YIHAI LASER Comprehensive FAQ: Frequently Asked Questions
I.Company Overview & Brand Advantage
1.1What is YIHAI LASER’s core business?
YIHAI LASER is a world-leading industrial laser equipment manufacturer specializing in the R&D, manufacturing, and sales of high-performance Fiber Laser Cutting Machines, Laser Welding Machines, and Laser Cleaning Machines. We are dedicated to providing efficient and reliable solutions for global manufacturing.
1.2What is YIHAI LASER’s competitive advantage in the global market?
Our advantage lies in superior cost-performance, the use of internationally recognized core components (e.g., IPG/Raycus laser sources), heavy-duty, high-precision machine construction, and comprehensive 7*24H multilingual technical support covering all time zones.
1.3Which international quality certifications do YIHAI LASER products hold?
All our equipment strictly adheres to international standards, holding certifications including European Union CE certification and compliance with the ISO 9001 Quality Management System, ensuring product safety and quality for global export.
II. Technology & Product Performance
2.1What are the standard cutting tolerances for YIHAI LASER fiber cutters?
Our high-precision cutting machines typically achieve positioning accuracy of ±0.03 mm to ±0.05 mm. Actual part tolerances (based on ISO 9013 standards) are typically controlled within the range of ±0.1 mm to ±0.2 mm, depending on the material thickness.
2.2What is the maximum thickness of aluminum that a handheld laser welder can join?
A standard 1.5 kW to 2 kW YiHai Laser handheld welding machine can reliably perform full penetration butt welding on aluminum materials with a thickness of 3 mm to 4 mm. By utilizing the automatic wire feeder and oscillation function, it can even efficiently process joints with a thickness of up to 6 mm.
2.3How can I improve continuity and speed when welding long seams with a handheld unit?
We recommend that you take advantage of the welding head’s lightweight, ergonomic design to optimize your welding technique and maximize the oscillating welding function (which provides a maximum weld pool width of 5 mm). This compensates for slight hand movements, improves stability, and reduces the need for pauses and posture adjustments.
2.4How do laser cleaners ensure they do not damage the base material?
We employ pulsed laser technology, using extremely short, high-peak-power pulses for selective ablation. By precisely adjusting the pulse width and frequency, the energy is absorbed only by the contaminant (e.g., rust, paint), allowing for safe and effective cleaning without causing thermal damage to the underlying substrate.
III. Purchasing & Customization Services
3.1Can I conduct material sample testing before purchasing?
Yes, we encourage you to use our Free Material Sample Testing Service. Please send your material to us, and we will provide detailed video demonstrations and a process report of the cutting, welding, or cleaning results to ensure the machine meets your exact requirements.
3.2Does YIHAI LASER support OEM/ODM or customized machine specifications?
Absolutely. YIHAI LASER is a highly competitive manufacturer supporting flexible OEM (Original Equipment Manufacturer) and ODM (Original Design Manufacturer) services, allowing us to tailor machine configurations, software, and exterior design to precise client requirements.
3.3What is the typical lead time for ordering a machine?
Lead times for standard, popular models (like handheld welders or mid-power cutters) are typically within 10–15 working days. Larger or highly customized systems usually require 20–30 working days for manufacturing, rigorous testing, and quality control.
IV. After-Sales Service & Technical Support
4.1What is the standard warranty commitment?
We offer a competitive quality guarantee of 2 to 3 years on the main parts of our machines (excluding standard consumables). The warranty duration for the laser source and key components may vary by model and brand, as specified in the contract.
4.2How does YIHAI LASER provide technical support to global clients?
We provide 7 days a week, 24 hours a day (7*24H) multilingual online technical support. Our engineers use remote diagnostic tools (like TeamViewer), video calls, and instant messaging to ensure rapid response and swift resolution of software or parameter issues in any time zone.
4.3If the fiber optic cable is accidentally bent, can I still use it?
No, you must stop using the machine immediately! Severe bending violates the minimum bending radius, which causes laser energy leakage, power instability, and can lead to internal overheating, creating a serious safety hazard and potentially burning the fiber. Contact us immediately for professional inspection or replacement.
4.4Where can I find operation manuals, software updates, and troubleshooting guides?
All documentation, the latest drivers, and video tutorials are available free of charge in the “Download Center” or “Service Support” section of our website.
V. Safety and Maintenance
5.1What are the most important occupational health and safety measures when using laser equipment?
The most important measure is the mandatory use of DIN-certified laser safety glasses rated for the specific wavelength. Additionally, a professional fume extraction and filtration system must be used to safely handle toxic smoke and micro-particulates generated during cutting or welding.
5.2How can I tell if the welding head’s protective lens is contaminated or internally damaged?
If the lens surface shows irregular burn marks or spots, it is usually due to spatter or dust contamination. If the burn mark is concentrated at the center of the lens, it likely indicates an internal optical alignment issue or thermal hotspot. Stop the machine immediately and contact us.
5.3What daily maintenance should I perform to ensure stable, long-term machine operation?
Daily maintenance includes: checking and cleaning the protective lens, ensuring the chiller water temperature, pressure, and fluid level are correct, and periodically replacing the coolant (using deionized or distilled water) to prevent the buildup of scale.
