Product Abstract:

Fiber Laser Cutting Machine, absorbed advanced technology from Europe & USA, is high end NC machine domestically. Product, certificated by ISO9000 Quality Management System, is presenting stable cutting performance with 90% imported brand components from overseas, such as laser source, cutting head, NC controller & auto-nesting software etc. Cutting machine is structured with gantry frame, which has excellent strength and stability, and high precision ball screw with linear slider driven. Machine has been well calibrated to achieve fast cutting speed without compromising high precision, for sheet metal cutting less than 4mm applications. Furthermore, fiber laser, which is a new technology with best beam quality, perfect focused beam spot size, high plug efficiency, maintenance free, cost effective and compact size, no lasing gas required, is deemed to be a revolutionary manufacturing tool of machinery.


Product Description

The W series of pulse Nd:YAG laser welding systems are suitable for a wide range of precision spot & seal welding and cutting applications in the electronics, medical, automotive and fine mechanics markets. Typical applications include:

- Welding of stainless steel, aluminium alloy and other metals

- Welding of electron guns, titanium capacitors

- Spot welding of optical fiber coupler parts

- Welding of containers

- Seal welding of lithium batteries

 

Laser welding has a number of advantages over conventional techniques including:

- low heat input

- reduced distortion 

- no mechanical forces

- no tool wear and hence

- consistent weld penetration

 

W series laser welding systems use optical beam delivery. An assistant gas nozzle is also provided. CNC control system provides a convenient programming on the welding/cutting speed, pattern, laser beam on/off, gas on/off. The laser power is adjustable by setting laser pulse width, pulse repetition rate and lamp operation current.

 

A laser welding system typically consists of laser head, switching power supply, CNC control system, beam delivery, motor-driven XY stage & chiller.

Mould Laser Spot Welding Machine

 

The multi-purpose laser welding system (also called as laser mould welder, mould repair) is specially designed for the mould industry and used in repairing of precision moulds, such as mould manufacture for digital products, mobile phone, toy, automobile and motorcycle, and moulding industry. Through the repairing of moulds, it is possible to reuse the moulds, save the production cost and improve the working efficiency significantly. This technology can also be used to modify the design or size of moulds to reduce the development period.

 

 

Features

The working principle of this laser deposition welding system is to use laser high thermal energy and the melting technology in spot to process the welding and repairing of minute parts. It makes up the shortage of traditional hydrogen arc welding in repairing precision surfaces, avoids the two difficulties of thermal strain and after-treatment, and saves the production period of mould.

 

Advantages

It is specially designed for the mould industry and the technology is imported from Germany. With unique structure design, it is suitable for repairing of large, medium and small moulds.

1. Ceramic converging cavity is imported from the Britain. It is corrosion resistant and high temperature resistant, and has 8-10 years service life. The life of xenon lamp is more than 8 million times.

2. Use the most advanced light shielding system to eliminate the irritation to eyes by light during working.

3. The laser head and optics part can be rotated for 360°, upward/downward lifting and forward/backward pushing, suitable for repairing of large, medium and small mould.

4. The parameters are controlled by intelligent remote controller, which is simple and convenient.

5. The work bench can be lifted, and moved in three dimensions, the size of light spot can be adjusted.

 

Suitable Materials

The materials that can be welded are extensive: cold work alloy steel, hot work alloy steel, nickel tool steel, high grade steel, steel alloy, high tenacity aluminum alloy, etc.

Galvanometer Scan Laser  Welding Machine

 

This laser welder uses galvanometer scanning method, features high welding speed, high precision and good light beam mode, and is suitable for precision laser spot welding of various parts. During single spot welding, the working efficiency is 4-10 times higher than common laser spot welding because the idle stroke positioning time is significantly reduced. The scanning laser welder consists of YAG solid laser, laser power supply, optical scanning system, 3D adjustable work bench, industrial PC system, cooling system, laser indication system and operating cabinet.

This welder provides dedicated laser welding software based on Windows platform. The welding spots or graphs can be imported and edited in the dedicated software, or edited in other software such as AutoCAD and CorelDraw and then processed in the dedicated software. This welder features stable quality, convenient operation and easy maintenance.

 

Application:

This welder is mainly used in highly efficient laser spot welding or seal welding of mobile phone shielding case, mobile phone metal shell, capacitor metal shell, metal shielding grid in computer, shaver blade, electronic connector and other electronic products.
