Further, the plane area of the multi-size fixing clamp is 55-65% of the plane area of the fixing base.

Further, the plane area of the multi-size fixing clamp is 60-65% of the plane area of the fixing base.

Compared with the prior art, the utility model has the advantages of it is following:

(1) the to-be-welded part has supporting force for abutting the flange and the multi-size fixing clamp in the vertical direction, and also has stress generated by arranging the multi-size fixing clamp outside the to-be-welded part in the horizontal direction, so that the whole clamping is very stable;

(2) the utility model discloses a so convenient to detach's bolted connection mode, if treat welded corrugated metal pipe's pipe diameter size to change to some extent, can only change the many sizes fixation clamp of the light of the inside, just can drop into the production of another size batch fast, and is very convenient.

Drawings

FIG. 1 is an assembly view of a welding jig according to an embodiment;

FIG. 2 is a view showing the welding jig in the embodiment;

the reference numbers in the figures indicate: the welding device comprises a fixing base 1, a groove 11, a first bolt hole 12, a multi-size fixing clamp 2, a second bolt hole 21, a piece to be welded 3, an end cover 9 and a flange 91.

Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
