Robotic spot welding
Spot welds in the exact place and with the same pressure, part after part.
Ideal for: Sheet metal and stamped subassemblies, as in automotive parts and appliances.
- Repeatable welds and controlled parameters
- Sequences and access defined per part
- Integration with the subassembly line
What it includes
What a cell comes with
Medium or high payload robot
To move the gun, which is usually heavy, quickly and precisely.
Welding gun
Resistance gun with its current and pressure control.
Tooling and positioners
Hold the sheet and present it so the gun reaches every spot.
Guarded cell
Fencing and sensors so the operator loads safely.
What it is for
What gets automated
Robotic spot welding is defined by the parts, thicknesses, and access: what gets welded, with which gun, in which order, and with what parameter control. We assess the complete station —robot, gun, positioners, safety, and sequence— to integrate it with the existing line.
- Spot welding of sheet metal and assemblies
- Stations with one or several robots
- Integration with positioners and transfers
Clear expectations
What it can and cannot do
It can
- Always deliver the same number and location of spots.
- Handle heavy guns without fatigue.
- Coordinate with transfers and other robots on the line.
It cannot (without help)
- Join parts that are not seated correctly in the tooling.
- Replace electrode maintenance: it has to be scheduled.
- Make continuous joints: that is what arc welding is for.

FAQ
Frequently asked questions
What is a robotic spot welding cell?
A station where one or more robots position a resistance welding gun over the parts, with the sequence, parameters, and safety defined for the assembly.
How many robots does a spot welding station need?
It depends on the number of welds, access, and the required cycle. Multi-robot cells are coordinated to share welds and sustain the production rate.
Which welding gun is used with the robot?
The gun is selected by thickness, material, access, and cooling. Its integration with the robot, transformer, and control is part of the cell design.
Can an existing welding line be automated?
Yes, with a review of the line, transfers, and available signals. The scope —new station or in-line integration— is defined before quoting.
