2022 Best Handheld Fiber Laser Welding Machine in USA

Handheld fiber laser welding machine uses a pulsed laser with a wavelength of 1064nm generated by the laser to radiate the surface of the workpiece after beam expansion, reflection, and focus. The surface heat is diffused to the inside through heat conduction, and the width, energy, and peak power of the laser pulse are precisely controlled through digitalization. With parameters such as repetition frequency, the workpiece is melted to form a specific molten pool, so as to realize the laser welding of the workpiece, and complete the precision welding that cannot be achieved by the traditional TIG welder & MIG welder.

Handheld Fiber Laser Welding Machine

The advantages of fiber laser welding system are energy concentration, no pollution, small solder joints, wide range of weldable materials, high applicability, high efficiency and high speed welding. Products with high requirements for welding seams are welded by laser welding equipment, which not only has small weld seams, but also does not require solder. Laser welding system can be manually programmed for welding, and the path is automated.

Handheld Fiber Laser Welder

The hand-held fiber laser welding system can weld difficult-to-access parts, and implement non-contact remote welding, which has great sensitivity. It can stop welding at room temperature or under special conditions, and the fiber laser beam welding system is easy to install. When the laser passes through the electromagnetic field, the beam will not shift. The laser can be welded in vacuum, air and certain gas environments, and it can stop welding when it passes through glass or materials that are transparent to the beam.

Handheld Laser Welding Machines

The hand-held fiber laser welding machine is composed of laser system, laser power supply system, console and fiber transmission system, industrial television observation system (optional), special cooling system and other parts.

Optical Fiber Transmission System

Transmission fiber: optional according to welding spot requirements;

Minimum focus spot diameter: 0.3mm;

Working distance of objective lens: 70mm;

Focus adjustment range: 20mm.

Operation Console (Optional)

The work surface is made of stainless steel. The space of the work surface can include a bracket for the display and measuring instruments; the volume is small and the layout of the work surface can be determined according to the needs of users, such as installing a manual lifting mechanism.

Side-Axis black and white CCD observation system.

Three-channel black and white CCD camera, side-axis placement, 14" high-resolution black and white monitor.

Laser Dedicated Cooling System

Patented design, dual-circulation cooling, precision temperature control system. The coil structure is made of all-titanium alloy. The evaporator, water tank, pump body are all made of high-strength non-metallic materials or stainless steel to ensure water quality. The imported low-noise jet self-priming centrifugal pump makes the pure water circulate and cool the laser. The refrigeration compressor performs a secondary cycle cooling on the circulating water.

The hand-held laser welding machine will generate heat when it is working, so it is necessary to configure a laser chiller for cooling and heat dissipation. The stability of the laser chiller affects the normal operation of the laser welding machine. At present, the mainstream chiller brand for cooling handheld laser welding machines on the market is S&A. The S&A brand CW series laser chiller, with innovative refrigeration technology and stable quality advantages, has gradually developed into a standard product of mass modular production, which is deeply loved by manufacturers of laser industry production equipment.

Laser Power System

The pulsed laser power supply of handheld laser welder is a special power supply system dedicated to supply power to the pulsed xenon lamp. It is generally composed of charging circuit, energy storage unit, discharging circuit, trigger/pre-ignition circuit, logic control circuit and electrical operation circuit.

The function of the charging circuit is to provide charging power for the large-capacity capacitors in the energy storage unit. According to the characteristics of energy storage capacitors, constant current charging is the best charging method. This power supply uses a constant current charging circuit called LC constant current source. This circuit has simple structure, convenient control, high reliability and constant Advantages such as good flow characteristics.

Handheld Laser Welding Projects

Laser welding machines are generally used for tailor welding and repair welding of metal materials. The working principle of laser welding is to use high-energy laser pulses to heat a small area of the material. High-temperature energy diffuses from the surface of the material to the inside, and forms a specific molten pool after melting. The material in the whole process is high temperature, so how should we use handheld laser welder safely?

Handheld Laser Welding Safety Tips

Handheld fiber laser welders are generally used for tailor welding and repair welding of metal materials. The whole process of laser welding is that the materials are in a high temperature state, so how should we use the handheld laser welder safely?

1. During the operation, if there is an emergency, such as water leakage or abnormal laser sound, you need to immediately press the emergency stop button and quickly cut off the power supply.

2. The external circulating water switch of laser welding must be turned on before operation. Because the laser system adopts water cooling method, the laser power supply adopts air cooling method. If the cooling system fails, it is strictly forbidden to start working.

3. It is strictly forbidden to touch all circuit components in the machine while working. When the laser welding machine is working, the circuit is in a high voltage and high current state. Untrained personnel are prohibited from operating the machine.

4. It is strictly forbidden to directly use the eye scanning laser when the laser is working to avoid eye injury. It is forbidden to use external equipment to reflect laser light during laser work.

5. Do not disassemble any parts of the machine at will, and do not weld when the safety door of the machine is opened, and do not aim the laser head at the equipment parts.

6. Do not place flammable and explosive materials where the laser light path or laser beam can be irradiated to avoid fire and explosion.
