Principle: Laser welding is a welding process that uses laser action to produce instantaneous melting on the metal surface to connect the metal.　　Features: Due to the continuous development of miniaturization of components, small solder joints, high soldering strength, and small heat-affected zone a

The pulsed fiber laser with adjustable pulse width adopts MOPA to construct two-stage amplification, and the pulse width and frequency are independently adjustable, making more laser applications possible. The pulse width is flexibly adjustable from 60 to 350ns, the peak power is up to 10kW, and the repetition frequency is up to 1000kHz. It is equipped with an independent research and development on-line isolator, which is an ideal laser source for laser fine processing.

With the rapid development of the global manufacturing industry, the application of welding technology has become more and more extensive, and the level of welding technology has also become higher and higher. New welding technology methods are constantly emerging, and professional welding equipment is changing day by day. At the same time, domestic and foreign welding equipment manufacturers have also demonstrated their strengths in various ways, especially by exhibiting a wide range of products and advanced technologies at the exhibition. From the development of carbon arc welding at the end of the century to the present, it has only a history of more than one hundred years, and hundreds of methods have been formed, and the level of welding technology has reached a new height. Welded structures are developing in the direction of large-scale, complex and high-parameters.

Dual-beam welding of aluminum alloy is also a way to eliminate air holes. A 6 kW continuous fiber laser was used to perform dual-beam butt welding of 5052 aluminum alloy. The two-beam parallel and serial welding modes and welding at different welding speeds were studied. The study of seam morphology and structure found that there are large holes in the welds welded in parallel with dual beams, and welding aluminum alloys in series can obtain good weld formation without porosity.

1. Process characteristics of laser weldingAccording to the mechanism of weld pool formation, there are two basic modes of laser welding: thermal conductivity welding and deep penetration welding. The former uses a lower laser power density (105～106W/cm2). After the workpiece absorbs the laser, it o

Laser welding uses high-energy laser pulses to locally heat a material in a small area. The energy of laser radiation diffuses into the material through heat conduction, and the material is melted to form a specific molten pool. It is a new type of welding method, mainly for the welding of thin-wall

The parameters that directly affect the quality of laser welding include: laser pulse energy, laser beam spot diameter, laser pulse frequency, laser pulse width, laser pulse waveform, relative light absorption rate of the welded material, welding speed, protection Gas etc.　　The energy of the laser p

Laser welding technology is a comprehensive technology integrating laser technology, welding technology, automation technology, material technology, mechanical manufacturing technology and product design. It is ultimately embodied as a complete set of special equipment and a matching process. As an

Use an acetone solution ultrasonic cleaner for 25 minutes before welding to remove oil and other impurities on the surface of the sample. Continuous laser and pulsed laser are used to weld the samples respectively. After the welding is completed, the surface morphology of the weld is observed in a precision measuring microscope.
