Abstract
The invention belongs to a radioactive goods transportation container manufacturing process and particularly relates to a VVER fuel assembly transportation container manufacturing welding process. The fuel assembly transportation container manufacturing welding process comprises the following steps: (1) grouping support components in a support grouping tool, (2) welding supports, (3) welding a seamless pipe to a flange to form a positioning pipe, (4) grouping the positioning pipe which is well welded and the support which is well welded in a shell body welding clamp, (5) welding the positioning pipe to the support, and (6) examining the welding. The fuel assembly transportation container manufacturing welding process has the advantages that through using the fuel assembly transportation container manufacturing welding process, welding deformation can be effectively guaranteed in a controllable range, and the quality of assembly is finally guaranteed.
Description
Technical field
The invention belongs to a kind of radioactive substance cask manufacturing process, be specifically related to a kind of VVER fuel assembly cask and make welding procedure.
Background technology
VVER fuel assembly cask is applied to the transportation of gulf, field s Nuclear Plant transportation, this assembly is hexagon, approximate circle, adopt seamless steel pipe as the cask shell, two ends add the container casing of flange flat cover sealing, for ease of transportation, two autonomous container assembly weldings arranged side by side are integral on two bearings.
The centre that damping and supporting role have been arranged between housing inner assembly and housing is the wooden tubular liner of hexagon inner chamber, detects the liner cavity floor after assembling with respect to the flatness of pan straddle bottom surface.For lifting, convenient fixing, be welded with hanger and alignment pin.The inside and outside no-movable part of container, simple for structure, two container tube are longer, and form and position tolerance, linearity are had relatively high expectations, and wall thickness is thicker, weld yieldingly, and is difficult for proofreading and correct, and linearity is difficult for assurance, affects packing into of liner.
Therefore, controlled for the welding deformation that guarantees this structure, assembly precision is controlled, need dimensional accuracy and structural strength after a complete effective welding procedure of cover guarantees to make, guarantee radioactive substance cask workmanship.
Summary of the invention
The purpose of this invention is to provide a kind of dimensional accuracy and structural strength after guaranteeing to make, guarantee that the fuel assembly cask of radioactive substance cask workmanship is made welding procedure.
The present invention is achieved in that a kind of fuel assembly cask manufacturing welding procedure, comprises the steps,
(1) bracket component is grouping in to frock in the support group;
(2) welding support;
(3) seamless pipe is become the positioning pipe welding with flange welding;
(4) good support is grouping in the housing weld jig will to weld good positioning pipe and welding;
(5) positioning pipe and support are welded;
(6) Welding Testing.
Described step (2) welding position is angle welding, spot welding location in positioner, and welding parameter is: SMAW, direct current, electric current 90～130A, voltage 18～25V.
Described step (3) is for weld joint on inner side, the positioning pipe horizontal level symmetrical welding that interlocks, and rotate on the side weld limit, keeps welding to be in level, and welding parameter is DC current, electric current 140～170A, voltage 18～25V; For the lateral angle weld seam, during welding, housing is upright, flange level, staggered symmetrical welding, little electric current bottoming, welding parameter is: SMAW, DC current, electric current 90～130A, voltage 18～25V, large electric current capping, SMAW, DC current, electric current 140～170A, voltage 18～25V.
Described step (5) welding position is angle welding, and flip cover during welding guarantees horizontal welding, and welding parameter is: SMAW, and direct current, electric current 140～170A, voltage 18～25V,
Described step (6) is that after welding is completed, all weld seams are done the kerosene leak test, and then does the experiment of weighing of 2000Kg, then detection has or not distortion.
Advantage of the present invention is to have adopted welding procedure provided by the present invention to guarantee that effectively welding deformation in controllable scope, finally guarantees assembly quality.
