When it comes to applications in resistance and laser welding, hard brazing or ultrasonic welding of metal parts, global OEMs rely on the experience and expertise of TECHNAX.

Metal parts and combinations such as nickel, copper, aluminium and steel or special alloys can be reliably joined using various welding and brazing technologies. Whether in the automotive industry, electrical engineering, aerospace or other industrial sectors, welding processes with minimum heat input, good transition resistance and maximum connection safety are mostly required. Further requirements are splash-free welding or welding without direct deformation of the assembled part.

Customers positively evaluate TECHNAX long expertise in hot-crimping, microwelding, or compacting of cables and braids ends.

TECHNAX know-how also includes the feeding of brazing material in between parts for hard-brazing applications for example. This technology is often referred to as resistance welding.

In addition, we have an extensive experience in the conception and fabrication of tools, for various functions like punching, bending or screwing. Precise feeding and positioning of small components
like silver tips or small contacts is part of our our scope as well.

A very fast growing market is the e-mobility for electrical cars. Safe thermal connections are required for the cars powertrain system. Resistance and laser welding as well as combrazing and ultrasonic welding are used here. Experience together with a competent R&D department in thermal joining of heterogeneous and homogeneous metals into electrical assemblies are the prerequisites for the optimal implementation of high-quality products from development throughout the pilot phase and prototypes to series production. This guarantee extends from the development phase through the pilot and prototype stages to mass production.

The individuality in assemblies designs and steady goal of size reduction presupposes high expectations in the conception of welding machines. Feeding, positioning and checking each single part in an assembly is quite challenging. The subsequent joining through micro-welding or hard-brazing builds further requirements in regard to design of the welding tools and heads and brazing material feeding too.

Furthermore, each process step must be monitored during production.

Documentation of the welding parameters for each sub-assembly is very frequently required by customers.
