The hydroforming process represents an alternative production method when complex geometry components are re- quired. Considering the cost per unit as a critical value, hydroforming shows up as a competitive production method. ＇In this work a case study is presented where the initial part, two tubes with different thicknesses and joined with a butt - weld, is hydro- formed. Simulation analyses are presented using the Finite Element Method. A particular focus will be carried out on the charac- terization of the Heat Affected Zone （ HAZ）, namely geometry and mechanical properties.
