Described left and right locating piece is fixed on the positioning seat by retention mechanism.
Described left and right location core passes the through hole of left and right locating piece respectively, and described left and right location core can axially be adjusted the position in through hole.
Described left and right location core is separately fixed on the left and right locating piece by retention mechanism.
Described interfix frame is a plurality of spaced locating racks.
Described interfix frame is preferably three spaced locating racks.
Described a plurality of spaced interfix frame can be an integral body, and the briquetting that matches with the interfix frame also is an integral body.
Described each locating rack is connected by retention mechanism with briquetting.
Above-mentioned retention mechanism is screw preferably, and is simple and convenient.
The invention has the beneficial effects as follows: with traditional centering mode of wearing the centering core bar change into adopt pass through between ring cylindrical centering anchor clamps, can be to the slow wave system centering welding of 0.3mm or littler internal diameter, welding back concentricity reaches instructions for use, reaches more than 80% with the slow wave of this kind welding manner welding runner pipe electronic beam current passband of packing into.
