Resumo
The aim of the experimental arrangement is the measurement of the weld pool
temperature during the application of the conventional arc GTA-welding on autogenous
thin plates of UNS S32304 duplex stainless steel. Grade UNS S32304 was developed
for the most severe applications including off-shore. The stationary arc welding was
applied with a DC current for two minutes using pure argon as shielding gas in center
of the duplex stainless steel disc. For the temperature into the weld pool were used a
S-type (Pt-Rh) and K-type (Ni-Cr) thermocouples connected close to weld pool. The
temperatures were measured in top and botton sides of the plates. It was observed an
overheating temperature into the weld pool on the top side and as expected the fusion
point was verified in corresponding at the bottom side. The microstructure was
characterized and an increase of ferrite phase in solidified zone and heat affected zone
was observed. The hardness mapping provided information about mechanical
properties behaviour. A numerical analysis of temperature distributions were used to
simulate welding cycles associated to microstructure evolution.
