Abstract
Distortion phenomena occurs in large structures as bridges, ships compromising its integrity when under stress in its lifespan. Although with the thickness increases the distortions start to be more insignificant, thinner structures are more likely to deform during welding because of a lack of rigidity. Other important parameters when studying distortional behaviour is the heat input and the joint project, the first one has an opposite effect to the thickness and the second one influences on the thermal behaviour of the process. The aim of this study is to understand the distortional behaviour of a naval steel when the structure is assembled using gas metal arc welding in T joints with heat input variation, so for this purpose measurements of heat in the plates will be taken using thermocouple and the distortional data will be obtained by means of measuring the deviation of linearity on the plates as welded. Is expected that with heat input increases distortion increases.
