QH-GZ Zero-tailing Laser Tube Cutting Machine Weldseam
Identification Side-mounted Lathe
Description
The QH-GZ Zero-tailing Laser Tube Cutting Machine, integrated with
Weldseam Identification Technology and a Side-mounted Lathe, is a
high-precision, low-waste tube processing solution tailored for
automotive components, hydraulic systems, and mechanical
engineering. Its defining features—weldseam identification and
zero-tailing—work in synergy with the side-mounted lathe to
redefine tube cutting efficiency and accuracy:
The weldseam identification system automatically detects and
locates weld seams on round (Φ15-500mm) and square
(15×15-500×500mm) tubes, ensuring cuts avoid seam areas (critical
for structural integrity) and align with optimal material sections.
Paired with this, the zero-tailing technology limits residual tube
length to ≤5mm per cut, drastically reducing material
waste—especially for high-value metals like stainless steel.
Supported by the side-mounted lathe, which stabilizes tubes of
5500-6500mm length during processing, the machine maintains ±0.03mm
X/Y-axis positioning and repositioning accuracy, delivering
consistent, burr-free cuts across tube types. Equipped with a
1500W-20KW laser power range, it handles diverse tube thicknesses
in one pass, while its 2T weight and 9620×2950×2080mm dimensions
balance industrial robustness with workshop space adaptability for
medium-scale production.
Quick Detail
- Dual Core Features: Weldseam Identification (auto-detects tube welds, avoids defective
cuts); Zero-tailing (≤5mm residual, minimal scrap); paired with
Side-mounted Lathe (stabilizes 5500-6500mm tubes).
- Key Specs: Cuts round (Φ15-500mm)/square (15×15-500×500mm) tubes; 1500W-20KW
laser power; ±0.03mm X/Y precision.
- Fit: Automotive/hydraulic industries; 2T weight + 9620×2950×2080mm size
suits medium workshops.

Advantage
- Weldseam Identification Guarantees Cut Quality & Structural Safety: The auto-weldseam detection system eliminates manual seam checking
(a time-consuming, error-prone step in traditional cutting),
accurately identifying welds on round/square tubes within 0.5
seconds. By avoiding cuts through welds— which cause uneven edges
or material brittleness—it reduces defective parts by 60%-70% and
ensures compliance with structural standards (e.g., hydraulic tube
pressure resistance), critical for safety-focused industries like
automotive.
- Zero-tailing + Weldseam Synergy Maximizes Material Utilization: The zero-tailing feature’s ≤5mm residual waste is only valuable if
cuts align with non-welded sections (otherwise, short residual
tubes with welds are still scrapped). The weldseam identification
system ensures every cut targets optimal material, making the ≤5mm
residual fully usable or minimal scrap. For a workshop processing
300 6500mm-long stainless steel round tubes (Φ300mm) monthly, this
saves ~380kg of high-value material annually—lowering raw material
costs by 12%-15% vs. machines without weldseam detection (which
often produce weld-contaminated scrap).
- Stabilized Processing Boosts Efficiency & Precision: The side-mounted lathe works with weldseam identification and
zero-tailing to streamline workflows: it stabilizes 5500-6500mm
long tubes, preventing vibration that could misalign weldseam
detection or zero-tailing cuts. This eliminates re-clamping or
re-calibrating (common for long tubes), cutting setup time per
batch by 30%-35%. Combined with ±0.03mm axis accuracy, the machine
maintains consistent cut quality (e.g., precise holes, smooth
slots) even for large-diameter tubes (Φ500mm), boosting daily
throughput by 40%-45% vs. unstable cutters.
- Broad Tube Compatibility with Uniform Performance: Weldseam identification and zero-tailing adapt seamlessly to both
round (Φ15-500mm) and square (15×15-500×500mm) tubes. Whether
processing small Φ15mm hydraulic tubes (with thin welds) or large
500×500mm structural square tubes (with thick seams), the detection
system accurately locates welds, and zero-tailing reduces
waste—eliminating the need for specialized machines for different
tube types. This versatility maximizes equipment utility and lowers
capital expenditure for multi-tube-type production lines.
