The meeting was opened with a lecture delivered by M.Sc. Eng.  Adam Termina, who addressed the efficiency of mechanised hybrid PHW welding compared with MAG technology, demonstrated the potential of hybrid solutions to increase production efficiency. In turn, Dr Eng. Michał Urbańczyk discussed in detail the welding processes for double-layer pipes of the 3R12/4L7 grade using laser technologies.

M.Sc presented the topic of increasing resistance to abrasive wear using powder plasma surfacing. Eng.  Mateusz Sowa. Then M.Sc. Eng. Maciej Pietraszewski presented issues related to testing the properties of 3D-printed elements using the WAAM (Wire Arc Additive Manufacturing) method.

 In the next part of the seminar, M.Sc. Eng. Marcin Zwier discussed the analysis of selected standards and regulations in the area of hard and soft soldering, emphasising the importance of process compliance with current regulations.

An important point of the program was the speech of Dr Eng.  Tymoteusz Gajewski, who presented issues in the field of fracture mechanics and fracture resistance of materials, including CTOD testing of structural materials. 

 The importance of laser technologies in industry is growing.

The speakers emphasised the growing importance of laser technologies in industry. As indicated, their use allows for increased efficiency in production processes and cost reduction, among other things, by shortening the time required for component preparation and the welding process itself. The presentations showed a wide range of applications – from the automotive industry, through shipbuilding and railways, to the energy and transmission sectors.

Various types of laser welding are also discussed, including classic laser welding, twin-spot welding, filler-metal welding, laser brazing, remote welding, and hybrid laser and electric arc welding (HLAW).  The technology of laser powder cladding (LMD – Laser Metal Deposition) was also presented, which is finding increasingly wider application in industry.

The conclusions presented at the seminar indicate that the development of modern welding technologies – especially laser and hybrid ones – is a key direction for increasing production efficiency and improving the quality of manufactured components.  The meeting was not only an opportunity to exchange knowledge, but also to establish contacts between representatives of science and industry.

 The seminar confirmed that the Industrial Spring at Targi Kielce is an important platform for presenting technological innovations and dialogue between experts from various industrial sectors.
