9～12r/min (rpm).
It is preferred that described electric parameter includes that electric current and voltage, described electric current are 220～260 milliamperes, institute
Stating voltage is 26～32 volts.
In this programme, for the straight tube to be welded of different size, namely according to thickness and the pipe of straight tube to be welded
Footpath size, electric current when working by arranging the motor of welding gun and magnitude of voltage, it is possible to reach to control weld seam equal
Even purpose.
It is preferred that the width of described weld seam when being 13～15 millimeters described hunting period be 3～4 seconds.
It is preferred that described parts to be welded are flange.
It is preferred that described turning rolls is used for driving described straight tube uniform rotation to be welded.
It is preferred that described rocker is used for driving described welding gun at the uniform velocity to swing along described weld seam.
The most progressive effect of the present invention is: the straight tube welding system that the present invention provides, and passes through turning rolls
Uniform rotation and the at the uniform velocity swing of rocker so that the pipe fitting commissure to be welded welding time of staying uniformly and
Controlled, it is possible to avoid, owing to the welding time of staying controls burn-through phenomenon that is improper and that cause, making simultaneously
Obtain gas in molten bath to overflow in time, it is to avoid producing a large amount of pore, additionally speed of welding uniform, controllable makes heat
Amount is uniformly distributed in seam crossing, thus avoid the next parts follow-up to be welded of commissure extending stress band and takes off
The problem fallen.Further, two welding guns of PLC Synchronization Control are used to synchronize to carry out the two of straight tube to be welded
The individual welding treating welding end, can complete two welderings treating welding end of straight tube to be welded by rotating straight tube the most to be welded
Connect work, thus improve the efficiency of welding.The straight tube welding system that the present invention provides can improve straight tube weldering
Efficiency, minimizing pore, reduction burn-through probability and the raising even weld degree connect, it is ensured that the quality of welding.
