Weld Methods
Common robot weld methods include gas metal arc (MIG), gas tungsten arc (TIG), and plasma arc. Each method fits different metals and thicknesses. Material heat conductivity and melting point affect settings.
Path Planning
Software creates weld paths from 3D part models. Simulating the path before production avoids crashes and bad angles. Good paths cut cycle time and improve bead quality.
Adaptive Control
Arc sensors and laser trackers watch the seam during welding. The robot adjusts current, travel speed, and torch angle on the fly to fill gaps and keep the bead uniform.
Parameter Tuning
Use design-of-experiments to find the best current, voltage, and speed mix. Test small windows of settings and measure the results. Record the winning recipe for each part.
Quality Checks
Add vision or sensor checks inside the program. When a defect is spotted, the system can alarm or auto-correct. Save all weld data for traceability.
