The QH-GZ Zero-tailing Laser Tube Cutting Machine, integrated with Weldseam Identification and Beveling Cutting technologies, is a specialized solution for tube welding prefabrication—designed to streamline high-precision processing of round and square tubes in automotive components, hydraulic systems, and structural engineering. Its core innovation lies in the synergy of two key functions:
The weldseam identification system automatically scans and locates tube weldseams with ±0.1mm accuracy (compatible with both round tubes Φ15-500mm and square tubes 15×15-500×500mm), eliminating manual weldseam alignment errors. Paired with this, the beveling cutting module supports multi-type 坡口 profiles (V-type, U-type, Y-type) and adjustable angles (0°-45° in 0.1° increments), ensuring bevel cuts are precisely aligned with identified weldseams—critical for optimizing weld joint fit-up.
Complemented by its foundational strengths: it handles tube lengths 5500-6500mm, maintains ±0.03mm X/Y-axis positioning/repositioning accuracy for consistent bevel quality, and features zero-tailing technology (≤5mm residual tube length) to minimize material waste. Powered by a 1500W-20KW laser range, it adapts to diverse tube thicknesses, while its 2T weight and 9620×2950×2080mm dimensions balance industrial robustness with workshop space adaptability.

Advantage
Weldseam-Aligned Beveling Reduces Welding Defects: The auto weldseam identification system (±0.1mm accuracy) eliminates manual marking errors that often cause misalignment between bevels and weldseams. By ensuring bevel cuts are precisely matched to weldseam positions, it reduces weld gaps and uneven fusion—lowering welding defect rates (e.g., porosity, incomplete penetration) by 50%-60% compared to traditional machines requiring manual weldseam tracking.
Dual Efficiency: Time Savings from Identification to Beveling: Manual weldseam location and bevel setup for a 6500mm-long Φ300mm tube typically takes 20-30 minutes; the QH-GZ’s auto identification cuts this to 2-3 minutes, while one-pass beveling (powered by 1500W-20KW laser) completes the process in 10-12 minutes total. Combined with zero-tailing (no post-cut scrap trimming), it boosts batch processing efficiency by 40%-45%.
Consistent Bevel Quality Across Diverse Tubes: Whether processing small Φ15mm hydraulic round tubes or large 500×500mm structural square tubes, the weldseam identification system maintains ±0.1mm positioning accuracy, and the beveling module retains uniform angle precision (±0.5°). This consistency ensures weld joints meet strict industry standards (e.g., ISO 5817 for steel welding) across different tube sizes/types, avoiding rework from inconsistent bevel-weld alignment.
Cost Optimization: Material + Labor Savings: The zero-tailing feature (≤5mm residual) reduces material waste, while auto weldseam identification eliminates the need for skilled workers to manually locate weldseams. For a workshop processing 200 6500mm-long stainless steel tubes (Φ200mm) monthly, this translates to ~240kg annual material savings and ~150 labor hours saved—cutting overall operational costs by 12%-18%.
