The joining force is established by pressing the component against a conformal clamping device or a special glass. While exhibiting a high level mechanical stability, the glass has to let the laser light through. Our engineers are able to design and build custom laser welding solutions to meet your production needs.
Our range of Fiber Lasers are “fit and forget” and are inherently zero maintenance with all of the traditional Laser components built into a fiber optic. This removes the requirement for re-alignment and makes it a truly industrial tool which can be operated with a minimum amount of fuss and hassle. DIVYA MEDIA PUBLICATIONS PVT. LTD is in the business of publishing magazines from last 20 years in the industry. Today it is recognized as one of the leading publishing company headquartered in the Mumbai, India.
Whether you require, high processing speed, complex weld geometries or multi-layer joints, our Wobble-3+ provides unique solutions for a diverse range of welding applications. After the laser beam is focused, a small spot can be obtained, which can be accurately positioned and used in the group welding of micro and small size workpieces for mass production. Hand-held fiber optic transmission laser welding machine has an 8-meter-long imported fiber optic connection laser head, thus welding a far off product or a large type of product that cannot be moved around easily. Due to the fiber transmission and the concentrated laser beam various metals can be welded with ease. It’s capable of spot welding, butt welding, stack welding, sealing welding, and complete complex plane straight lines, arc and any trajectory welding. High welding efficiency, close to none consumables, good welding effect and easy to operate.
Material compatibility is determined by a few factors including surface energy and polymer chain length, but the most important consideration is to find plastics with similar or overlapping melting temperatures. The latter helps us determine what products we show you on our site and elsewhere, and to measure the number of visitors to our websites. The combination will create a diversified photonics technology company with significantly increased scale and market reach. This design for a waterproof jacket has laser-welded seams, which are more effective as a water barrier than stitched and taped seams. They are robotized and automatically manage the positioning of the part under the laser source.

A lens in the nozzle’s laser entrance aperture provides a gastight sealing of the nozzle chamber and focuses the laser beam. In addition, the nozzle tip serves as a capacitive clearance sensor, ensuring a constant distance to the sheet surface of about 1 mm in cooperation with a closed-loop control of the machine axes. Metal fiber laser cutting machine improve the metal cutting efficiency.
As a complete system provider, TRUMPF also supplies process sensor systems. The continuous process monitoring increases quality and enables you to control your process accurately and reliably. The strength of the seams produced corresponds to that of the base material. To get a black part typically plastics are doped with carbon black, however, carbon black is also a great infrared absorber making it impossible to use in the upper layer during transmission welding.
The result is very short process times of only around 100 ms. Components that have a low level of complexity and are produced in high quantities are particularly suitable for this process. However, if the component geometry changes, the form of the beam also has to be adapted. Transmission laser welding can be applied to composite materials with glass or polymer fiber reinforcement, and matrices that do not have high filler content. When carbon fiber is used or the matrix is black or heavily filled, the direct laser welding method may be used, which does not require the beam to pass through the part. The process offers a new method of welding textiles that melts only the joint surfaces, not the outer surfaces of the material.
Welding is usually used to focus the laser, generally choose 63~254mm (2.5″~10″) focal length of the lens. The flow rate should also be controlled, otherwise the laminar flow of shielding gas becomes turbulent and the atmosphere becomes involved in the molten pool, eventually forming porosity. The protective gas is injected through the nozzle at a certain pressure to the surface of the workpiece. It is not easy to cause porosity because of the light mass and can escape.
The reason for this difference is firstly due to the different degrees of ionization of the gas molecules and also due to the difference in the diffusion of the metal vapor caused by the different densities of the protective gases. Ionization energy 24.4615.6814.55.967.617.83As can be seen from the table, the plasma cloud size varies with the protective gas used, with helium being the smallest, followed by nitrogen, and the largest when argon is used. The presence of plasma as second energy on the working surface makes the depth of melt shallower and the weld pool surface wider. The second role of using a shielding gas is to protect the focusing lens from metal vapor contamination and sputtering of liquid molten droplets. The use of surface coating or surface generation of oxide film method to improve the absorption of the material to the beam is very effective. The absorption of the laser by the material depends on some important properties of the material, such as absorption rate, reflectivity, thermal conductivity, melting temperature, evaporation temperature, etc.
