(3 votes, average: 5.00 out of 5)The Automated Oscillation Welding Carriage is engineered to replace slow and inconsistent manual welding on circular and curved structures. The Cruxweld DynaFlex 100S delivers precise, repeatable circumferential welding automation for storage tanks, pressure vessels, pipelines, and large cylindrical components.
This Automated Oscillation Welding Carriage combines a flexible magnetic track with a servo-controlled oscillation system, enabling smooth 360-degree travel on any radius. Designed for heavy industrial fabrication, it ensures consistent weld quality, reduced setup time, and higher productivity across all welding positions.
Runs on Any Shape or Diameter
The flexible magnetic rail adapts instantly to circular, curved, and straight surfaces, allowing the Automated Oscillation Welding Carriage to perform circumferential welding on tanks of varying diameters without custom fixtures.
Rapid Magnetic Setup
High-strength permanent magnets allow the track to snap securely onto ferrous surfaces without drilling or tack welding, significantly reducing setup time in tank welding automation projects.
Unlimited Welding Length
Interconnectable rail segments enable continuous travel for long circumferential or longitudinal seams on storage tanks, vessels, and pipelines.
Stable Vertical & Overhead Welding
The magnetic track maintains firm adhesion on vertical and overhead surfaces, ensuring slip-free motion and stable welding in all positions.
Reduced Labor & Faster ROI
By eliminating custom jigs and manual handling, the Automated Oscillation Welding Carriage lowers labor costs and delivers faster return on investment.
The Automated Oscillation Welding Carriage is equipped with a servo-controlled linear oscillation unit featuring five precision weaving modes. These oscillation patterns replicate the skill of an expert welder while maintaining consistent heat input and penetration.
Straight Travel Mode: Ideal for stringer beads, narrow joints, and precision cutting applications.
Square Wave Oscillation: Provides stable heat distribution for flat, uniform weld beads.
Triangle Weave Pattern: Optimized for root passes and controlled penetration on open joints.
Multi-Step Weave Mode: Designed for deep penetration and multi-pass welding on thick plates and pressure vessels.
High-Speed Wave Pattern: Produces smooth cap passes on wide joints with minimal post-weld grinding.
The Automated Oscillation Welding Carriage is designed as a universal welding carriage, compatible with MIG/MAG, FCAW, and TIG welding processes. Its adjustable torch holder supports standard welding torches, allowing easy integration with existing power sources.
By swapping the welding torch for a plasma or oxy-fuel torch, the system also functions as a welding and cutting automation carriage, enabling automated beveling, edge preparation, and cutting operations.
