1 - PhotonWeld: Laser Welding without material infeed

⇒ Laser Welding without added material : Autogenous Laser Welding

Materials are joined without the addition of extra materials which requires the highest level of fixturing and joint preparation. Since no material is added, it is necessary for the materials to be welded to remain in intimate contact during the welding process. Any significant separation of the materials can result in an unacceptable weld profile. 

Good Fixturing to ensure consistent fit-up of the weld joint is a key to successful fiber laser welding. An important benefit of fiber laser is that the welded joints have an exceptional cosmetic appearance. In some cases, these welds are almost perfectly blended with the surrounding material. Depending on the fixturing and joint fit-up, some welds may have small amounts of concavity (which may not be acceptable for product designs that require fatigue properties similar to those of the base material) or convexity. 

2 - PhotonWeld: Laser Welding with material infeed

⇒ Welding WITH added material : Additive Laser Welding

Material is added to the weld joint usually in the form of metallic wire.

Three reasons for adding material to the weld are:

  1. Joint fit-up: By adding extra material, the joint becomes more tolerant to joint mismatch. Acceptable welds may be produced from joints with less than perfect fit-up.
  2. Weld geometry: Addition of filler metal is used to control the shape and size of the weld. Maintaining a crown (convex surface of the weld) creates a reinforcement which is important for joints requiring mechanical strength and fatigue life in the overall product’s design performance.
  3. Dissimilar metals: Filler metal is added to facilitate welding of dissimilar metals and alloys which are otherwise metallurgically incompatible.

3 - PhotonWeld: Laser Welding of dissimilar metals

Dissimilar Metal Welding - Different metals perfect joining by Fiber laser

As with any welding process, establishing a good fiber laser weld involves a lot of variables.  A material’s weldability is a factor. Most common materials a fab shop will process—be it carbon steel, stainless, or aluminum—have been successfully laser welded for years, using both continuous wave and pulsed modes. Lasers have performed dissimilar-metal welding ( Sample picture is copper joined with galvanised steel by fiber laser welderwithout adding material), and specialized weld joint designs in galvanized material have even accounted for zinc outgassing. Moreover, a multikilowatt fiber laser has been shown to successfully weld even the most challenging of materials, including copper

4 - PhotonWeld: Laser Spot Welding

⇒ Laser Spot Welding - Laser Keyhole Point Welding

Laser Keyhole welding beats conventional spot welding machines on all fronts

Laser spot welding is a non-contact process which uses a laser to create a single weld spot to weld metals together. Lasers are capable of delivering a pulse of light with accurate, repeatable energy and duration. When the pulse is focused into one place – a small spot – (adjustable anywhere from approximately 0.1 to 5.0 mm) on the part, the energy density becomes quite large. The light is absorbed by the material causing a “keyhole effect” as the focused beam drills into, vaporizes, and melts some of the metal. As the pulse ends, the liquefied metal around the keyhole flows back in, solidifying and creating a small spot weld. This entire process just a few milliseconds.Laser keyhole spot welding offers numerous benefits in the right applications, including precise control of penetration depth, a very small beam size for a small heat-affected zone, great consistency, and an extremely fast process.

Most manufacturers are looking for ways to save money and improve efficiency without negatively impacting quality. Manufacturing operations that are using resistance spot welding can reap significant productivity and quality benefits in some applications by converting to laser keyhole spot welding. Lasers can fire many pulses per second, and, by moving either the work piece or optics, allow either separate “spot” welds or a series of overlapping spot welds to create a laser seam weld that can be structurally sound and/or hermetic.

Implementing fiber laser keyhole spot welding can result in a welding process that is three to four times faster compared to resistance spot welding, while also increasing weld quality and repeatability.

However, laser keyhole spot welding may not be the right fit for every job.

6 - PhotonWeld: Laser Cleaning

⇒ What can a laser cleaner clean?

Laser ablation coating removal

Laser coating removal is an ablative process whereby laser energy is focused and absorbed by the surface, resulting in vaporization of the coating with minimal effect to the underlying substrate. This process can be applied to various materials including metal, plastics, composites and glass.

Laser cleaning is a green and environment friendly cleaning method, because laser removal can replace the use of chemical and abrasive cleaning method, this cleaning method will harm the material base and lead to some pollution, meanwhile the laser cleaning machine is a non-contact cleaning process. So there is no secondary waste after the cleaning work.

Laser cleaning is a green cleaning method, it can be used to remove dust and rust in the metal and none metal material. For example, the laser cleaning machine can work on plastic injection molds, rubber molds. And the laser cleaning machine is also a good cleaning tool for metal substrate and product pieces, the laser cleaning system can remove rust and dust and oxide deposition quickly and entirely, and the laser cleaner also clean the resin surface, oil stains, dirt, rust, coating, paint on all kinds of metal, cleaning a rusty grille down to a shiny metal.

7 - PhotonWeld: Laser Deburring

⇒ Parts deburring by laser

⇒ Laser Deburring: Thermal deburring process where a laser beam of lower intensity than in conventional laser cutting and is directed towards the workpiece burrs.

The process: It has been found that laser deburring provides reasonably accurate dimension and minimal size of HAZ, thus minimal material property changes. . Furthermore, for special applications such as burrs around intersecting holes, a situation in which no mechanical deburring tools are effective, laser deburring would have an advantage over conventional deburring techniques.

The method uses a laser for welding with settings similar to the processes used for laser welding. The difference is mainly that the laser beam intensity in this method is slightly lower to reduce the risk of new burrs forming due to heat generation. The focus point is also a bit above the surface to give a wider beam at the point of impact. The laser beam is directed towards the burrs of the workpiece so that they are burned due the intensity of the laser.

8 - PhotonWeld: Edge Rounding

⇒ Edge Rounding: allowing for optimal coating coverage and corrosion protection.

Edge rounding (also known as edge radiusing) is the process of removing the vertical burrs, nibble marks, or scallops on the holes and edges of a deburred metal part. Metalworkers use edge rounding to break the edge of processed components, allowing for optimal coating coverage and corrosion protection.

Metal edge rounding is a versatile process that can be used to support a variety of metalworking projects. Generally, this solution is ideal for creating the best possible finish on laser-cut or machined metal parts. Edge rounding is a fast and efficient way to remove imperfections from parts with sharp edges or holes across many industries, ranging from automotive to healthcare.

Part Strength & Durability

Rounded metal parts will bond correctly with coatings, increasing their surface strength and durability in the process. (This is especially important for high-contact components.) Fully coated parts are more resistant to corrosion, operational wear and tear, abrasion, and many other types of damage

Part Aesthetics

Rounding metal parts allows them to be properly coated and painted, creating functional products with an attractive aesthetic. Metal components free of sharp edges create a perfect bonding surface for paints, reducing the risk of peeling and being forced to reapply paint coatings over time.

Physical & Electrical Properties

Rounded metal parts are compatible with a wide range of protective coatings, including those that support electrical conductivity, heat resistance, and cryogenic stability. For these protective coatings to bond properly, each metal part must be completely free of burrs, scallops, and other surface imperfections.

Applications of Metal Edge Rounding

Metal edge rounding is a versatile process that can be used to support a variety of metalworking projects. Generally, this solution is ideal for creating the best possible finish on laser-cut or machined metal parts. Edge rounding is a fast and efficient way to remove imperfections from parts with sharp edges or holes across many industries, ranging from automotive to healthcare.

One unique application of metal edge rounding is creating an ideal finish on parts with unique cosmetic requirements. For example, a modern edge rounding tool can round the edges of a stainless steel part without marring its surface or tearing off any protective sheeting.
