Laser Beam Welding is a fusion welding process in which two metal pieces are joined together by the use of laser. The laser beams are focused to the cavity between the two metal pieces to be joined. The laser beams have enough energy and when it strikes the metal pieces produce heat that melts the material from the two metal pieces and fills the cavity.
Our top choice for most people is the Neutec® PulsePoint™ Studio™ Plus 150 Laser Welder. This option offers a great price-quality ratio and has an incredible power capacity that’s able to handle a heavy workload. Plus, it’s compact and designed to fit all studios regardless of their size, which makes it a great choice for most people. The Neutec® PulsePoint™ Studio™ Plus 20 Laser Welder is our top budget-friendly pick, as it offers solid quality and comes with a refreshing amount of additional features for a great price.
From a practical standpoint, the use of beam delivery fiber expands integration options and facilitates the use of the laser in the manufacturing environment. Also, the high reliability, excellent uptime and favorable cost of ownership characteristics. In a fiber laser, the laser light is generated in an active fiber and guided to the work piece by means of a flexible delivery fiber, which acts as a “light guide”. In pulsed mode, the gain medium is pumped in bursts to generate short laser pulses. Power, duration and frequency of the laser pulses are important parameters for material processing.
When first starting to work with the laser welders, operators should experiment with five or six different alloys commonly used. It is also recommended to source different types of alloys in casting and strip/stamping form. This gives the operator a better understanding of the composition and thermal conductivity of the metals.
5) The beam intensity and fine positioning can be effectively controlled, and the operation can be easily automated. 3) High weld strength, toughness and overall performance due to purification and high cooling rate. Because of the incandescent heat source and the full absorption of non-metallic components, the impurity content is reduced, the size of the inclusions and their distribution in the melt pool are changed. The figure below shows the effect of the focal point position on the depth of melt and seam width of 1018 steel. Changes in the position of the focal point relative to the workpiece surface directly affect the weld width and depth. Focused spot size is proportional to the focal length, the shorter the focal length, the smaller the spot.
Therefore, if you need more memory cell capacity, you should invest in a higher-end laser welder that offers this feature. However, for the vast majority of even professional users, this one’s got plenty of options under the hood. Even though it’s a little bigger than our budget pick, it still needs only 21-1/2″W x 24″D x 18″H of workspace. The Neutec® Plus 150 has a larger opening in the weld chamber that won’t give you any trouble if you want to work with larger pieces. For a product in its price range, it offers great optics and a decent amount of memory cell capacity that allow you to save up to 32 individual, specific configurations for your most-used applications.
It integrates the advantages of standard welding head and swing head into one. Material is added to the weld joint usually in the form of metallic wire or powder. Materials are joined without the addition of extra filler materials which requires the highest level of fixturing and joint preparation.

If the accuracy of the workpiece assembly or beam positioning does not meet the requirements, it is easy to cause welding defects. Because the energy comes from the photon beam, there is no physical contact with the workpiece, so there is no external force applied to the workpiece. Because the small hole filled with high-temperature steam is conducive to welding pool stirring and gas escape, resulting in the generation of non-porous fusion penetration weld. When laser deep fusion welding, the phenomenon of small holes is always present, regardless of the depth of the weld. When welding, the focal point position is critical in order to maintain adequate power density. In order to improve the protection effect, additional lateral blowing can also be used, that is, through a smaller diameter nozzle will protect the gas at an angle directly into the deep fusion welding of small holes.
Preventing thermal cracks is one of the key technologies for laser welding of aluminum alloys. In order to improve the quality of the weld seam, continuous laser welding is used. The weld seam surface is smooth and uniform, free of spatter and defect, and no cracks are found in the weld seam.
A simultaneous cut/seal may also be carried out for packaging or bag-making purposes by controlling the laser-beam power distribution to cut two films in contact while leaving a welded region at the edge of the cut. In the following examples, costs are calculated at 70 percent beam-on time. The three types of welding heads used for most laser welding applications are a transmissive head, a parabolic head, and a remote or scanning head. A transmissive head having a removable focal lens often is used for simple, low-power applications. These heads are easy to use and configure with different focal length lenses. On the downside, a focal lens is more susceptible to damage from weld spatter and is harder to cool efficiently because it can be cooled only from the sides.
Compared to common laser welding, HW-A wobble laser welding best for wider seam welding and deep penetration welding. This process is characterized by high efficiency and high welding speeds. This process is used in applications requiring deeper welds or where several layers of material have to be welded simultaneously. For example, our budget pick, the Neutec® PulsePoint™ Plus 20, delivers up to 20 joules of output energy. Although 20 joules will be enough for most laser-welding applications, especially on silver, if you need to work on platinum and titanium, for example, you’ll want a more powerful tool.
