Photonweld

[Jonathon Burnside]

TheA-Pro-T55 power source has many pre set functions for welding Mild steel, Stainless steel, Inconels, Aluminium and brass and User memories to save your own parameters. The photonweld range range of handheld laser welding machines are 230v single phase machines needing a maximum of 16 amp supply.

The lasermach Feed wire feed for Laser welding units ensures superior quality and high speed Laser welding with perfect precision. For this purpose, the automatic wire feed has a fully digital control, a tacho-controlled feed motor, and a 4-roller high-precision feed for precise wire feeding.

The Lasermach cold wire feeder ensures fool-proof feeding and reliable results without spatter in combination with the Laser welding unit when the maximum deposition rate is required in Laser welding. It is ideal for all laser welding tasks in which a filler metal is essential.

Our goal is to optimize the beam delivery from the high power laser to the work piece. Since our customers demand high performance, flexible solutions and no loss of power or time, we continuously work to improve and increase the possibilities of laser welding technology.

The use of collimated QCS interface greatly reduces the size and weight of the welding torch,only 595g. The optical design is perfectly matched with the QCS output head, the transmission efficiency is high, and the heat generation is small. In addition, the torch has a built-in swing function that allows the operator to consistently and safely perform high-quality welds throughout the day with dual safety light buttons.

This application program is dedicated for the operation of the PhotonWeld A-PRO provided by Lasermach. PhotonWeld-Connect is an application program for selecting, adjusting, and saving welding conditions, monitoring status of, and checking interlocks, warnings, and alarms in the PhotonWeld A-PRO Series. This application is delivered with the PhotonWeld PRO machines or can be downloaded from your app store. Can only be used on our new PRO machine.

with laserwelding, when dropped on the floor or hit, there is a great possibility that the laserbeam is not accurately located on the centre line anymore. As the laserbeam is only 0.1 mm of diameter, or even smaller, the correct position of it is very important for a good weld. Now with our new app the position of the welding beam can be adjusted with a slider on the screen of your phone!

The currently offered laser welding equipment in the market today is mainly a water-cooled solutions. Their heat is taken out of the laser through the external coolant circulation of the chiller with big ventilation system. PhotonWeld Series focuses on generating less heat in the first step and then reduce the lost energy for cooling. Our super high photoelectric conversion efficiency of 976nm EcolEner-technology Creatively solved this problem. Generating minimal 20% less heat than any other laser source in combination with high efficient inverter driven optimized air cooling system, creates a real sustainable welding machine with high ecological and economical advances compared to any other laser welding machine on the market.

We launched the the air-cooled 976nm technology for the first time in the industry, which generates the drastic reduction of the power consumption and creates perfect portability, and with this winning combination we take the lead in the technical development direction of fibre laser handheld welding machines.

16000 watt power to weld thin sheet materials, with or without filler wire. The photonweld-A1600 power source has 55 pre set functions for welding Mild steel, Stainless steel, Inconels, Aluminium and brass and 18 User memories to save your own parameters. The photonweld range range of handheld laser welding machines are 230v single phase machines needing a maximum of 16 amp supply.

The machine is supplied as a ready to weld package including :- 1600 watt Photonweld power source, laser torch with 5m fibre optic cable bundle, full set of nozzles for differing joint configurations, (butt, lap, fillet, outside corner) spare set of protection windows (10), cold wire feed unit for 0.8 to 1.6mm filler wires, wire delivery tube and 2 OD7 laser safety glasses + 1 OD7 face shield.

The use of lasers for welding has some distinct advantages over other welding techniques. Many of these advantages are related to the fact that with laser welding a 'keyhole' can be created. This keyhole allows heat input not just at the top surface, but through the thickness of the material(s). The main advantages of this are detailed below:

Laser welding is a very fast technique. Depending on the type and power of laser used, thin section materials can be welded at speeds of many metres a minute. Lasers are, therefore, extremely suited to working in high productivity automated environments. For thicker sections, productivity gains can also be made as the laser keyhole welding process can complete a joint in a single pass which would otherwise require multiple passes with other techniques. Laser welding is nearly always carried out as an automated process, with the optical fibre delivered beams from laser diodes or fibre lasers in particular being easily remotely manipulated using multi-axis robotic delivery systems, resulting in a geometrically flexible manufacturing process.

Laser welding allows welds to be made with a high aspect ratio (large depth to narrow width). Laser welding, therefore, is feasible for joint configurations that are unsuitable for many other (conduction limited) welding techniques, such as stake welding through lap joints. This allows smaller flanges to be used compared with parts made using resistance spot welding.

Lasers produce a highly concentrated heat source, capable of creating a keyhole. Consequently, laser welding melts only a very volume of weld metal, and transmits only a limited amount of heat into the surrounding material, and consequently all welded parts distort much less than those welded with many other processes. Another advantage resulting from this low heat input is the VERY narrow width of the heat affected zones either side of the weld, resulting in less thermal damage and loss of properties in the parent material adjacent to the weld.

With lasers, many different materials can be welded or joined, both metallic and non-metallic, and including steels, stainless steels, Al, Ti and Ni alloys, plastics and textiles. Furthermore, taking the example of steels, the thickness of the material that can be welded can be anything from under a millimetre to around 30mm , depending on the type and power of laser used.

Unlike the majority of electron beam keyhole welding operations, laser welding is carried out at atmospheric pressure, although gas shielding is often necessary, to prevent oxidation of the welds.

Laser welding does not apply any force to the workpieces being joined, and more often or not is a single sided process, ie completing the joint from one side of the workpieces. However, in common with many other fusion processes, weld root shielding can be required from the opposite side.
