Seam Tracking
Seam Tracking Solutions for Automated Welding: Laser, Tactile & Robotic Options
Bancroft Engineering offers advanced seam tracking systems designed to enhance precision, consistency, and efficiency in automated welding. With solutions for nearly any seam geometry, our technologies are built to meet the needs of modern manufacturing.
Key Seam Tracking Options:
-
Laser-Vision Seam Tracking: Â 2D/3D profile sensors, advanced tack avoidance, and seam-finding technology with customizable cross slides.
-
Tactile Seam Tracking:Â Proven probe-based method with 50+ years of field use, swappable tips, and automatic seam scanning programs.
-
Robotic Through-Arc Seam Tracking:Â Cost-effective robotic solution requiring no extra sensors, suitable for certain weld geometries and processes.
Together, these systems integrate seamlessly into Bancroft’s automated welding machines, ensuring higher weld quality and reduced operator adjustments.

Laser-Vision Seam Tracking
- 2D/3D Profile Sensor
- 8×8 Standard Cross Slides – Custom Sizing Available
- Seam Trackers Integrated into Machine Control
- Advanced tack avoidance technology
- Advanced seam finding technology
- Able to sense nearly any seam geometry

Tactile Seam Tracking
- Seam tracking probes mounted on carriages
- Tried and true method – 50+ years of proof in field
- Incorporated tack avoidance – tuning necessary
- Swappable tips for different part geometries
- Automatic seam scanning programs
- 8×8 Standard Cross Slides – Custom Sizing Available

Robotic Through-Arc Seam Tracking
- Available for certain robotic welding applications
- Requires small weave in weld
- No additional sensors or slides required
- Joint geometry and process choice highly limited
- Less precise than laser-vision seam tracking

“Manual” Seam Tracking
- Operator manually controls joysticks to follow seams
- Best paired with welding cameras or submerged arc welding
- Simplest, lowest cost seam tracking option
- Many cross slide dimensions from 4×4 to 24×24 – custom available
