Fixed Welding Manipulator

The mechanical structure of the fixed welding manipulator is similar to that of the fixed column and boom. The boom is lifted and lowered by the lifting motor installed on the top of the column. The reducer drives the boom to adjust its position up and down through the chain and counterweight. The horizontal movement of the boom is controlled by frequency conversion speed regulation. It is realized by the gear rack driven by the motor and reducer installed on the base.



The most important thing is that the base, Column, and cross ARM of rotary welding manipulator are assembled and welded by robust steel plates, which all have stress relief treatment. The design has high strength, beautiful appearance,  but high robust strength above the standard.

Different from the fixed column and boom,  The column of the rotary welding manipulator can rotate in + -180 degrees manually or electrically.

What is the mechanism?

1. The column is installed on the base with slewing bearing. The electric rotation of the column is mainly driven by the motor reducer installed on the flange at the bottom of the column,  and the slewing bearing on the mobile trolley is driven by the output pinion, to drive the column to rotate.

2. Once the column is electrically rotated in place,  lock the column through the manual screw locking device on the flange at the bottom of the column to prevent the column from rotating and affecting workflow.

Why do you need rotary welding manipulators?

Due to limited factory space or not being convenient to lay tracks,  The mechanism can cover the barrel processing within a 360-degree orientation Workpieces can be processed at the same time without moving. Rotary welding manipulator saves time and labor and improves efficiency.

Can equip welding manipulator with other functions?

Consisting of the mechanical design of automatic rotation, i.e. up and down, left and right, and rotation function. Per industrial request,  We added extra functions into welding manipulators to become a complete set of processing machines. It is optional to equip with the robotic arm, welding gun (SAW, TIG, MIG, Plasma, etc),  Abrasive function, etc. Fengwei can offer you, welding manipulator, only or completed set per your request."

Application Field

  • Petrochemical Industry

  • Environmental Protection

  • Steel Structure

  • Power Tower

  • petrochemical industry

    The petrochemical industry plays a crucial role in enhancing the growth and economy of the world. Additionally, petroleum products produced in offshore and onshore exploration, refining, and oil production have also increased, resulting in increasingly complex waste production. This industry is a vital source of inorganic toxic and organic materials. 

    For the run of the industries present worldwide the top-quality equipment is mandatory. Several types of machinery producing industries are present worldwide but choosing the right one is a little confusing. Don't worry; we are here for your help. Giving the right solutions and shipments to your industry is our duty.

    Here are 3 must haves of welding automations for the fabrication process in the petrochemical industry:

    1) Conventional welding rotators

    2) fit up welding rotators

    3) welding manipulator.


  • Wind towers have saved 30% of nonrenewable energy while producing electricity. Today, there are hundreds of wind farms and sea areas are having thousands of wind towers. They hold the generator or dynamo blades, which are tones of weight. These wind power infrastructures are standing strong due to the use of welding rotators, welding manipulator, and welding positioners to be a tank assembly line. Experts in technology and engineering make them.

  • Steel structure has become an indispensable material type used in modern construction industry. Due to the feature of environmental friendly, it has been widely used in construction, such as steel structure factory building, ordinary steel construction building, boiler, pressure vessel, shipbuilding, electric power, petrochemical, petroleum engineering machinery, bridge construction, metallurgical machinery industry, wind power and power tower etc. The bird's Nest building in Beijing, China, is a classic masterpiece of steel structure architecture.

    The h-beam steel production line made by Fengwei Machinery is a highly automated steel structure production line which composes of CNC flame cutting machine, h beam assembly machine, h beam welding machine, and h beam straightening machine. It greatly reduces labor intensity and production costs, improves production efficiency.


  • The application of automatic welding and cutting equipment in the manufacturing process of steel tube tower can thoroughly optimize and upgrade the original production process. The traditional production mode adopts the operation of lifting semi-finished products, which requires a special person to be responsible for the lifting and operation of semi-finished products. It has high requirements on the environment and working space, which not only requires a lot of manpower and material input, but also has high labor intensity with low production efficiency. Different from the traditional production mode, the automatic cutting equipment integrates online monitoring, automatic upload and offload raw materials and other automatic functions, can reduce the workload of workers and work intensity, thus greatly improving the production efficiency. The production lines of cutting, pairing and welding can cover each area of the workshop, which can be operated as a whole or independently in each area.
