Problems of HLAW Hybrid Welding of S1300QL Steel.

This paper presents the results of tests on the fabrication of welded joints in S1300QL steel according to the requirements of ISO 15614-14 and ISO 12932. The butt-welded joint without bevel was made from 350 × 150 × 8 mm sheets. The welding process was carried out at the hybrid welding (laser-MAG) station.

Hybrid Welding (Laser-Electric Arc MAG) of High Yield Point Steel S960QL.

The article discusses the effect of the hybrid-welding process (laser-electric arc MAG ) on the structure and properties of butt joints (having various thicknesses, i.e., 5 mm and 7 mm) made of steel S960QL.

Influence of pigments on phototransformation of biocides in paints.

Biocides are commonly applied to construction materials such as facade renders and paints in order to protect them from microbial spoilage. These renders and paints are exposed to weathering conditions, e.g.

Partition of biocides between water and inorganic phases of renders with organic binder.

The use of biocides as additives for building materials has gained importance in the recent years. These biocides are applied, e.g.
