IK4 analyses the Joining Technologies applied in Advanced Manufacturing

11/20/2018 |<img src="http://www.ik4.es/upload/noticias/img/n_20_11_2018_re.jpg" data-link="" /> The joining of metal and carbon fibre, assembly using high-resistance steel screws or the substitution of adhesives by chemical bonding in the case of differing materials were some of the solutions dealt with during the seminar, "Joining Technologies in the Era of Advanced Manufacture", organised last 8 November by the IK4 Technological Alliance.

The event, which took place in Gaiker facilities – one of the centres belonging to the Alliance – addressed specialists and managed to assemble 72 attendees, among them representatives of many companies of high expertise in the field of advanced manufacture.

The multinational company Aernnova was in charge of opening the session with an explanation on how hybrid metal and carbon fibre joining helps create more efficient aeronautic structures in terms of parameters such as aerodynamics or manufacturing cost reductions.

Following the aerospace firm came the turn of some of the technological centres comprising the Alliance. Azterlan enumerated the key factors to bear in mind during the process of screwing high-performance steels in order to prevent rupture. These entail ensuring the metallurgical and mechanical integrity of materials and inspecting screw-tightening processes, among other concerns.

Meantime, Gaiker presented an alternative to the use of adhesives in joining different materials through chemical bonding. This method, which consists of bonding materials that can be formulated and used as mass additives, manages to counteract the inconveniences of using adhesives, such as the need to prepare the joining surfaces or the waiting times required for effective joining.

On its end, Lortek demonstrated the latest advances and developments achieved in the field of friction-stir welding or FSW for aluminium alloys, such as its use on the different parts of an electric car or in aircraft fuselage sections.

In turn, the Tekniker intervention dealt with the benefits of laser technology in the joining of unlike materials, presenting this method as an alternative to other thermal joining processes due to its high flexibility and precision, among other properties.

In conclusion, a round table was held where attendees were able to debate and air questions for all the speakers.
