Description
Technical field
The utility model belongs to nuclear fuel element welding field, and in particular to a kind of grid spacer abnormal shape spot-wedling electrode.
Background technology
300MW nuclear fuel assembly grid spacers, coaming plate spot welding position share the left side, the right, forward direction according to guide vane position
Three kinds of solder joint types.Due to the inside bending of guide vane, the guide vane for avoiding the bending of screen work lattice cell is needed in pinpoint welding procedure, just must
It must change the direction of screen work at any time by according to the situation of solder joint, the left side, forward direction, the right needed to change at any time when hand-manipulated
Become position, can just be soldered to can be soldered to solder joint and damage guide vane.
Change grid spacer welding position at any time in the welding process, one side operator is time-consuming and laborious, is also difficult to ensure
Grid spacer and welding electrode all good fits, it is excessive to be easy to cause spatter, or even solder joint burn-through occurs, causes positioning lattice
Therefore frame is scrapped.
Utility model content
It is continuous utility model aims to solve being needed when domestic 300MW nuclear fuel assemblies grid spacer resistance spot welding
The problem of changing screen work direction reduces operation difficulty, improves stability of the welding quality.
The utility model is realized in this way：
A kind of grid spacer abnormal shape spot-wedling electrode, generally long strip shape are divided into the part of left, center, right three；Left part is
End, shape are rectangular prismatoid, and left end is upper bottom edge, and upper end is right-angle side, and lower end is bevel edge；Right-angle side and horizontal folder
Angle is 6.85 ° to 7.15 °, and the angle of bevel edge and right-angle side is 14 °；Middle part is segmental arc, generally serpentine body, and upper end is " V "
The angle of the right-angle side of recessed portion, " V " shape left side and end is more than or equal to 20 °, and end right edge and horizontal angle are big
In equal to 14.85 °；Right part is fixing end, generally cuboid, and setting is used in welding there are two mounting hole to electrode
It is fixed；Pass through setting " V " recessed portion so that the lucky position of guide vane of 300MW nuclear fuel assembly grid spacers in welding
It in recessed portion, avoids interfering with guide vane, when carrying out grid spacer spot welding again in this way, does not have to the side for changing grid spacer
To remaining the grid spacer solder joint of the i.e. solderable all positions of forward position, saved the spot welding time.
The roughness of electrode left part end right-angle side position as described above is 1.6, the roughness of electrode outside surface thereof
It is 0.8.
Electrode as described above is integrally made of chrome zirconium copper alloy.
The utility model has the beneficial effects that：
After making the interior electrode (or lower electrode) of grid spacer into shaped electrode, when welding, saves two left-hand, dextrad welderings
Change in location remains a kind of welding posture, it is easier to ensure that welding electrode and workpiece fit-state are good, are conducive to stablize
Quality of welding spot.In addition, also reducing welding operation difficulty, save the spot welding time, when every grid spacer is than original saving 1/4
Between.
Description of the drawings
Fig. 1 is a kind of structural schematic diagram of grid spacer abnormal shape spot-wedling electrode of the utility model；
Fig. 2 is a kind of front view of grid spacer abnormal shape spot-wedling electrode of the utility model.
Specific implementation mode
The utility model is described further with reference to the accompanying drawings and examples.
As depicted in figs. 1 and 2, a kind of grid spacer abnormal shape spot-wedling electrode, generally long strip shape, are divided into left, center, right
Three parts.Left part is end, and shape is rectangular prismatoid, and left end is upper bottom edge, and upper end is right-angle side, and lower end is bevel edge.Directly
The arm of angle and horizontal angle are 6.85 ° to 7.15 °, and the angle of bevel edge and right-angle side is 14 °.Middle part is segmental arc, generally
Serpentine body, upper end are " V " recessed portion, and the angle of the right-angle side of " V " shape left side and end is more than or equal to 20 °, end right edge
It is more than or equal to 14.85 ° with horizontal angle.Right part is fixing end, generally cuboid, and there are two mounting holes for setting, use
Electrode is fixed in welding.Pass through setting " V " recessed portion so that the 300MW nuclear fuel assembly positioning lattices in welding
The guide vane of frame is located exactly at recessed portion, avoids interfering with guide vane, in this way when carrying out grid spacer spot welding, without changing
The direction for becoming grid spacer, remains the grid spacer solder joint of the i.e. solderable all positions of forward position, when having saved spot welding
Between.
The roughness of electrode left part end right-angle side position is 1.6, and the roughness of electrode outside surface thereof is 0.8.
In the present embodiment, electrode is integrally made of chrome zirconium copper alloy.
The implementation of the utility model is explained in detail above in conjunction with embodiment, but the utility model and unlimited
In above-described embodiment, within the knowledge of a person skilled in the art, the utility model can also not departed from
Various changes can be made under the premise of objective.Existing skill may be used in the content not being described in detail in the utility model specification
Art.
