Second step：Pipe basetray is placed horizontally in rigidity fixed plate；
3rd step：By workpiece to be welded（Pipe）Pipe basetray is put into, and according to workpiece to be welded（Pipe）External diameter adjust
The height of adjustable rigidity fixed plate is saved, and adjusts the groove gap of workpiece to be welded, makes two workpiece grooves alignment to be welded（Manage
Son assembles error-free variable, zero clearance）；
4th step：Tightening clamp nut makes adjustable rigidity fixed plate be tightly pressed against above workpiece pipe to be welded, that is, treats welder
Part is locked on pipe basetray；
5th step：Pipe to be welded is fixed in spot welding；
6th step：Frock clamp is removed, automatic welding device is placed and starts formal welding.
Trial show that, the utility model is in Ship production field joint pipe argonaut welding operation process, the work
Clamps substantially improve workpiece to be welded（Pipe）Assembling precision, eliminate conventional hand assembled pipe（Fixed spot welding）Cause pipe
Sub- assembling precision is unstable（Gap and wrong variable, which exist, to be changed）And the weld defect triggered（Such as lack of penetration, burn-through and undercut
Deng）, fusion penetration stabilization, the weld seam that surface is smooth, reinforcement is concordant can be obtained.According to the different external diameter of pipe sizes, it can design multigroup
Similar frock clamp is used to aid in welding, and is not only readily available steady quality, shapes quality weld attractive in appearance, reduces and reprocess
Work, is greatly improved welding efficiency, and alleviates the labor intensity of welder, reduces production cost.In addition, the present apparatus makes light
