（6）Positioner is removed after cooling to be welded.
Beneficial effects of the present invention：Compared with prior art, effect of the invention is as follows：
（1）The present invention utilizes distensible plate swelling shrink-ring, and shrink-ring struts rear swelling jaw cylinder both ends, can during welding
Reduce the deformation at jaw cylinder both ends, avoid secondary operation of the jaw cylinder because of deformation, once can property processing in place, substantially increase plus
Work efficiency rate and welding quality, process time is shorter, greatly reduces manufacturing cost, more time saving and energy saving, efficiently solves existing
Have in technology excessive needs long processing time, manufacturing cost caused by carrying out secondary operation high, time-consuming for being deformed after welding
The problem of laborious, the present invention also have simple in construction, applicable, maneuverable feature；
（2）Welded in the present invention by welding to position and coordinate point position formula to spend, constant temperature during welding can be ensured, further
Welding quality is improved, effectively prevent the generation of large deformation.
