Thermoplastics are polymer materials made from long-chain molecules that, above a certain temperature, can be reshaped or welded. Unlike thermoset polymers, which cannot be melted, the molecular chains in thermoplastics are not cross-linked and do not have a rigid network. At high temperature, the molecules are free to move and the material flows as a liquid. Industrial plastics have melting or softening temperatures in the 120–343°C range. While each of these lasers has its pros and cons, all are modern and reliable manufacturing tools. Monitor the waveform of laser pulsesWe recommend that you change the waveform according to the metal you intend to weld.
With additive manufacturing, components are generated layer by layer using powder and laser light on the basis of a 3D model. Any explicit consent from you to process your personal data can be revoked at any time by unchecking the following checkbox. Please note that up until revocation, the legal validity of consent-based processing remains unaffected. Wobble welding oscillates the beam back-and-forth at various frequencies to produces wider seams, more aesthetic welds and for parts with poor fit-up. LightWELD comes with optimized, preprogrammed wobble parameters and allows on-the-fly control of up to 5 mm of wobble welding at adjustable frequencies up to 300 Hz. For stainless steel, galvanized steel, mild steel and aluminum, you can weld single-sided up to 4 mm and up to 10 mm double sided – copper single-sided up to 1 mm and double-sided up to 2 mm.
It should be noted that the upper layer can be colored and even opaque using special non-absorbing colorants. Application of the system can fully or partially replace arc welding, resistance welding and other traditional welding processes. The industrial blue laser manufacturer has appointed technology industry veteran Guy Gilliland, Ph.D., as CEO alongside photonics executive Chris Baldwin as CFO. Semicrystalline types are a mixture of small crystallites surrounded by amorphous material.

Optical transmission fiber is optional on demand 5/10/20 meters, up to the range of free-to-adjust. Handheld Fiber Laser Welders with Wobble welding heads incorporate scanning mirror technology inside a standard weld head. By oscillating the beam with internal mirrors, the focal spot is no longer static, and can be dynamically adjusted by changing the shape, amplitude, and frequency. Portability remains the major challenge for laser welding technology, particularly in remote construction or repair jobs.

When it is something as valuable as your health, eyes, and let’s face it, our bottom line in business, you should buy a quality product that can be trusted to work properly, and made by people you can talk to and trust. Welding capacity expands from small parts to large heavy-duty objects, advantageous in welding workpieces of different sizes.
Jewelry Laser welder is corrosion resistant and high temperature resistant, and has 8-10 years’ service life. The part to the right is a gear sensor housing, a very common application in the automotive industry. Once the light energy is converted to thermal energy at the surface of the lower part, some of that energy must make its way into the upper layer in order for melting to occur in both parts. Good contact between the parts ensures that energy can be transferred via conduction.
Compared with argon tungsten arc welding or melting argon arc welding, laser welding has narrow weld seams, small heat-affected zones, reduced overlap joints, precise controllable welding process, and automation. Compared with traditional welding, laser welding has the advantages of small heat input and thermal influence, large aspect ratio, and automatic welding process. The shield gas, sometimes referred to as ‘cover gas’, has its roles in the laser welding process. The laser welding process often uses inert gas to protect the molten pool. Laser welding is usually done without filler metals so parts need to have good fit with a gap that’s less than 15% of the thickness of the thinnest component, which limits its scope of use.

Laser plastic welding, also often referred to as through-transmission welding, is a process of bonding plastic using focused laser radiation. Our spot welders are perfect for anyone needing a precise tool with maximum versatility in welding metals. The ergonomic design helps the operator remain comfortable as they create or repair metal parts. CLC’s laser welding technology rooted from the project in 2015 for transcatheter heart valve welding for Edwards Lifesciences. The different applications possible with each laser type are very dependent on the wavelength of light produced, which dictates the form of energy absorption in the plastic. But if you include the costs for capital equipment, floor space, overhead, and labor—that data to the right—things get more interesting.
However, an increase in pulse width decreases the peak power, so increasing the pulse width is generally used for heat conduction welding methods, forming a wide and shallow weld seam size, especially for lap welding of thin and thick plates. In the process of a laser pulse signal, the reflectivity of the metal changes with time. Therefore, high power density is very beneficial for material removal processes such as punching, cutting and engraving.
However, plastics processors will find that the alternative, pulsed laser welding, delivers a superior result with less damage to the base material, so the mold will produce better quality parts and last significantly longer after the repair. The laser light will continue on through the shutter assembly to the angled mirror and down through the focusing lens to the workpiece. The laser light beam used in our Laser Welding Service is coherent and has a high energy content, and when focused on a surface, laser light creates the heat used for welding. The other major advantage is, with the same fiber laser welding system one can weld any metal to any dissimilar metal.
