Abstract

The aim of the article was to present issues related to the strength analysis of one of the types of assembly joints - welded joints, taking into account the influence of selected factors: technological - welding method, construction - type of joints and material - type of joined material. The MIG/MAG method (135/136), arc welding (111) and gas welding (311) were used as welding methods. Butt joints and lap joints were made of CuZn37 copper alloy (PN-EN 1652), S235JR unalloyed structural steel (EN 10025) and 1.4301 acid-resistant steel (EN 10088). Welded joints samples were made with appropriate parameters, according to the welding methods. Strength tests of welded joints on MTS BIONIX 370.02 testing machine, in accordance with the PN-EN 1465 standard Based on the obtained test results, it can be seen that the value of stresses and deformations is affected by both the welding method and the type of joint structure, while the type of material to be welded should also be taken into account.
