Purpose: The aim of the article is to check whether there are indications that light waves can be used to monitor fuel quality. Design/methodology/approach: Tests of deposits released in fuels during long-term storage were carried out. The research involved observing with the unaided eye illuminated samples of fuels stored in glass vials. The research was qualitative in nature. Samples of diesel oil,...
Purpose: Checking the quality of a joint made with a newly developed method. Design/methodology/approach: A new welding method has been developed in order to obtain a high-quality joint. The properties of the joint were checked by NDT (Non Destructive test) tests and the strength and fatigue strength were tested. Findings: Now, adding to the shielding gas mixture can improve the quality and properties...
Purpose: The aim of the article is to check the quality of the road and classify the selected road on a four-level scale. Design/methodology/approach: The paper outlines the impact of comprehensive road surface quality management on the safety of vehicles and road users. The basic types of road damage were presented, as well as preliminary diagnostics of a randomly selected national road was carried...
Purpose: The novelty and the aim of the article is to check the possibility of welding high 9 strength steels with a mixture containing 7000 ppm of nitrogen. Design/methodology/approach: A new welding material and method have been developed in order to obtain a high-quality joint for automotive industry and for antenna holders and towers. The properties of the joint were checked by NDT (Non Destructive...
