Best insight from top research papers

Laser welding of copper is a challenging process due to its high thermal conductivity and low absorptivity. Different approaches have been explored to overcome these challenges. One approach is to use high-power lasers in the near infrared wavelength range, which provide good results due to their excellent beam quality and established joining solution . Another approach is to use spatial beam oscillation during quasi-continuous wave (QCW) pulsed laser beam welding, which has shown improved weld quality and dimensions for copper-copper joining . In addition, in-process monitoring of weld penetration depth can be achieved using optical coherence tomography (OCT), which has been successful in stable welding processes . Furthermore, multiphysical simulations using comsol Multiphysics® software have been developed to predict and optimize welding parameters for good quality welds .

How can laser welding be used to heal wounds?5 answersLaser welding can be used to heal wounds by providing a non-invasive and efficient method for tissue closure. The process involves the use of laser radiation to create a strong adhesion between the wound edges, resulting in the formation of a laser weld. This weld is formed by the transformation of a biopolymer nanocomposite, which consists of carbon nanotubes in a biopolymer matrix, due to the absorption of laser radiation and its conversion into heat. The addition of single-walled carbon nanotubes to the solder composition increases the ultimate tensile strength of the laser welds by 80%. Laser tissue welding eliminates the need for sutures or staples, reducing scar formation and allowing for watertight closure. The use of laser tissue welding with biocompatible scaffolds made of electrospun fibers enhances the adhesion at the boundary with connective tissue, providing a strong seal. Laser welding with gold nanorod-collagen nanocomposites restores the strength and leak pressure of ruptured tissue, reducing the risk of postoperative complications.
The most effective ways to weld thin plate copper to thin plate aluminium using laser?4 answersLaser welding is an effective method for joining thin plate copper and thin plate aluminium. The challenge lies in the low laser absorption rates and high reflectance of these materials. To overcome this, high-density, high-quality lasers with infrared wavelengths and high beam quality can be used. Process parameters such as welding speed and laser output modes also play a role in achieving high-quality welds. It is important to avoid excessive heat input to prevent burning or lack of fusion. The use of a blue laser emitting at 450 nm has also shown promising results, with smooth and narrow beads achieved at high welding speeds. Simulation models can be employed to optimize the laser beam path and absorption, taking into consideration the materials' physical properties and the laser spot position. Overall, a combination of appropriate laser parameters, careful control of heat input, and optimization through simulation can lead to effective laser welding of thin plate copper to thin plate aluminium.
What parameters of laser welding can be used for copper joints?5 answersLaser welding parameters that can be used for copper joints include laser power, welding speed, oscillating amplitude, and oscillating frequency. Increasing laser power can help increase the maximum welding speed. Oscillating amplitude and frequency can be used to control the weld width and penetration depth. Additionally, the combination of power distributions with a core and ring beam can enable a wider and more stable keyhole in deep penetration welding, reducing spattering and melt ejections. It is also important to consider the wavelength of the laser, as different wavelengths can affect the vapor capillary geometry and keyhole depth. By optimizing these parameters, it is possible to achieve complete penetration, good weld formation, and high-quality copper joints.
Why lasers are used for metal ptocessing?5 answersLasers are used for metal processing because they offer high-precision machining with minimal thermal influence on the processed materials. This makes them suitable for working with advanced materials such as titanium alloys, nickel-based alloys, and steel. Laser technology has been progressively developed over the years and is commonly used for traditional processing applications like cutting, marking, and welding. Femtosecond lasers, in particular, have proven to be useful for microstructuring solid targets and achieving controllable ablation with small heat-affected zones in metallic materials. They allow for ultrafast energy deposition and rapid ablation, resulting in high-quality structures. Additionally, femtosecond lasers have been used for metal surface treatment, where they can create a micro-nano composite structure on the metal surface, leading to excellent surface hydrophobic performance.
