What is Laser Welding?

Laser welding is an innovative technology that revolutionizes the industry.

Laser welding is a material joining technique that uses the energy of the laser beam to melt the surfaces to be joined. The laser beam, precisely concentrated, allows you to obtain small welding spots, guaranteeing a clean and controlled weld.

Thanks to its high precision laser beam, it allows you to join materials efficiently and with high quality.

This methodology has significant advantages compared to other traditional welding techniques. With a wide range of industrial applications, laser welding offers high flexibility and versatility.

Let’s discover its operating principles, materials and applications, procedures and techniques, systems and equipment, safety and precautions, as well as future developments that characterize it.

Advantages of laser welding

  • High precision: laser welding allows you to obtain high precision joints, thanks to the accurate focusing of the laser beam.
  • Welding speed: this technique allows for rapid welding, as the laser beam can be easily controlled and modulated.
  • Less thermal distortion: Thanks to the targeted focusing of the laser beam, laser welding minimizes thermal distortion in materials, keeping their original shape intact.
  • Welding quality: Laser welding offers high quality welding, without the need to use additional filler materials.
  • Versatility: This technology can be used to weld a wide range of materials, including metals, plastics and wood.

Applications of laser welding

Laser welding finds application in various industrial sectors, such as automotive, electronics, aerospace and many others. It is used for the production of mechanical components, electronic circuits, microwelding and much more. Its high accuracy and versatility make it an ideal choice for many specialized applications.

Operating principles of laser welding

Laser welding is a process of joining materials that uses the energy of a focused laser beam. This beam, of high intensity and precision, is used to melt the surfaces to be welded. The laser energy is absorbed by the material, generating heat that causes the parts to be joined to melt and solidify.

Technology and processes used in laser welding

Laser welding technology is based on several processes, including transmission welding, heat conduction welding and light conduction welding. Transmission welding occurs through the absorption of the laser by one of the materials to be welded, while thermal conduction welding uses the heat generated by the laser beam to melt both materials at the same time. Light conduction welding, on the other hand, uses a filler material which, heated by the laser, melts and forms a solid joint between the materials to be welded.

Thermal conduction and light conduction welding

  • Thermal conduction welding is based on the principle of heat conductivity. The laser is focused on the junction area between the materials, generating heat which propagates through thermal conduction and melts the surfaces to be welded. This process is particularly suitable for welding materials with high thermal conductivity.
  • Light conduction welding, on the other hand, uses the light energy of the laser to melt the filling material found between the parts to be welded. This filler material, usually an alloy or solder wire, is melted under intense laser light, creating a solid connection between surfaces.

Knowledge of the operating principles of laser welding is essential to understand the applications, advantages and potential of this advanced technology. Laser welding offers great precision, speed and reliability in production processes, making it increasingly widespread in various industries.

Materials and applications for laser welding

Laser welding offers a wide range of possibilities thanks to the most suitable materials used. These materials must have certain characteristics to obtain optimal welding results. The most common materials for laser welding include stainless steel, aluminum and titanium. These materials are chosen for their thermal conductivity, mechanical resistance and adaptability to high temperatures.

Laser welding for the production of tools and molds

Laser welding is widely used in the production of tools and moulds. Thanks to its precision and high welding speeds, it is possible to obtain high-quality joints that guarantee the durability and efficiency of the tools. Laser welding allows you to repair and strengthen damaged parts of tools, extending their useful life and reducing replacement costs.

Industrial applications of laser welding

Laser welding finds numerous applications in the industrial sector. It is widely used in the automotive industry for the production of bodywork, chassis and structural components. Furthermore, it finds use in the aerospace industry for welding critical components such as tanks and light structures. Other industrial applications include energy, electronics and medical device manufacturing.

Laser welding systems and equipment

Laser welding requires specific systems and equipment to guarantee a precise and high-quality result. Below, the main components and tools used in the welding process are presented.

Machine tools and laser welding equipment

  • Laser Source: Key component of the laser welding system, the laser source emits the high-power laser beam used for the welding process.
  • Movement and positioning: movement systems allow you to control the position and movement of the piece to be welded with respect to the laser beam.
  • Cooling devices: These devices ensure that the laser source and other components do not overheat during the welding process.

Torches and accessories for laser welding

  • Laser torch: the laser torch is the element that concentrates the laser beam on the welding area. It is designed to ensure optimal precision and stability throughout the process.
  • Welding wires: Welding wires specifically for laser welding are used to provide the necessary filler material at the welding point.
  • Protection system: to ensure operator safety and prevent the irradiation of the laser beam in unwanted areas, protective devices such as shields or protective glasses are used.

Tables and support tools for laser welding

  • Work Table: The work table provides a flat, stable surface on which to place the workpiece to be welded. It must be heat resistant and have a fixing system to maintain the stability of the piece during the welding process.
  • Collets and Clamps: These holding tools are used to securely hold the workpiece during welding, ensuring precise and secure positioning.
  • Measuring tools: To ensure the accuracy of the welding process, measuring tools such as alignment calipers, micrometers or lasers are needed.

In addition to these components, there may be other specific accessory equipment based on the needs and applications of laser welding. The correct selection and use of these systems and equipment are essential to achieve excellent welding results and meet safety regulations.
