Welding is the heart of the Leas business. For more than 40 years we have specialized in applying the most advanced technologies available on the market, for a continuous renewal of welding processes.

The attention today extends to the different types of joins between materials depending on the fields of use and materials involved, from traditional alloys to the most ones, with processes ranging from clinching, brazing, to the various welding processes by fusion. For us, process sustainability increasingly becomes a decisive factor for choosing the technologies to be used.

Identifying the most appropriate technologies to optimize processes and increase productivity is the commitment of our design teams.

  1. Resistance welding

    When productivity matters.

    Resistance welding is the clean, preferred welding technology for joining various components of ferrous materials and new generation alloys. The experience gained over the years has allowed Leas to successfully develop specific technological applications also for welding ferrous components and copper alloys.

  2. Capacitive Discharge Welding

    When speed is worth.

    Capacitive discharge welding, also known as Stud Welding (or CD Welding), is the solution for welding various types of copper alloys, yellow alloys in general and steel alloys. In particular, it allows to easily join small and medium size pins, bushings, fastons, studs and small objects on sheet metal, even very thin sheets. The complete welding cycle takes a few milliseconds. Leas offers capacitive discharge welding for applications in the automotive sector or, for example, in the field of accessories or for the production of electrical cabinets. Besides the advantage of faster welding with respect to resistance welding systems, there is the additional ability to produce small batches.

  3. Arc Welding

    When you can count on multiple solutions.

    Arc welding includes different processes: submerged arc welding, used when high quality is a necessity, or electric arc welding processes, for universal use.

  4. Induction welding

    When series production is important.

    It is a special technology that allows modelling various types of metal and to create the joint quickly. It is mainly used in the heating sector for closing the heads.

  5. Laser Welding

    When precision is paramount.

    Laser welding is the pinnacle of technological innovation. It guarantees constant control of the whole process and offers an aesthetically excellent result with the advantage of greater productivity compared to Mig welding. Leas is increasing the use of laser welding in the industrial products sector, where it believes it can offer competitive solutions to increase quality and productivity.

  6. Brazing

    When versatility is essential.

    Brazing is a type of welding used to join ferrous and non-ferrous materials, in particular yellow alloys. Versatility is the most appreciated advantage. Braze welding is indicated when the parts to be joined have very large surfaces or complex geometries, on a large scale or small series, as it does not require high technology. An application example is the production of heat exchangers.

  7. Clinching

    When to choose an innovative and sustainable process.

    Clinching is the new frontier in joining materials, thanks to the innovations introduced in the cold joining process, without the need for additional material. The development of this technology is sustainable and environmentally friendly. It is particularly suitable in the storage sector (racking, shelves), household appliances (washing machines, dishwashers, etc.).
