Unlike our two other choices, the Neutec® PulsePoint™ Studio™ Plus 20 comes with a maximum pulse power of only 20 joules. This affects how much time it will take for the device to get the job done. Larger jewelry studios and experienced professionals who work on many pieces of jewelry a day might need a more powerful and faster model. The Neutec® PulsePoint™ Studio™ Plus 20 is also a great choice for people who’ve never worked with such a device before. It comes with a complete start-up kit that will get you working in no time.
A demonstration of a fiber laser being used for transmission plastic welding. This latest generation fiber laser facilitates integration into factory automation networks using Ethernet/IP protocol and embedded controller technology in order to save time and money by eliminating the need for PLC custom programming. In our Laser Welding Services, both the workpiece and the laser beam are manipulated by means of robotics. During the Laser Welding process, the laser beam can be adjusted to varying sizes and heat intensity, from .004 to .040 inches. It is unlikely that this combination of optics and Laser would be used in an industrial application, but this process shows the effect beam quality has on weld properties.
Delivering a focused heat source, laser welding creates a strong seam at a high speed. Some of the laser welding machines utilize a 5- or 6-axis control and others utilize a fully articulated wrist. Generally for low thickness of metal like 0.5 to 0.6 mm, it is difficult to weld with traditional technology but with fiber laser welding system it can be done efficiently, cleanly and smoothly. Also aluminium to aluminium welding was a typical task with traditional technology but with this technology; one can do aluminium welding very easily. Because of increase in consumption of fiber source and price war among fiber laser source producers, the price of fiber laser source is coming down. As a result, the prices of fiber laser cutting machine, welding machine, and marking machine are also coming down and they have become truly affordable to anyone.
For a specific application, you would perform a cost-per-part calculation; what follows is a more general cost determination. At first thought it might seem that a deep weld joint is always desirable, but that’s not the case. For thin parts where full penetration is easy to achieve, it may be preferable to have a wider weld joint.
Therefore, certain laser power and a certain thickness of a particular material have a suitable welding speed range, and in which the maximum depth of melt can be obtained at the corresponding speed value. Beam spot size is one of the most important variables in laser welding, as it determines the power density. In mass production tests, laser remote welding has reduced the time by 80% compared to conventional resistance welding. Laser fusion welding is a welding method that uses a laser as the heat source to melt the base material of two plate parts at the corner of each plate part to form a liquid metal, and after it cools, a reliable connection is formed.
The HAZ is the portion between the melted metal and unaffected base metal under it that undergoes adverse metallurgical changes, growing the grain structure and softening the metal. For TIG welding, the HAZ can be as deep as 0.15 inch, while the typical range for pulsed laser welding is 0.008 to 0.012 inch. The larger HAZ for TIG welding means a greater reduction in hardness of the metal in that zone. For TIG welding, the material in the HAZ is softened by 15 to 22 HRc points, compared to 2 to 4 points using pulsed laser welding.
The manufacture of precise punching, pressing and casting tools by additive or subtractive laser welding is the answer to the challenges of industry 4.0. In practice, much higher temperatures are achieved during laser beam welding. Nevertheless, this spectrum clearly shows how variable this joining process is. It supports time spectroscopy and energy splitting or a combination of these two spectroscopic modes . Multi-channel fiber output, up to 4 fiber at the same time, significant cost savings, improve welding efficiency and reduce equipment space.
The lower levels of heat required by fiber laser welding are not only environmentally friendly, but also mean there is very minimal damage caused to surrounding components/materials and all of this is delivered at a lower operating cost. Mehta CAD CAM has introduced a welding machine equipped with 1 KW and 1.5 KW fiber laser sources having a hand-held laser welding gun. This controlled workpiece heating and cooling is not necessary with pulsed laser-welding equipment due to the low heat input.
Industry increasingly relies on sensors in both factories and products. New sensor technologies mean new product capabilities with improved performance and efficiency. When excited molecules of the same material come into contact and concurrently move to lower excitation states, they revert to being solids and develop a bond at the molecular level.
The parameters are adjusted by the lever in the sealed cavity, which is simple and highly efficient. Fast, efficient, deep, little distortion, little heat-affect area quality welding, welding points free from pollution, saves energy. You are provided with the laser, focusing optics with sensor system, and laser machine all from a single source and perfectly adapted to your specific application.
This high concentrated laser beam is focused to the desired location for the welding of the multiple pieces together. CAM is used to control the motion of the laser and workpiece table during the welding process. It works on the principle that when electrons of an atom gets excited by absorbing some energy. And then after some time when it returns back to its ground state, it emits a photon of light. The concentration of this emitted photon increased by stimulated emission of radiation and we get a high energy concentrated laser beam. They can even weld materials with a high melting temperature and high heat conductivity with utmost precision.
