W artykule scharakteryzowano wpływ wybranych parametrów procesu wytłaczania i środowiska pracy na jakość wytworzonych rur. W celu określenia częstotliwości i przyczyn występowania wad wytłoczyn wykorzystano takie narzędzie doskonalenia jakości, jak diagram Ishikawy. Zanalizowano 10 dominujących wad powstałych podczas procesu wytłaczania. Podjęto próbę ustalenia intensywności występowania wad oraz możliwości ich eliminacji.

In article was characterized the impact of extrusion process parameters and work environment on the quality of manufactured pipes. In order to determine the causes of defects of extrudates was used for quality improvement tools such as Ishikawa diagram. They analyzed 10 dominant defects occurring during the extrusion process. An attempt was made to determine the intensity of defects and their possible elimination.

The article presents the selected results of strength tests on the effectiveness of bonding high-alloy steel 1.4310. Sheet steel is one of the materials that are difficult to activate energy. Effective joining of it is difficult, requires selection of the appropriate bonding technology. The paper focuses on the comparative tests of shear strength of one-single lap welded and bonded joints. The welding process was performed on 3 groups of samples TIG welding and argon, where the variable value of the welding process was current: 60A, 70A, 80A. The adhesion process was performed in 6 groups of samples which differed in the method of surface preparation and the type of the adhesive. Adhesive joints were made by using adhesive of epoxy resin and a hardener: Epidian 61/TFF at a mass ratio of 100:22 and Epidian 61/IDA at a mass ratio of 100:40. As a way of surface preparation applied 3 different, but simplified and environmentally friendly methods of surface preparation: degreasing with using cleaner Loctite 7061, abrasive machining with P320 and degreasing and grinding with abrasive T800 and degreasing were used. Make joints and curing the adhesive joints were carried out at ambient temperature. Analyzed the joints were tested destructive – which set out the shear strength, in accordance with DIN EN 1465 on the testing machine Zwick / Roell Z150. Based on the results of the research it was found that better results were obtained for the maximum welded joints, but this result was similar to the maximum value of the strength of the adhesive bond.
