Press Joining

Press joining (also known as clinching) is a method for connecting metal sheets without having to use a filler metal. It can be classed as both a joining process and a forming process because the connection is achieved by forming the material.

Longitudinal Seam, Spot, Pressure, and Stud Welding

Welding is the process of connecting metallic surfaces by applying heat and pressure. The metals are heated to a pasty state so that they mingle and become connected. We carry out welding using the specified method and:

• Tungsten and metal inert gas welding systems (TIG/MIG)
• Longitudinal welding system
• Pressure and spot welding systems
• A (3-axis) CNC stud welding system

Riveting

is the process of permanently joining two or more parts by compressing a connecting element – the rivet – to form a non-positive (hot-riveting) or positive (cold-riveting) connection.

• Riveting machines

Soldering/Brazing

is a thermal process for joining materials through substance-to-substance bonding. A liquid phase is formed by melting a solder (fusion soldering) or by means of diffusion at the faying surfaces (diffusion brazing). This creates a surface alloy but there is no deep fusion of the workpiece: The liquidus temperature of the base materials is never reached. As the solder/brazing solder solidifies, a substance-to-substance bond forms similar to the one created during welding.

• Hard soldering (brazing) and soft soldering
