Welding is one of the most popular methods of joining elements not only from metal materials, but plastics also. Their great diversity, chemical structure and physical condition in which they are at the temperature of use has a significant impact on the quality of the joints made. Welding is a particularly useful method of joining, for example, during the welding of packaging, where biodegradable plastics that dominate in this technology, for example with aluminum foil, dominate. This article reviews the methods of welding plastics including biodegradable materials.

“…Lactide acid is an intermediate product which is in turn obtained in the bacterial fermentation of starch derived usually from corn or in the course of milk processing [10][11][12][13][14][15][16][17][18][19][20][21][22][23]. PLA is used in the packaging industry, medicine and agriculture [10][11][12][13][14][15][16][17][18]. It can be recycled and processed many times [21].…”

Polypropylene (PP) is commonly used in the polymer processing industry. Its feature is a good chemical resistance, it is non-toxic and not harmful to people. Polypropylene is widely used in the manufacturing of food packages, laboratory and medical equipment, electric cables insulators, automotive parts, toys and furniture. The application of this material enables us to obtain complicated shapes of big surfaces. It is also highly recyclable. Polylactide (PLA) is a product of the so called “green chemistry” because it is obtained from the renewable raw materials (biomass). As its price is higher compared to the traditional polymers, its repeated use (recycling) is of high interest. Due to the same reason (cost) the mixtures of PLA with other polymers are applied. In this paper the results of testing the PP/PLA mixtures of various mass ratio of the components are presented. Technical terms of preparing and processing such mixtures have been practically tested. Also the mechanical strength was determined based on the static tensile tests. The results showed that those mixtures can be repeatedly processed. Even five-times reprocessing does not cause essential drop of mechanical properties

The article presents an analysis of the implementation of a selected element of the traveler safety system used in road transport. The results of metallographic tests were presented, and the state of stress introduced to the casting by means of forming the element by means of plastic forming was analyzed. An analysis of the manufacturing process was carried out indicating the risks that may lead to cracks in the material structure. Possible causes of founding defects were pointed out and possible technological solutions were pointed out in order to avoid them.
