welding robot automatic pipe internal welding machine for automatic pipeline welding
Internal welding clamp similar with internal alignment clamp, but it have additional function of full automatic welding system, when machine working, air source though motor and a serial valves to boost two rows clamp shoes against two pipe ends, though remote controller operate alignment and doing preheating advanced, make sure the welding ends temperature arrive to target standard, Fire, then welding action start, first clockwise root weld welding seam for half of pipe automatically, then anticlockwise root weld the next half of pipe, after completing welding, test whether welding seam arrive to target standard.
Technical points and advantages of DP internal welding clamp
Driven mode is double sides double wheels, each wheel is 90°to the horizontal plane
Travel parts are controlled by pneumatic type and electric type, exactly control method depends on actual situation.
Wire feeding part will be feed-back timely, automatic correction speedy function additionally.
-50°~+70°Fit for extremely cold and hot temperature work during -50°to +70°
Operation parts are controlled by near-by and remote controller, self-prepared control
High vibration frequency, small swing width
Swing width can be adjustable by triangular wave, trapezoidal wave and square wave, etc
Controller can correct Trim
Welding torch adjustable angle is ±15°
