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. The use of wire-filled laser welding can greatly reduce the limitations for welding gap. For example, for an aluminum alloy plate with a thickness of 2mm, if no welding wire is used, the sheet gap must be zero to obtain a good weld shape. If a φ1.6mm welding wire is used as a supplementary metal, even if the gap is increased to 1.0mm, the weld can be ensured.
It is suitable for welding optical fiber connectors, microelectronic components, medical equipment, precision parts, etc. You can separate the laser beam by time and energy, or process multiple beams at the same time, and realize multi-station processing, which provides conditions for more precise welding. During this process, the laser beam melts the material and also creates a deep keyhole with approximately 1.5 times the diameter of the laser beam. This keyhole created by the laser welding process is surrounded by the melt. laser welding of stainless steel sheet the laser welding of stainless steel sheet was studied by leapion laser.
But these cutting methods are not perfect, so waterjet cutting and laser cutting were invented later, which are also widely used cutting methods. It turns out that these two methods are also the most effective cutting solutions in the industry. Laser cleaning and surface structuring is a chemical-free alternative to paint stripping, rust removal, and weld-preparation steps such as removal of aluminum silicon coatings.
Laser Ablation is the removal of material from the surface of a part. Large-area ablation examples include paint removal and surface cleaning. Smaller feature laser ablation is used in film patterning, blind-hole and shaped feature drilling as well as localized conformal coating removal. Laser marking is the most versatile marking solution as it allows the material surface to be marked or engraved without surface contact or the need for inks or dyes. We combine state-of-the-art lasers with advanced engineering and application innovation to create laser marking solutions that move your business forward. And, our expert technical and customer support guarantees a customizable and scalable laser marking system that will meet your needs now and in the future.
We serve a variety of manufacturing industries with direct part marking solutions. A new area of application in recent years is the oil screen seam pipe. Copper and brass are cut only when there is a “reflective absorption” device installed on the system, otherwise, the reflection will destroy the optical components. On the other hand, the molten oxide and the melt are blown out of the reaction area, forming an incision in the metal. Air can be supplied directly from the air compressor, so it is very cheap compared to other gases.
Fiber Laser cutting equipment can cut stainless steel below 4mm, and can cut up to 8 ~ 10mm thick stainless steel in laser beam if add oxygen. This video displays the welding process of MORN auto laser welding machine for brass, ss, and new energy aluminum battery. The optical fiber transmission laser welding machine has the advantages of good beam quality, fine light spot and flexible installation.
Since there is no tooling cost, the laser cutting equipment is also suitable for small batches of parts that can not be processed previously. 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. Fiber laser technology allow users to easily weld 0,05mm (.002”) away from the most complicated and intricate component parts without damaging heat sensitive materials. All of this changed with the advent of high-power continuous wave and quasi-continuous wave fiber lasers with a near infrared wavelength and ability to control with high speed and high resolution. Fiber laser system manufacturers, thus, have developed new hardware that makes new product applications possible.
