Rectilinear Seam Welding TRIZ Cases
- Calibration Roller Force Sensing for Stable Roll Seam Welding
Force sensing on calibration rollers tracks shell overlap width, helping stabilize roll seam welding and reduce tool wear.
- Sheet Metal Blank Rounding With Speed-Matched Roller Transfer
Servo-matched roller speed enables slip-free blank transfer during rounding, reducing edge damage, scrap, and weld defects in can body production.
- Dual-Anneal Seam Welding for Crack-Resistant High-Strength Steel
A two-pass seam weld with immediate and second annealing tempers brittle martensite in high-strength steel, reducing cracks and improving ductility.
- Roll Welding Calibration Feedback for Container Seam Overlap
Measured calibration force reveals seam overlap during roll welding, helping stabilize container body production and reduce tool wear.
- Resistance Welding With Spacer Interlayers for Non-Weldable Metals
A welded spacer interlayer enables resistance joining of non-weldable metals, avoiding cold cracks, embrittlement, and added forming cost.
- Barrel Tank Seam Welder Z-Bar Guide and Forging System
Segmented Z-bar guides compensate for sheet metal rebounding during translation, enabling precise edge alignment for high-strength steel seam welding.
- Door Sash Welding Segmentation for Distortion Control
Segmented seam and spot welding reduces distortion during bending while maintaining torsional rigidity.
- Electric Resistance Welded Steel Pipe Hardness Control
An electric resistance welded steel pipe with optimized chemical composition and microstructure.
- Pre-rounding Element with Actuation for Sheet Metal Rounding
A pre-rounding element uses an electrically controllable actuator to adjust pressurization on sheet metal blanks during operation.
- Electrode Roller Angle Control for Seam Welding
A seam welding system adjusts electrode roller orientation to maintain constant pressing direction.
- Dual Seam Welded Tubes Low Convergence Angle Forming
Interleaved upper and lower forming rollers maintain a convergence angle below 4 degrees to eliminate twisting and irregularities in dual seam welded tubes.
- Automated Reference Wheel Positioning for Mash Seam Welding
An automated measuring device positions a rotating roller to align the reference wheel vertically below a fixed point.
