The adaptation path that described locating rack locating slot, briquetting locating slot are formed in opposite directions contacts with slow wave system, and the axis of each passage is coaxial; Described each briquetting is located by alignment pin; Described left and right locating piece is separately fixed at the left and right sides of positioning seat, and is respectively equipped with left and right locating core; Described left and right locating core is provided with the left and right location core bore can putting into slow wave input, output block respectively; The axis of the passage that described each locating rack locating slot, briquetting locating slot are formed in opposite directions is coaxial with core bore axis, left and right location; When slow wave to be welded input, output block and slow wave stage casing are placed on left and right location core bore and interfix frame locating slot respectively, left and right locating core and slow wave system to be welded coaxial; Slow wave system two welding position lays respectively between left and right locating rack and interfix frame.
Described left and right locating piece is fixed on positioning seat by retention mechanism.
Described left and right locating core is each passed through the through hole of left and right locating piece, and described left and right locating core axially can adjust position in through-holes.
Described left and right locating core is separately fixed on left and right locating piece by retention mechanism.
Described interfix frame is multiple spaced locating racks.
Described interfix frame is preferably three spaced locating racks.
Described multiple spaced interfix frame can be an entirety, and the briquetting matched with interfix frame is also an entirety.
Described each locating rack is connected by retention mechanism with briquetting.
Above-mentioned retention mechanism preferably screw, simple and convenient.
The invention has the beneficial effects as follows: traditional centering mode of wearing centering core bar is changed into and adopts by a ring cylindrical centering clamp, can weld the slow wave system centering of 0.3mm or less internal diameter, after welding, concentricity reaches instructions for use, loads runner pipe electronic beam current passband reach more than 80% with the slow wave of this kind of welding manner welding.
