The welding positioner is mainly used to assist welding. The workpiece to be welded is passed through the rotating platform of the welding positioner to achieve the best welding position. There are many types of welding positioners. Among them, the most common ones are cantilever welding positioners, seat welding positioners, and two-seat welding positioners, and their forms are more L-shaped, U-shaped, and so on.

Components of welding positioner

Fengwei welding equipment has deep experience in the production and research and development of welding positioners. After more than 20 years of accumulation, Fengwei welding positioners have been upgraded many times for all fields of demand. It can be perfectly suitable for racks, The turning, displacement, and welding of non-long workpieces such as machine bases, flanges, and heads can also be used for assembly, cutting, inspection, etc. There are many welding positioners under Fengwei Machinery. The most common ones are Elevating welding positioner, Head And Tail Stock Welding Positioner, L-shaped welding positioner, U-shaped welding positioner, hydraulic welding positioner, and special welding. Displacement and so on.

Elevating welding positioner

Elevating welding positioner

Elevating welding positioner can adjust the position of the entire welding table by manual or electric two methods. And the application range of this welding displacement is extremely wide, it can be applied to the welding of almost all workpieces, and the tiltable angle can reach 135 degrees, and it can also achieve higher. The height of the worktable can be adjusted by manually adjusting the pin position, hydraulic lifting, or electric screw height adjusting to adapt to different types of workpieces.

(1) The load works smoothly and reliably and can be braked at any position.

(2) Anti-interference electric control system, remote control technology of hand control box.

L-type welding positioner

L-shaped welding positioner

The L-shaped welding positioner is also one of the popular products in the welding positioner series. It is mainly composed of a base, a column, a motor box, an L-shaped support arm, and a rotary table, and the structure of the L-shaped welding positioner is also very simple:

l The column is fixed on the base

l The motor box is installed on the top of the column

l The L-shaped support arm is installed on the upper part of the fixed plate at the front of the motor box

l The turntable is installed on the top of the front end of the L-shaped support arm.

The L-type welding positioner has many advantages. Compared with the traditional welding positioner, it has very high flexibility and the overall design structure is relatively simple. After many user feedbacks, Fengwei has received feedback from many small partners: Fengwei's equipment has a high degree of freedom and reliable carrying capacity; once the factory is purchased, it only needs to simply install the workpiece and pass it The pre-set program operation can complete the welding operation of the entire workpiece, which greatly improves the production efficiency.

U type welding positioner

U type welding positioner

The structure of the U-shaped welding positioner is relatively simple, mainly including a base, two uprights, an overturning pillar, a rotating material table, and an electric shock box.

l A first column and a second column are respectively provided on both sides of the base, and a turning support column is provided between the two columns

l Both sides of the flip support column are rotatably connected with the first and second columns through the first drive structure

l A rotating material table is set on the top of the flip support column

l The rotating material table is connected with the turning support column through the second drive mechanism.

By placing the material on the rotating material table of the U-shaped welding positioner, and by turning the support column and the rotating table, the adjustment of the material in two directions can be realized, and the structure is simple and the assembly is convenient.


There are many styles of welding positioner designed by Fengwei Machinery, almost from a single model to the entire production line, from a single industry to a multi-industry refinement, to meet the needs of various industries.

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.
