Robotic arc welding
Robotic MIG/MAG and TIG welding with even beads and less rework.
Ideal for: Structures, frames, brackets and steel or stainless parts in series.
- Controlled parameters and paths
- Greater repeatability across production runs
- Integration with the cell and its peripherals
What it includes
What a cell comes with
6-axis robot
With the torch cable routed through the arm so it does not snag.
MIG/MAG or TIG source
With wire feeder and parameters per program.
Positioner
Rotates the part to always weld in the best position.
Seam tracking
Sensors or vision that correct the path when the joint varies.
What it is for
What gets automated
Robotic arc welding is defined by the joints, thicknesses, and positions: what gets welded, with which process, and in which sequence. Robot, welding source, fixtures, safety, and operator access are considered within a single proposal, with parameters and paths validated per part.
- MIG/MAG welding of assemblies and structures
- TIG welding for applications that require it
- Stations with positioners and multiple robots
Clear expectations
What it can and cannot do
It can
- Keep speed, angle and distance constant along the whole bead.
- Weld with two stations: one is loaded while the other is welded.
- Correct the path if the part arrives with small differences.
It cannot (without help)
- Fix poor fit-up or out-of-size cuts.
- Choose the parameters on its own: they are set and tested on real parts.
- Reach hidden joints if the part design does not allow it.

FAQ
Frequently asked questions
Which arc welding processes can be automated?
MIG/MAG and TIG, among others. The choice depends on the material, thicknesses, and joint requirements; it is defined during application analysis.
How is weld quality ensured?
Through defined parameters, validated paths, and agreed acceptance criteria. Testing is performed on real parts before commissioning.
Can a part that needs to rotate be welded?
Yes: with positioners and tilt tables the part is oriented for welding in position. Robot-positioner coordination is part of the cell design.
What is the difference between robotic arc welding and spot welding?
They are different processes: spot welding (resistance) joins overlapping sheets with a gun, while arc welding melts with filler material and is used for continuous joints. Each process has its own criteria and its own page.
Does it work if every part is different or fit-up is not exact?
Yes, with a system that searches the joint with a laser scanner and corrects with arc tracking: it generates the path from the 3D model and tolerates up to about 30 mm of fit-up error and 8° of deviation. It is the robotic structural steel welding solution.
