Steel welding is used to a great extent, especially in the automotive industry. We offer highly professional spot welding equipment for this purpose, which ensures the best possible result in series production. Our products are characterized by the following properties:
With the combination of
Matuschek offers a complete package, which not only promises the implementation of all these requirements, but also implements them safely!
Because only if these requirements can be reliably implemented, savings over the production cycle can be achieved which exceed the additional investment at the beginning many times over. Do the math yourself. We look forward to helping you save.
The subject of liquid metal embrittlement is currently once again a highly topical issue in engineering circles. After the reduced use of TRIP steels from car body construction, which were characterized by strong variations in rebound behavior after forming and therefore tended to have poor fits, and were therefore strongly affected by liquid metal embrittlement, for some time now it has been high-alloy and ultra-high-strength galvanized steel grades with yield strengths > 1 000 N/mm² that have brought the subject of liquid metal embrittlement back into the limelight.
Due to the high strengths, the usual disturbance variables known in series production, such as sheet bounce due to poor fits and misalignment of the electrodes to the sheet, lead to increased stress on the sheet surfaces with simultaneous thermal stress.
Meticulous care in forming, plant design and fixture and clamping technology are the so far known ways to reduce cracking due to liquid metal embrittlement of the steel.
The ServoSPATZ technology (combined control of the welding current and control of the electrode axes in one device (combined control)), which has been proven for more than 10 years, could be extended by the NC technology, the adaptive control method ServoMASTER and NUGGETIndex NC®. This significantly reduces or completely avoids the formation of cracks.
