Machine for Resistance Butt Seam Welding of Boiler Pipes and Other Items MSO-604
TU 16-683.001-83The machine is designed for welding of pipes and other items with circular cross-section (reinforcement bars, back ends of milling cutters, drill bits, broaching tools etc.) made of pearlitic, austenitic, low-and high-carbon alloyed steel with a section area up to 850 mm2 and an outer diameter up to 42 mm, using continuous flash and preheat cycle welding methods.
This machine can be used with shaped as well as aluminium and titanium alloy weldments with a cross-section area up to 300 mm2.
The machine has a through-type design, which allows the welding of both long and short weldments. It ensures high precision of offsetting and turning of the weldment axes.
The flash-off and heating drive is electromechanical. The clamping and upset drives are pneumatic.
The control system corrects the welding process in the event of abnormality.
