Welding rotator with walking

The welding rotator is widely used in boiler, pressure vessel, petroleum, chemical industry, machinery, and other manufacturing industries. welding rotator is used to assist automatically welding inner and outer longitudinal or circumferential seams of cylindrical vessels. Such welding automation is convenient for wildman to operate and improve workflow efficiency.



The welding rotator is customized welding automation, optional for various functions in order to meet the client's specific request. In the picture, this is a type of welding rotator consisting of a travel feature along rails. Similar to a Traditional welding rotator, a Welding rotator with walking is mainly composed of a driving roller, idle roller, electric control system, but differently added on walking mechanism. The walking mechanism is optional for motorized travel and manual travel.

Mechanism of Welding rotator with walking

Two sets of driving devices are installed on the driving roller. The driving device consists of the motor and reducer, which are used to drive the rollers on the driver to rotate. A traveling mechanism is installed at the bottom of the driving roller unit, and the traveling wheels are synchronously driven by an AC motor and reducer, which can make the welding rotator walk on the guide rail.

Importantly, the travel system of the driving roller is double wheel drive, we designed accordingly a manual wheel lock device in the mechanism. Once the welding rotator travels to the destination, the wheels can be locked manually to prevent the trolley from moving by itself.

How to choose a manual or Welding Rotator with Motorized Travel?

1) If tight budget, we recommend that if the loading capacity of the welding rotator is between 2ton and 100 tons, the manual walking mechanism is still applicable, as the workman is still able to push the rollers.

2) If loading capacity is over 100ton, which is too heavy to push, an electric travel mechanism is a necessity. Such setting of Welding rotator with walking brings lots of advantages, i.e. time-saving, labor-saving and safety.

3) All operation button and control is centralized on one monitor. One workman can complete a series of processing procedures solely, including welding seam, rotating cylinders, transfer vessels without using cranes, etc.

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.
