3) SAW welding flux system: Hopper/ recycling unit, and conveying tubes, in case of SAW (Submerged arc welding) being adopted in Welding Column and Boom;
4) Control console of welding power supply, and welding seam tracker, that conform to welding modes being adopted in specific Column and Boom Welding Manipulator;
1) For SAW (Submerged arc welding), please check product section of “LHZ models High Efficiency Welding Column and Boom with SAW”;
2) For CO2 GMAW, please check product section of “LHZ series Precise and Efficient Welding Column and Boom with GMAW”;
3) For Strip Cladding, please check product section of “LHZ series Accurate and Fast Column and Boom Welding Manipulator with Strip Cladding”.
1) It collects on real time position data of welding torch;
1) Importance: The welding seam tracing unit is a very powerful tool for guaranteeing on superior welding quality of LHZ series automatic high precision Welding Column and Boom;
2) On the other hand, guaranteeing on superior performance of the entire set of Welding Equipment, depends on coordination of all the working units of the Column and Boom Welding Manipulator.
1) What is Blind Welding: When the Pipe Tank Welding Machine is used for producing longitudinal and or circumferential welding seams on internal wall of cylindrical workpieces, which operator can not see directly on welding point, such operation belongs to blind welding;
1) Loading capacity at the front end of horizontal boom;
