Frequently Asked Questions
Laser Welding Machines that you see listed in this category are mostly stationery units that are suitable for large volume automated processing of objects. Many systems come with an articulated robotic arm and/or a gantry system for parts loading and offloading. In contrast, Handheld Laser Welders are portable and the laser beam is delivered to a handgun with an optical fiber. Whereas in Laser Welding Machines the beam delivery is machine controlled.
Laser welding is cleaner than a conventional Arc or TIG welding process. Laser welding is typically more precise, easier to automate, and offers a much cleaner production process. Moreover, the joints created with a laser welding machine are a lot smoother and require no post-weld processing such as grinding.
Laser Welding is a highly controlled process and thanks to this can be applied to a variety of metals including stainless steel, aluminum and aluminum alloys, brass, copper, titanium as well as a several precious metals including gold, silver, and platinum. Moreover, laser welding machines are known for their capability of creating hybrid joints between two separate metals.
Laser Welding offers a highly controlled process allowing creating precise, strong and neat joints between objects. The high concentrated energy in a relatively small spatial domain minimizes thermal warping that plagues other alternative methods. As a result, you can create long seems of continuous welds without damaging the pieces. The other advantages include environmental friendless, absence of consumables and minimal maintenance of the equipment.
Laser welders listed on this category are sophisticated high end industrial grade equipment and their price varies significantly with the options offered including the loading / off-loading system, beam delivery method, laser power, laser source quality, etc. If you find a model of interest please contact the respective supplier for pricing information or for a personalized quote.
Laser welding machines are versatile tools that can operate in very demanding applications. One of their limitations is the thickness of the objects being joined. Because of the localized nature of heat delivery laser welding is usually limited in how thick of objects can be joined together. In contrast torch welding can heat larger areas. The other main disadvantage of laser welding machines is their high price tag which is usually much larger compared with alternatives. However for large volume projects requiring precision, laser welding machines can actually be more economical saving money on consumables, post-weld processing and reduction of production scrap.
Yes, the laser weld is narrow with an excellent depth-to-width ratio and high tensile strength. If the correct parameters of welding are chosen, the resulting joints are very strong and uniform.
There can be many factors affecting the weld quality including the machine parameters such as the laser power, the speed of welding, the focal spot size of the laser beam, preparation of the seams before welding, etc. While these machines are generally easy to operate, they do require some initial training to achieve high quality of welding.
Laser Welding Machines: Precision, Speed, and Versatility in Modern Manufacturing
Laser welding machines have revolutionized the manufacturing landscape, offering unparalleled precision, speed, and adaptability across various industries. By utilizing concentrated laser beams to fuse materials, these machines enable high-quality welds with minimal thermal distortion, making them indispensable tools in today's production environments.
Understanding Laser Welding Machines
At their core, laser welding machines employ focused laser beams to join materials, typically metals, by melting the interface between components. The process can be executed in continuous or pulsed modes, depending on the application's requirements. The high energy density of the laser allows for deep penetration and narrow weld seams, resulting in strong and precise joints.
