Key Features:
Precision Wire Oscillation: Enables wider beads, excellent sidewall fusion, uniform penetration, and smooth bead contour – essential for high-quality, defect-free welds (X-ray quality).
Optimized for Thick Plate: Ideal for welding shell sections exceeding 25mm (1") thickness in a single pass or fewer passes.
Superior Process Control: Digital control over all parameters (travel speed, oscillation width/freq/dwell, voltage, wire feed) ensures repeatability.
Reduced Welding Time: Wider beads reduce the number of passes required for thick sections.
Improved Weld Properties: Better heat distribution and fusion profile enhance mechanical properties and reduce distortion.
Enhanced Operator Interface: Intuitive touchscreen and remote control simplify operation and monitoring from a safe distance.
Data Logging: Records weld parameters for quality assurance and traceability.
Robust Magnetic Adhesion: Ensures reliable operation on vertical surfaces, even with vibration.
Application Scenarios:
Fabrication of high-integrity storage tanks for LNG, LPG, cryogenic services, or highly toxic chemicals requiring stringent weld quality standards (e.g., ASME Sect VIII Div 1/2, API 620 Appendix Q/R).
Welding of thick-walled pressure vessels and reactors in the oil & gas and petrochemical industries.
Construction of nuclear containment vessels or penstocks demanding ultra-high weld integrity.
Critical infrastructure tanks where weld reliability is paramount (e.g., strategic fuel reserves).
Applications requiring minimal post-weld grinding due to superior bead appearance.
