Influence study of negative temperatures on stressed-strained state of glue-welded joints

The study results for the assessment of the influence of negative temperatures on the change in the stressed-strained state of welded and glue-welded joints made using various types of adhesive materials are presented. An epoxy compound and melt adhesive based on ethylene copolymer with vinyl acetate were used as adhesive materials. Using tomography, it was found that a glue-welded joint made on a melt glue had the best characteristics, both at positive and negative temperatures.
