12. the drill bit according to claim 8 working method of automatic high-frequency welder, which is characterized in that above-mentioned
In step 4, after the completion of welding, secondary rotation on the high-frequency induction welder and the rotary table in welding post is automatically closed
The direct current generator of shaft opens lifter switch, increase the high-frequency induction welder, the induction coil and is substantially higher than to pressure component
Weldment, then opens the rotary switch of stepper motor, and stepper motor drives the rotary table by gear set transmission
Live spindle rotates an angle, and the weldment is gone to handling station, takes out weldment.
13. the drill bit according to claim 8 working method of automatic high-frequency welder, which is characterized in that upper
It is further comprising the steps of before stating step 1: to open the control switch of electric pushrod I, electric pushrod I works, thus described in driving
High-frequency induction welder is moved left and right to realize that the induction coil left-right position is adjusted.
