Welding Manipulator


1.The stand column and cross arm are made annealing treatment after welding. Therefore this welding manipulator has high intensity, little deformation, reasonable structure and long service life.
2.Cross-section of boom and column is calculated scientifically. Drooping of boom along horizontal travel is 2mm/m
3.The structure of this welding manipulator can be divided into stationary, stationary with rotation and moving with rotation.
4.The boom lifting device adopts anti-falling system. With ratchet structure, it makes this welding equipment more safe and reliable.
5.Elevation retraction adopts VFD, which will be stable and reliable during welding
6.Equipped with motor-driven cross-shaped micro-adjusting mechanism, it is convenient for the welding gun to adjust in a small range when this welding manipulator is welding.
7.Control roller has eccentric shaft, which can be decrease clearance between roller and rail
8.This welding equipment has motor-driven and manual drive column revolve.
9.The heavy and super heavy duty welding manipulators are equipped with platform, which is convenient for operators to observe and weld at closest position.


The welding manipulator is used in the pressure vessel, freezing equipment, construction of power station, metallurgical, engineering machinery, marine building, cladding of rolled rollers and petro-chemical industries.


The welding center consists of welding manipulator, automatic arc-submerging welder (or CO2, TIG welding machine, narrow-gap SAW, strip surfacing machine), the welding turning-roll and welding positioner. This welding equipment can weld metal vessels and metal welding structure by various welding methods.
The welding center can realize the integrated control. Also there are the welding tracking and monitoring system, arc oscillating unit, the arc length control, flux auto-feeding and recovering system for option. This welding manipulator has four types, including light duty (LHQ), medium duty (LHZ), heavy duty (LHW) and super duty (HCJ).
