7th serie aluminium welding

When the mass available to perform a function becomes a strong constraint it is possible to find standard mechanical solutions. The use of 7th series aluminum alloys for welded components is a solution, even with standard welding processes.


7th serie aluminium welding

A year of testing and implementation of welded coupons, weld maturation study, has enabled us to develop welding procedures with obtaining 65% of the mechanical properties of the base material in the weld without using the FSW process.
