10. a kind of welded gaps control method, which is characterized in that filled using welding as described in any one of claim 1 to 9
Set, the welded gaps control method the following steps are included:
The side that first driving assembly drives the slide unit to drive first clamp assemblies towards second clamp assemblies
To movement；
When the end face of the weld tabs is encountered in first weldment pushing on first clamp assemblies, the sensor is provided
Signal controls first driving assembly and continues to move down the distance of L1, and first clamp assemblies are due to by the weldering
The position-limiting action of the end face of piece remains stationary；
High-frequency induction heating, the weld tabs fusing are carried out, wherein the weld tabs is greater than the L1 with a thickness of L2, the L2；
Second driving assembly drives first clamp assemblies to move down the distance of L1, and the welded gaps are maintained at
L2-L1。
