Welding processes — Robotic welding cells FAQ
Process-specific questions about robotic welding: MIG/MAG, TIG, spot, laser, brazing, cladding. What robots can automate and what limits each process.
What welding processes can robots actually perform?
Quick answer: Industrial robots can automate virtually any welding process: MIG/MAG (most common, ~70% of robotic welding), TIG, spot welding (dominant in automotive), FCAW, laser welding, plasma, brazing and cladding. The real question is not whether a process is automatable — it's whether your part is ready for automation.
| Process | Best for | Robotic difficulty |
|---|---|---|
| MIG/MAG (GMAW) | Steel, stainless, aluminum 1-12mm, serial production | Easy — most mature |
| TIG (GTAW) | High-quality finish, thin material, sanitary, aerospace | Medium — slower, precise prep needed |
| Spot (RSW) | Automotive body-in-white, sheet metal | Easy — dominant since 1980s |
| FCAW | Heavy structural, high deposition, outdoor-grade | Easy — requires extraction |
| Laser | EV batteries, automotive lightweighting, thin precision | Hard — tight gap tolerance, high capex |
| Plasma | Stainless thin sections, precision | Medium — specialty |
| Brazing / MIG brazing | Zinc-coated automotive, low distortion | Medium |
| Cladding / Overlay | Wear protection, oil & gas, refurb | Medium — process expertise critical |
The bottleneck is rarely the welding process itself — it's joint accessibility, part repeatability, fixture rigidity and weld preparation. A good integrator will tell you that almost any welding process can be automated, but not every welded part is ready for automation.
Modern research on robotic welding confirms this: the 2024 arXiv survey on active visual sensing methods shows the field is now focused on seam tracking, defect detection and 3D weld pool measurement — meaning the question has shifted from “can the robot weld?” to “can the robot find and follow the real joint?”.
