Butt welding machine
Product Introduction
Pneumatic flash butt welding machine series communication：UNS-P
UNS：Recruitment frequency flash butt welding machine
P：rated capacity
For example: the rated capacity of 80 kva through labor frequency flash butt welder is expressed as UNS - 80
Main Features：
>> UNS flash butt welding of the working principle is: the butt welding of the workpiece, through the control of gas and liquid, first drive slow oxidation of the workpiece surface of welds and rising inequality flash removed after welding workpiece end face hot plasticizing, to quickly add another upsetting force make the two ends weld penetration.
>> Microcomputer controller, realize the clamp, flash, upsetting, maintain, resting, the whole welding process control, high control precision.
>> Welding product high strength, good compactness, virtual welding, slag inclusion, strong and beautiful.
>> Widely used in carbon steel, alloy steel, non-ferrous metal tubes, rods, plates, profiles between the butt welding of butt welding or between heterogeneous metal.
