Plastic Projection Welding

Projection welding is usually performed using a special band of near-infrared lasers, which can travel through most colourless polymer materials. The welding process occurs on an overlapping lap structure: a suitable colouring (absorption) layer is superimposed under a transparent thermoplastic layer. The laser beam passes through the first layer of material, and the absorption layer at the junction of the two layers absorbs the laser beam radiation and completes the welding.

Application fields

Automobile industry, Pharmaceutical industry, Microfluidics industry, Packaging industry, Communication industry

Technical Specifications:

Laser Peening is a process in which a laser beam is pulsed upon a metal surface, producing a planar shock wave that travels through the workpiece and plastically deforms a layer of material. The depth of plastic deformation thus resulting in compressive residual stress is significantly deeper than possible with most other surface treatments.

Laser energy can be used to induce residual compressive stress deep into the metal’s surface layer. The Laser Peening process employs laser-induced shocks to create compressive residual stress of over 0.040 inch (1 mm) deep with magnitudes comparable to shot peening. This provides a damage-tolerant component that is more resistant to various forms of stress-related failures.

Laser Peening typically provides 4x or more the depth of residual compressive stress obtained by shot peening. Deeper levels of compressive stress provide greater resistance to fatigue and corrosion failure.

This makes Laser hardening cleaner and more readily mobilised than traditional heat treatments.

Any ferrous metal (steel or cast iron) which would normally be hardened by more traditional methods like flame or induction hardening, can be hardened with a Laser. Laser hardening is more versatile than flame hardening ore induction hardening.

Laser hardening provides reliable, repeatable, non-contact and energy-efficient heat in a minimalamount of time. For hardening, laser beam provides the necessary control and accuracy tofocus the heat to a specific area of the part. The laser is suitable for the integration in alreadyexisting manufacturing equipment’s and production lines.

Apart from the traditional hardening process, laser hardening offers a range of applications for tasks which couldn’t be solved hitherto optimally for example for components with special forms and special functional surfaces (survey of the hardening tracks):

Selective hardening of single work piece surfaces. Here a selective hard surface arises with a tough center and uninfluenced areas in the direct neighborhood.
Hardening tracks at cutting edges, guide tracks, grooves and free mould surfaces withcontinuous crossing geometry
Good hardenability of surfaces which are difficult to reach such as craned grooves, flutesand interior surfaces
Dot hardening at naps and in blind holes
Hardenability of thin, warp-prone parts by a selective, quick heat input at an extremely shortdwell time.

Laser hardening is a method aimed at improving component wear behaviour.

During laser hardening, also known as surface layer hardening, the energy from the laser beam is applied directly to the component surface. The surface layer is heated up to the hardening temperature (>1000°C) in a reduced area within a very short time.

One advantage of using a laser is that the amount of heat input is comparatively low, so heat is transmitted into the base material relatively quickly. Self-quenching is produced as a martensitic structure is formed and the hardening layer is ‘cooled.’

A very tough, fine-grained structure is created thanks to the high heat-up rate during laser hardening. The risk of cracks forming is very low thanks to self-quenching. The precisely focused energy ensures that the component is subject to a comparatively low impact from heat, bringing a great advantage in minimum quench distortion.

Cleaning with a laser is precise and it comes with high repeatability. The dry and touchless process does not damage the underlying substrate and eliminates the use of hazardous and expensive consumables such as chemicals or blasting media.

a. Damage-free removal of surface coatings

Glove boxes provide a controlled inert atmosphere for manufacturing and assembly processes. Inert is a leading provider of Laser Glovebox Systems along with glove box accessories, including both integrated and retrofit gas purification units, process ovens, analyzers, vacuum equipment, and much more. Inert glove boxes with integrated laser welders can be used in a variety of applications including but not limited to…
The glove box for laser welding

In the knowledge that the ambient air is likely to alter the mechanical characteristics of the metals to be welded, laser welding in the glove box will allow you to operate in a safe atmosphere. In this enclosure, the welding area is surrounded by a shielding gas such as argon, helium or a mixture of these two gases in order to protect it.

The role of the glove box for welding
The gas purification unit controls the moisture and oxygen content in ppm to ensure that the strength and quality of the assembly comply with current standards. The role of the glove box is, therefore, to confine the area away from the air and prevent the propagation of these protective cases. There is a reduction in the heat-affected zone (HAZ), less coloration on the parts to be assembled, better mechanical resistance of the weld over time and greater precision. You avoid deformations while saving time. As a bonus, it becomes easier to weld the most difficult-to-access places or extremely thin surfaces with this equipment.

Ohio Laser has expanded its welding capabilities with the addition of a robotic fibre laser welding cell. Robotic laser welding offers many cost-saving advantages to the customer. It can reduce the overall weld time, decrease secondary processes (grinding, straightening, finishing) and eliminate the use of filler material. Laser welding increases weld tensile strength which creates a higher quality part or assembly.

Our laser welding team can provide custom engineered solutions for your parts and assemblies. We have an extensive background in welding and can take any GTAW (TIG) or GMAW (MIG) designed part and make minor modifications for better laser welding processing. Often, laser welding can replace bending operations for a higher quality, faster and more repeatable process. This technology not only increases throughput but also improves accuracy. Laser welding improves form, fit and function while reducing labour, increasing material utilization and improving the aesthetics of your part or assembly.

Working with laser welding experts at the MTC, Royal Enfield has successfully completed a program to improve consistency, increase throughput and reduce manual input in the manufacturing process. The laser welding cell at the MTC is equipped with a range of welding and cutting head options and is capable of handling large and heavy parts with ease – the laser processing head being carried on a 6-axis robot, which is integrated with a multi-axis manipulator.

Laser welding benefits:

The main benefits of the laser technology versus the previous welding processes are:

Higher productivity: Welding speed has increased between 4 to 8 times depending on the application.
Precise working: With exact placing of the energy spot. High repeatability.
Small focus spot diameter and higher power density on the workpiece with deep penetration welding.
High weld depth ratio: Through deep penetration welding.
Possibility of welding: Of complicated joint geometries and very different geometrically components.
Low total heat application: Resulting in minor microstructure changes and narrow heat-affected zone.
Generation of high aesthetic quality welds.
There’s Minimal thermal distortion of the workpiece.
It yields low post-weld operation times and costs.
Higher process flexibility due to large working distance with good accessibility.
The resistant capacity of storage closet hangers has been increased by 5% compared to the previous components welded with conventional welding processes. This is possible while reducing the welding cycle four times.

Fundamental

With the Scanner Welding System, the laser beam of the solid-state laser is guided to the 3D laser scanner by means of a fibre optic cable and precisely directed to the component via the collimating, focusing unit and scanner mirrors that are integrated in the scanner. Highly dynamic galvanometer drives guarantee a short positioning time. Non-productive times are reduced to a minimum. This method is particularly suitable for 3-dimensional components, such as car front seats, car doors and other structural parts, which have a high number of joint connections

REMOTE LASER WELDING – SYSTEM TECHNOLOGY

We deliver system technology specially adapted to the remote laser welding process.
Highly dynamic rotary indexing tables in combination with a sophisticated, fast lock system ensure minimal downtime and thus extremely high laser ON times.
We attach particular importance to the regulated aeration and venting technology within the laser welding cell – another important component for a successful laser process.

We have such experience on this project. Most customers choose automatic laser welding machines for solenoid valves. It can come true automatic welding working with a rotary axis. MLS has its own design team, where according to the customer product to do different fixture designs. Even it is fully automatic.

Another a distinct advantage of laser welding over other methods is that lasers can weld a greater variety of metals such as high strength stainless steel, titanium, aluminium, carbon steel as well as precious metals like gold and silver.
With laser welding, welds are much more accurate and finish is superior as is strength. The manufacturing process is therefore excellent for fine components and it can be used in areas where there is limited access. Lasers enable precision and quality were required for fine components.

The Zenna Plateweld is equipped with one or two laser heads. With the use of two laser heads, the welding time is significantly reduced.

The MLS Plateweld support a plate-width of 1.500, 2.000 or 2.500 mm wide, the length is basically unlimited. For the transport of the pillow plate MLS supplies in and outfeed tables. For the heavier panels, we use motorized tables.

The system is designed in such a way that one operator can perform all necessary tasks.

SYSTEMS FOR TAILOR-WELDED BLANK APPLICATIONS

Designed for high-output blank production and equipped with high power, high precision linear motors that drive the main laser welding focus head and all clamp motions, Wayne Trail’s linear and non-linear weld stations and systems outperform any other blank welder on the market.

When used with one of our precision-edge prep systems, these laser weld systems will produce production quality laser butt welds faster than normal weld speeds in most blank thickness combinations, including same-gauge applications because of the superior blank fit-up and reduced eject/reject rates. A stable weld environment and intimate fit-up provided by the edge prep process greatly enhances process monitoring capabilities.

Our laser weld gantries require minimal maintenance or setup. Extremely robust and durable, they are a welcome addition to the factory floor. CDRH Class 1 compliance is standard, as is the high-flow fume-evacuation-and-filtration system. This system increases the time between cleaning intervals, optimizing uptime and system availability.
