A little bit of history …

FOXT s.r.o. was founded in 2010, and its primary scope of business was the implementation and administration of quality systems in welding, welding supervision, inspection, nondestructive testing, training and consulting in welding activities. The founder, manager and sole employee at that time was Ing. Michal Michajlec who in just a few years achieved the top qualifications or, more precisely, certifications in welding and in some methods of nondestructive testing. Thanks to its significant experience and know-how, the company started providing support to customers in all sectors of industry.

In February 2017 the company moved into an industrial park in Prague 9 - Horní Počernice where, as a part of its further development, it started welding production. The goal was to make good use of and exploit the knowledge gained so far in welding and, in particular, to supply high-quality welded products to the market. The company received a quality management system certificate according to ISO 9001:2016 and also recognized certificates in welding according to EN ISO 3834-2, EN 15085-2 (CL1), EN 1090-1 (EXC3).

What are our goals?

Our goals are to produce welded components of the highest quality and to maintain complete customer satisfaction. In line with this goal, we would like to improve and develop our quality system, so it is intuitive, transparent, and perfectly represented by the quality of our products. We also plan to expand our production capacities by adding more specialized technical equipment.

What are our production capabilities?

Although we are still a small company, our production facilities, with an area of approximately 300 square meters, offer 3 shops for manual welding and 1 shop for the fully mechanized welding of long linear welds. In these shops we have state-of-the art arc welding equipment by Fronius for welding using the methods MIG (131), MAG (135) and TIG/WIG (141), and also the Siegmund system 28 welding tables and the necessary jigs. The maximum dimensions of our welded products are 2000 x 1000 mm with a weight up to 1000 kg.

Our other technologies which complement welding include cutting with a gravity-feed band saw (275/230) and manual grinding. Other technologies for ensuring the complete supply of welded products are outsourced, using our broad network of trusted partners.

Research in the arc welding of aluminum alloys

The welding of aluminum is not easy. It requires very good technological preparedness and a high level of knowledge in this field. We can weld aluminum, because we have the proper equipment and the requisite know-how. We work with the Technology Institute of the Faculty of Mechanical Engineering of the Czech Technical University (ČVUT) in Prague. We work alongside a postgraduate program researching the arc welding of aluminum products for rail transport.

What do we research?

In the process of welding aluminum alloys such as Al-Mg together with Al-Mg- Si, we often encounter common problems such as weld porosity, susceptibility to hot cracking, the decline of mechanical properties, a high linear expansion coefficient, etc. We have to expect these problems when welding aluminum alloys and use the appropriate procedures to prevent the occurrence of inadmissible defects. What we do is also related to this issue. It concerns the research of the effects of anodic oxidation on the quality and mechanical properties of welding joints in aluminum alloys Al-Mg and Al-Mg-Si made by arc welding.
