How Handheld Laser Welding Works

Laser light from the source is transmitted through an optical fiber to the handheld welding head, where it is focused onto the workpiece surface. The laser energy is absorbed and converted to heat, melting the material or filler wire. Shielding gas protects the molten pool, forming a high-quality weld that securely joins the two pieces.

The water chiller cools and maintains constant temperature for both the laser source and welding head to protect critical components.

FAQ

Is training included?

Yes. Every machine comes with free online video training (2–4 hours) covering setup, parameter tuning, basic operation, and daily maintenance. Overseas customers can request on-site engineer support.

Can I use it with 220V household power?

Fiber Laser Cleaner

Wed, 28 Oct 2026 00:00:00 +0000

Product Overview

The fiber laser cleaner is a non-contact, green cleaning equipment. It uses high-frequency laser pulses to impact the surface — the light beam rapidly moves, converting into acoustic waves that return from the lower layer, creating resonance with incident waves that breaks down contaminants. Simultaneously, the differential absorption of laser energy between the substrate and surface contaminants causes instant thermal expansion, generating sufficient acceleration to overcome the adsorption force and detach contaminants.

Simple to operate, highly efficient and safe, it is especially advantageous for objects that cannot be moved.

Core Advantages

Non-contact processing — no substrate damage, no secondary pollution
Eco-friendly and efficient — no consumables, no chemicals, no dust emissions
Safe and reliable — modular controls with shielding and safety interlocks
Simple operation — intuitive touch screen, preset cleaning parameters at one touch
High efficiency — spot diameter up to 200mm for large-area rapid cleaning
Wide power range — 1000W / 1500W / 2000W / 3000W / 6000W available

Technical Specifications

Parameter	Specification
Name	Fiber laser cleaner
Laser Power	1000W / 1500W / 2000W / 3000W / 6000W
Operating Mode	Continuous / Modulation (Pulse)
Laser Wavelength	1080nm
Focus Spot Diameter	0 – 200 mm
Fiber Length	10 m
Cooling System	Water cooling
Power Supply	AC 220V / AC 380V
Overall Weight	~ 300 kg

Working Principle

Laser cleaning operates through two combined effects:

Resonance Shattering Effect — high-frequency laser impacts the surface; the beam converts to acoustic waves returning from below, creating resonance with incident waves that shatter contaminants
Thermal Expansion Detachment Effect — substrate and contaminants differentially absorb laser energy, causing instant thermal expansion of contaminants which generates enough acceleration to overcome adsorption forces and detach

Application Industries

Nuclear power industry
Shipbuilding
Tire molds
Rail transit
Automotive parts
High-end machine tools
Industrial molds
Steel structure rust removal
Ancient building restoration
Precision electronics cleaning

Typical Cleaning Targets

Rust — oxidation layers and rust on various steel surfaces
Grease — hydraulic oil, lubricants, heavy oil residues
Paint — old paint layers, coatings, protective film removal
Scale — post-heat-treatment oxidation, post-weld scale
Adhesives — industrial dust, weld spatter, surface attachments

Laser Marking Machine

Wed, 28 Oct 2026 00:00:00 +0000

Product Overview

Laser marking machines use a laser beam to create permanent marks on various material surfaces. The marking effect is achieved through material evaporation exposing deeper layers, or by physical/chemical changes induced by laser energy to “engrave” patterns, text, barcodes and other graphics.

Zhijie laser marking machines cover fiber, ultraviolet and CO2 three main types, suitable for precision marking on metals and selected non-metallic materials.

UV-5W	5W	Same as above
UV-7W	7W	Same as above
UV-10W	10W	Same as above
UV-20W	20W	Same as above

UV lasers produce a “cold processing” effect with extremely small heat-affected zone, delivering fine marks ideal for high-precision and high-smoothness requirements.

CO2 Laser Marking Machines

PSA Nitrogen Generator

Thu, 05 Nov 2026 00:00:00 +0000

Product Overview

The PSA (Pressure Swing Adsorption) nitrogen generator uses clean compressed air as its feedstock. Carbon molecular sieves adsorb oxygen and carbon dioxide under high pressure and desorb them at low pressure, separating nitrogen on site for immediate use — no cylinder handling, no liquid nitrogen delivery, and no evaporation loss. It is widely used for laser welding shielding, laser cutting assist gas, metal heat treatment, and food preservation.

Key Advantages

Generate gas on site, on demand — Cut out bottled and liquid nitrogen suppliers entirely; produce gas the moment you start the unit
Adjustable purity — Nitrogen purity from 95% to 99.999% in multiple grades to match different welding/cutting processes
Stable, self-regulating purity — Intelligent closed-loop control keeps flow and purity steady for consistent shielding quality
Low running cost — Cost per cubic meter is only 30%–50% of bottled/liquid nitrogen, so units pay for themselves quickly
Safe and convenient — Low pressure, ambient temperature operation; no high-pressure cylinders or cryogenic liquid
Saves labor and floor space — No cylinder swapping, compact footprint that sits right next to your production line
Smart touch control — Chinese LCD touchscreen showing real-time purity, flow, pressure and fault alarms

Advantages in Laser Welding Applications

The quality of the shielding gas (nitrogen) directly affects weld formation and cutting edge finish. On-site generation gives laser systems these unique benefits:

1. Stable gas flow, more consistent welds

Immediate on-site production keeps pressure and flow steady, giving uniform shielding at the nozzle and low-oxidation, consistent weld color
Avoids weld defects and spatter caused by pressure swings during cylinder changes

2. Controllable purity for multiple materials

When welding stainless steel, galvanized steel or aluminum, adjust the purity grade to precisely match the shielding requirement of each material
For cutting carbon steel or stainless steel, select the right purity for each plate thickness for cleaner edges

3. Integrated with laser lines, zero downtime

Gas production matches consumption in real time with no gaps, ideal for long continuous welding/cutting runs
One nitrogen system can serve multiple welders via centralized supply for maximum utilization

4. Batch consistency and easy scaling

Fully automated quality monitoring ensures consistent gas quality across production batches
Expand your line without renegotiating suppliers — just add capacity modules

Cost Comparison vs Traditional Supply

Aspect	Bottled Nitrogen	Liquid Nitrogen	On-site Generation (this unit)
Supply mode	Ordering & swapping	Tanker delivery	Produced on site in real time
Logistics & handling	Frequent cylinder swaps	Delivery + evaporation loss	No delivery, no handling
Cost per m³	High	Medium-high	Low (about 30%–50%)
Supply risk	Downtime during swaps	Delivery delays	No interruption
Storage safety	High-pressure cylinder	Cryogenic burn/vapor risk	Low pressure, room temp — safest
Floor space	Cylinder storage area	Storage tank + vaporizer	Minimal, next to the line
Purity control	Fixed grade	Fixed grade	Multiple adjustable grades
Ongoing cost	Rental deposits	Tank leasing	Only specialty filter media

Payback reference: For continuous daily use at moderate consumption, on-site generation typically recovers the equipment investment within 6–12 months through gas cost savings, after which savings continue.

FAQ

Is on-site generation cheaper than buying liquid nitrogen?

Low consumption with short hours might favor purchasing, but laser welding/cutting usually means steady, long-term use. On-site generation costs only 30%–50% per cubic meter, and eliminates cylinder deposits, deliveries and waiting — winning on both total cost and production efficiency.

What installation conditions are required?

You need 380V three-phase power, a 0.6–1.0 MPa clean compressed air source (or we supply a matching compressor), and a 5–45℃ ventilated area. The unit is skid-mounted and plug-and-play on arrival.

Are purity and flow guaranteed to be stable?

Yes. The PLC closed-loop control with inline oxygen analysis monitors continuously, and auto alarms activate on out-of-range concentration or flow, so the output always meets the process requirement.

Will one unit cover multiple welders?

Yes. Size the generator by total gas demand to centralize supply across several laser welders/cutters, and add matching modules when scaling your line.

What is the warranty?

Main unit: 12 months from shipment
Core components (carbon molecular sieves, etc.): per manufacturer standard
Consumables (filter elements, seals): 3 months
