Movable Assistive Arc Welding Robot
In the modern manufacturing industry, welding technology plays a crucial role. Arc welding, in particular, is widely utilized for joining metal components. To meet the increasing demands for high-quality and efficient welding processes, the movable assistive arc welding robot has emerged as a remarkable innovation.
I. Overview and Structural Design
The movable assistive arc welding robot typically consists of several key components. It has a robotic arm, which is the core part responsible for performing the actual welding operations. The arm is usually designed with multiple joints, enabling it to move with a high degree of flexibility in different directions. These joints are often equipped with high-precision servo motors, allowing for accurate control of the arm's position and orientation.
Attached to the end of the robotic arm is the welding torch. The torch is carefully engineered to deliver the welding current and shielding gas precisely. It can be adjusted in terms of angle, height, and distance from the workpiece to ensure optimal welding conditions.
The robot is mounted on a movable base. This base can be designed in various forms, such as a wheeled platform for easy movement on flat surfaces or a tracked system for better mobility and stability, especially in more complex working environments. Some advanced models even incorporate self-navigation and obstacle avoidance technologies, enabling the robot to autonomously travel to different workstations.
II. Operational Principle
When it comes to operation, the robot first needs to be programmed. This can be done through offline programming software, where technicians input the welding parameters, such as welding speed, current intensity, and electrode feed rate. They also define the trajectory of the robotic arm based on the geometry of the workpiece to be welded.
Once programmed, the robot starts its operation. The movable base transports the robot to the vicinity of the workpiece. Then, the robotic arm begins to move according to the pre-programmed path. As it moves, the welding torch ignites the arc, and the molten pool is formed on the workpiece. The shielding gas is continuously supplied to protect the molten pool from atmospheric contamination, ensuring the quality of the weld seam.
During the welding process, sensors play a vital role. For example, vision sensors can monitor the position and shape of the weld seam in real-time. If any deviation is detected, the control system can immediately adjust the movement of the robotic arm to correct it. Force sensors can also be installed to measure the contact force between the welding torch and the workpiece, preventing excessive force that could damage the torch or result in poor welding quality.
III. Advantages
High Precision and Quality: The precise control of the robotic arm and welding parameters guarantees highly consistent and accurate welds. Unlike manual welding, where human errors and fatigue can lead to variations in quality, the robot can maintain the same high standard throughout the production process.
Increased Productivity: It can work continuously without breaks, significantly speeding up the welding process. Moreover, the quick repositioning ability of the movable base allows it to switch between different workpieces rapidly, reducing downtime.
Improved Workplace Safety: By automating the welding process, workers are exposed to less hazardous fumes, intense heat, and potential arc flash hazards. This creates a safer working environment, reducing the risk of occupational injuries.
Flexibility and Adaptability: With the ability to be reprogrammed easily, the robot can handle a wide variety of welding tasks. Whether it's different workpiece geometries or welding materials, it can adjust its operation accordingly.
IV. Applications
Automotive Industry: In car manufacturing, numerous parts need to be welded together, such as chassis components, body frames, and exhaust systems. The movable assistive arc welding robot can precisely weld these parts, ensuring the structural integrity and safety of the vehicles.
Shipbuilding: For constructing large ships, welding is involved in joining thick steel plates. The robot's high-power welding capabilities and mobility make it suitable for handling the extensive and complex welding requirements in shipyards.
Aerospace Engineering: In this field, where the quality and precision of welds are of utmost importance, the robot can meet the strict standards. It can weld components like engine parts and fuselage structures, contributing to the reliability of aerospace vehicles.

Precautions for use
(1) The equipment number plate should be riveted at the specified position on the upper cover of the casing, otherwise the internal components will be damaged.
(2) The connection between the welding cable and the welding machine output socket must be tight and reliable. Otherwise, the socket will burn out and cause instability during welding.
(3) Avoid contact between the welding cable and metal objects on the ground to prevent short circuit of the welding machine output.
(4) Avoid damage and disconnection of the welding cable and control cable.
(5) Avoid deformation of the welding machine by impact and do not pile heavy objects on the welding machine.
(6) Ensure smooth ventilation.
(7) When used outdoors, the welding machine should be covered in rainy and snowy weather, but ventilation should not be hindered.
(8) The maximum cooling water temperature should not exceed 30ºC, and the minimum should not be frozen. The cooling water must be clean and free of impurities, otherwise it will block the cooling water circuit and burn the welding gun.
2. Regular inspection and maintenance of the welding machine
(1) Professional maintenance personnel should use compressed air to remove dust from the welding power supply once every 3 to 6 months, and pay attention to check whether there are loose fasteners in the machine.
(2) Check the cable for damage, the adjustment knob for looseness, and the components on the panel for damage.
(3) The conductive nozzle and wire feed wheel should be replaced in time, and the wire feed hose should be cleaned frequently.
3. Welding machine faults and troubleshooting
Before repairing the welding machine, the following checks should be performed:
(1) Whether the status and welding specification display on the front panel of the welding machine are correct, and whether the buttons and knobs are working properly.
(2) Whether the line voltage of the three-phase power supply is within the range of 340V~420V; whether there is a phase loss.
(3) Whether the connection of the welding machine power input cable is correct and reliable.
(4) Whether the grounding wire connection of the welding machine is correct and reliable.
(5) Whether the welding cable connection is correct and the contact is good.
(6) Whether the gas circuit is good, and whether the gas regulator or proportioner is normal.
