Do you know how to weld large pressure vessel

Due to the large demand of oil and natural gas, not all places have these materials, so in order to transport and storage convenient, people use pressure vessels to store and transport.So how pressure vessels are airtight depends on the welding machine.The large volume of the pressure vessel and the amnesty of storage products require that the welder can move up and down, and the length is long enough.Today we are going to introduce such a special welding pressure vessel welding machine.

Detailed introduction of welding manipulator

Welding manipulator/welding column and boom is a kind of widely-used and high-automated auxiliary equipment in welding industry.Through the rotation of column and retraction&lifting of boom,welding manipulator meets welding requirements of cylinders with different sizes.Welding head is fixed at one end of welding manipulator to carry out automatic welding.This kind of welding manipulator could also be operated together with welding rotator/tank turning roller to carry out round and longitudinal welding of inside and outside seam,which has got extensive application in Boiler,Petrochemical,Shipbuilding and Steel structure industries.

Product features of welding manipulator

1.     Structure:fixed type,fixed with rotation type and movable type

2.     Both column and boom are cold-blended and goes through annealing treatment

3.     There is anti-falling device to ensure the safety of boom lifting

4.     Boom retracting adopts VFD,being stable and reliable

5.     X-Y slide is fixed on one end of boom,which can be controlled by hand control panel

6.     Control roller bears eccentric shaft,which can decrease clearance between roller and rail

7.     Column revolve could be recognized by manual operation or electric drive

8.     Control unit includes:electric control board and hand control panel.Interface with positioner and rotator is offered

9.     Operation:Trolley,Director chair or platform,drag chain,seam tracking and monitor system,and flux recovery system.
