Laser welding - complex guide

What application does laser welding have in production?

Laser welding is becoming increasingly popular in many production branches, from ship and car production, covering the medical sector to electronics or jewelry and furniture production. In addition, most of the laser welding machines installed in the last decade are equipped with fiber-like lasers.

Fiber laser welding

Laser welding begins by melting the contact area with a concentrated high-power light radius. This is one of the most modern ways of connecting metal and alloys, allowing to weld details of any thickness and shape.

Efficient and easy-to-use laser welding equipment has a very wide range of applications:

• Welding of butt joints;
• Welding of overhead joints;
• Welding of corner joints;
• Spot welding;
• The blur allows you to adjust the shape of the parts.

Laser welding equipment

Laser welding equipment can be used for deep welding, ensuring a high strength of narrow welds, as well as the connection of fast thin-walled parts and elements requiring aesthetic weldings without further processing.

Whether it's a mobile or stationary solution, compact or complex, allowing you to implement a wide range of projects, or a small precision laser welding device for jewelers or dental technicians, they all meet exceptional quality and have features that will facilitate work.

Fiber laser welding allows not only to meet various welding needs, but also allows to reduce the number of operations performed. In addition, high laser beam power speeds up the welding process and improves productivity. An additional advantage is the low cost of operating this technology.

Laser welding

In many production processes it is increasingly important to achieve an image of strong, visually flawless stitches. Laser welding systems ensure the accuracy and performance required in a large-scale industry, as well as the flexibility and tenderness required for welding small parts.

This technology is also widely used in large-scale automated production and in industries such as automotive, aerospace, sanitation or electronics, and the range of technology applications is expanding further, along with continuously evolving technologies.

Laser welding is economical, reliable and safer than traditional methods, and welded parts do not require additional mechanical processing. We can highlight the main advantages of this technology:

• Reduced heat introduction, thanks to which the deformation of the welded part is very small;
• Minimum heat-exposed zone;
• Uniform, repetitive seams;
• Narrow and attractive-looking welding connector;
• High strength seams;
• Easy automation of processes;
• High degree of accuracy and control;
• The possibility of welding various materials;
• The use of an additional wire is not necessary;
• Flexible manipulation of light rays;
• Incomparably faster than other methods, this increases productivity.

Complex connections

Laser welding technology allows welding very complex connections and can weld steel, aluminum and other alloys in places where it would be extremely difficult to achieve with the help of traditional welding techniques.

Precision accuracy

One of the main advantages of laser welding is maximum accuracy. It is a highly accurate technology, so it can be used to weld the smallest parts without risking damage.

Minimum thermal deformations

Laser welding machines use energy concentrated in a very small area, which allows not only to process without contact, but also to reduce the thermal load and deformation of parts. For this reason, this is an excellent solution for companies working with stainless steel.

Uniform seams

Manufacturers prefer laser welding equipment, because it allows to get uniform and repeatable seams. It is much faster and more versatile welding technology compared to traditional ones.

Strength of the connector

Laser technology allows you to extract very strong and high-quality seams, welding with and without access, and the welding process itself is very clean. For these reasons, laser welding is often chosen by medical industry manufacturers, for which the safety of medical devices and their parts is the most important.

Industrial adaptation

The advantages of laser welding equipment are appreciated by the furniture, automotive, shipbuilding, aviation, medical and electronics, photovoltaic, defense industry.

Laser welding is an extremely flexible technology that expands the capabilities and parameters that distinguish it against the background of traditional solutions. Therefore, it is not at all surprising that day-to-day laser welding begins to be used in other industries, which use laser aparaus in other, even more interesting areas.

What power welding laser source to choose?

Three models of FANUCI laser welding equipment are available:

• 1000W - recommended for stainless steel and carbon steel tins from 0.5 to 2.5 millimeters. Aluminium up to 1mm.
• 1500W - for tins up to 3,5 millimetres thick, aluminum up to 2mm;
• 2000W - tins up to 5mm thick, aluminum up to 3mm.

Each source power allows you to weld using an added wire, but for those who want to boil a lot with wire, we recommend choosing more powerful sources of 1500W or 2000W.
