in the present study, the corrosion behavior of aisi 347 austenitic stainless steel to astm a335 low alloysteel dissimilar joint was investigated. for this purpose, two filler metals, er309l and ernicr-3, were selected to be used during the gas tungsten arc welding process. to investigate the corrosion behavior of the joints after welding, the specimens were tested in 3.5% sodium chloride solut...
In order to study MIG welding process of aluminum alloy with longitudinal magnetic field, thermal efficiency with longitudinal magnetic field was analyzed, as well as softening behavior of heat-affected zone (HAZ) and base metal were investigated. The results showed that under the action of longitudinal magnetic field, welding current decreased and resultingly total heat input reduced as the ex...
The effect of heat input of submerged arc welding process on the corrosion bahavior of weld metal of API X42 gas pipeline steel weld joint was investigated. For this purpose, 6 annealed sheets of 15mm thickness were prepared from the X42 microalloyed steel. Submerged arc welding process with varying heat input of 37.8, 18.9 and 12.6 kJ/mm was used for joint welding. Then potentiodynamic polariz...
