Welded connections are very popular and applicable joints methods of materials. Welding technology and methods intensely developed in recent times and now its base technology is used in different industrial branches. Pressure vessels, boilers, working machines parts, plane bodies, ship hulls and other structures are made of metal, parts connected together by welding. Many welded connections work under complex stress and strain state also thermally loaded. Engineers apply typical, formulas during the design process of welded connections, some designers attempt also to use Finite Element Method in the modelling and design process of welded connections. It’s well known, welded connections zones enclose a place where materials have different properties than properties of parent materials of connected parts. In this area can cracks initiate and propagate. This paper presents tension test results of welded parts of aluminium alloy sighed as AL 5084. Authors investigated strain energy density and volume energy density dependence in the tension test process of welded specimens. Energy as an universal measure can be applied to investigate complex strength and exploitation problems. Presented results can be used as an introduction for more complicated problems of welded connections where strain energy is a base for mechanical modelling of welded connections.
