Flat laser cutting retrofitting
SERVICE HOTLINE
Details
The planar laser‑cutting‑to‑welding robotic workstation is an integrated, intelligent machining system designed to address the pain points of conventional steel‑structure plate processing—such as fragmented workflows, mismatched precision, low efficiency, and heavy manual intervention. By combining high‑precision planar laser cutting with automated robotic welding, the workstation enables seamless, end‑to‑end production of steel‑structure plates, including material preparation, hole punching, edge trimming, groove profiling, and automated welding. It comprehensively resolves the industry’s longstanding challenges—poor cutting accuracy, extensive secondary grinding, frequent weld rework, and cumbersome process handoffs—and is widely applicable to both mass‑production and custom‑fabrication scenarios involving steel‑structure panels, equipment bases, enclosure structures, bracket connection plates, and non‑standard flat components.
The workstation leverages a mature planar laser cutting system to perform pre‑cutting operations, employing high‑power fiber laser technology to achieve high‑precision cutting, contour profiling, hole punching, chamfering, and the one‑step formation of weld grooves on carbon steel, low‑alloy steel, and other types of structural steel plates. Compared with conventional flame and plasma cutting, planar laser cutting minimizes thermal distortion, produces clean, burr‑free cut edges, and delivers exceptional dimensional accuracy, effectively eliminating issues such as plate warping, rough cut surfaces, and angular deviations. This eliminates the need for extensive manual grinding and correction, providing highly precise, consistently uniform standard workpieces for subsequent welding processes. By reducing defects like misalignment, uneven gaps, and assembly deviations at the source, it lays a solid foundation for automated welding.
At the welding station, the equipment is equipped with a high-precision six-axis welding robot system, featuring intelligent weld‑seam recognition and adaptive tracking technology. Tailored to the standardized forming characteristics of laser‑cut workpieces, it can reliably execute a wide range of welding processes, including flat‑plate butt joints, corner joints, full‑penetration welds, and multi‑layer, multi‑pass welds. To meet the demands of retrofitting workstations for producing diverse plate types and specifications, the system incorporates a comprehensive library of steel‑structure welding procedures. It automatically selects optimal welding parameters based on plate thickness, material, and weld‑seam grade, while fully automating weld‑path planning and posture adjustment. The resulting welds exhibit uniform, well‑formed profiles and stable mechanical properties, effectively preventing common quality issues such as porosity, slag inclusions, incomplete penetration, and excessive distortion. With a high nondestructive‑testing pass rate, the system fully complies with steel‑structure engineering acceptance standards.
