Joining Laboratory

Industrial studies concerning assembly technologies are at the very heart of our know-how at Institut de Soudure. The Joining Laboratory was established in order to meet the needs of companies in terms of innovation and competitive edge, as well as in order to take part in major research programmes.


With that prospect, it has concentrated at Yutz and at Goin in Lorraine, the very latest equipment for TIG, MIG, MAG, electron beam, laser, laser hybrid, friction-stir welding and diffusion brazing.



The Assembly Platform provides concrete solutions to companies who wish:

To produce prototype parts

To qualify filler metals

To study the risk of cold or hot cracking of an assembly

To determine and to optimise welding or brazing parameters

To increase the productivity of a welding operation

To establish the operating weldability limits of a material

To evaluate the benefits of innovative welding or brazing technologies for a particular application



Institut de Soudure is constantly investing in order to supplement its welding assets. Currently, it is able to implement the following processes:

Conventional welding: coated electrode, TIG, MIG, MAG, immersed arc;

Conventional in an updated version: CMT, TOPTIG;

Brazing: by torch, vacuum oven, induction;

Friction-stir welding (FSW) in a dedicated unit at Goin;

CO2 laser, YAG laser, electron beam, hybrid laser/MAG and laser/TIG processes.

The laboratory also has the facilities required for conducting weldability tests:

Standardised tests, such as Tekken, Lehigh, CTS, G-bop implant method, measurement of the diffusible and total hydrogen content, in order to study cold cracking.

Varestrain test and self-clamped tests, in order to study hot cracking




The Assembly Platform, which is part of the Materalia network, contributes to numerous projects:
