Welding and laser welding
Thermal joining technology using welding and laser welding makes up a large part of our production. Laser technology stands out here. This can be used to join individual components at high speed and - above all - extremely precisely. Other advantages include low thermal distortion, even in the case of really thin materials, and the strong, smooth weld seams, which are free from grime and oxides thanks to the use of inert gases such as nitrogen, helium or argon, and do not normally require post-treatment. For these reasons, this method has been used successfully in the automotive and automotive supplier industries for many years, and the sector is a pioneer when it comes to innovative applications in this segment.
Welding in conjunction with other joining techniques
HMT also uses MAG/MIG welding and resistance welding. When assembling our components, we combine welding with other joining techniques such as bonding, riveting, and screwing. We have the right machines - often equipped with robots - for thread forming, processing self-piercing rivets and blind rivets, and flow drilling.
