Description

The aim of the research is to enhance the mechanical properties of 9%Ni steel LNG tank welded joints and significantly impact toughness. The experiment started by using 10- and 14-mm plates of 9%Ni steel .welding was done using E NiCrFe4 with a diameter of 3.2 mm for two groups of specimens ( 3 specimens of 10 mmm and 3 specimen of 14mm). In the same way, using E NiCrMo3 . the welding is done by using two WPS one for each electrode. all welding is done in a vertical uphill position. measuring the ampere and volt using a clamp ampere. Travel speed is measured by a stopwatch for time and distance by a ruler. All specimens were inspected using LPT and gamma-ray. the mechanical tests were micro Vickers hardness and impact toughness. Plus the macrograph and microstructure by using an optical microscope.
