Metal Welding

Metal welding is mainly divided into gas shielded welding, argon arc welding, and laser welding.

Laser Welding Industry Solution

Argon Arc Welding

Argon arc welding is suitable for welding carbon steel, alloy steel, stainless steel, refractory metals such as aluminum and aluminum-magnesium alloys, copper and copper alloys, titanium and titanium alloys, as well as ultra-thin plates with a thickness of 0.1mm. It can perform all-round welding, especially in the inaccessible parts of complex weldments.


  1. It can weld most metals and alloys except for aluminum and tin, which have a very low melting point.
  2. AC argon arc welding can be used for welding aluminum and aluminum-magnesium alloys, which have relatively active chemical properties and are prone to the formation of oxide films.
  3. No welding slag and spatter during welding.
  4. It can perform all-round welding. You can choose pulsed argon arc welding to reduce heat input. It is suitable for welding 0.1mm stainless steel with high arc temperature. It has the advantages of low heat input, fast speed, small heated area, and small welding deformation.
  5. The filler metal and the amount added are not affected by the welding current.

Gas Shielded Welding

Gas shielded welding usually refers to the welding method using carbon dioxide or argon shielding gas. It uses welding wire instead of welding rod. CO2 gas shielded welding has high efficiency, while argon gas shielded welding is mainly used for materials such as aluminum, titanium, stainless steel, etc.

If there is rust, oil and other debris at the arc ignition position of the workpiece, it may lead to ignition failure. This situation can be effectively prevented by repeating the arc ignition operations using the reignition function.



If a robot stops due to reasons such as arc-quenching, starting it again directly will result in incomplete welding. By using the arc quenching restart function, the robot can move back a specified distance at a specified speed after the arc is quenched, and then continue its operation under normal welding conditions.


When the "Scrape" is activated, the robot will move back and forth even if the arc ignition fails. If the arc ignition is successful during this movement, it will move back a certain distance and then continue with normal welding.

Gas pre-flow, arc-quenching

Execute the arc ignition instruction and begin wire feeding at a slow speed before the robot reaches the arc ignition position. When the robot reaches the arc ignition position, the wire contacts the workpiece to ignite the arc. This improves welding efficiency.

Anti-sticking treatment

Output the anti-sticking current and voltage before the end of welding to prevent the wire from sticking.

Automatic wire-stick release

When the arc is quenched, wire sticking sometimes occurs. In order to prevent this from happening, an instantaneous relatively high voltage is output at the end of welding to prevent the wire from sticking.

Laser Tracking

By utilizing laser sensors to obtain the accurate position of the weld seam, the robot can adjust its end effector position during the welding process, ensuring that the torch always moves along the seam. This ensures perfect formation of welds, reduces thermal load, increases productivity, keeps the torch in an ideal position, compensates for production, equipment and operational tolerances, and reduces programming work and achieves consistent, reproducible connections for complex weldments.

Multi-Layer Multi-Pass Welding

Multi-layer multi-pass welding is suitable for welding thick plates with wide and deep joints. It can reduce heat input, minimize deformation, and lower the probability of defects. It is applicable to various types of welds, such as butt, fillet, or plug welds.

Weaving Welding (Sine/Triangular/Circular)

During the welding process, the robot weaves regularly to control the weld width and improve the quality of interlayer and surface welding.

Intersecting Line

Our system supports intersecting line welding with or without positioners. Only the radius and position of the two cylinders that generate the intersecting lines need to be calibrated. For intersecting line welding with positioners, the positioner and robot work together to complete the intersecting line trajectory during the welding process. For intersecting line welding without positioners, the robot completes the trajectory alone.

Arc Pressure Tracking Welding

The arc voltage tracking system refers to using the arc voltage as the sensing signal to monitor the voltage during welding in real time. Through the automatic control of the arc height, it is not necessary to adjust the up and down height of the torch when the pipeline is automatically welded, which is automatically completed by the arc voltage tracking system.

After realizing this function, there is no need to worry about the phenomenon of arc breaking during welding due to the unevenness of the weld seam caused by the ovality of the pipe. The arc voltage tracking system will automatically adjust the height of the torch through the automatic control of the arc height.

Arc Tracking Welding

When welding thicker workpieces using arc tracking technology, the fluctuation of current and voltage can be measured and compensated by weaving welding, so as to ensure the quality of the weld seam and save laser cost.

Intelligent Non-Teaching Programming Welding

iNexBot supports drag welding. After identification, the operator can manually drag the robot to the desired position and press the corresponding IO signal to record the position, and finally start welding according to the recorded trajectory.

Compared to traditional manual teaching welding, drag welding has higher flexibility and does not require inserting instructions one by one. It only needs to trigger the IO signal. The welding speed and nonwelding speed can be customized. This function can only be used after completing the dynamics identification.
