Determination of the causes of low service life of the air fan impeller made of high-strength steel
Source abstract
Abstract
Abstract The article presents the results of tests performed to determine the cause of damage to a fan impeller. The damage to the rotor caused, apart from the damage of the device itself, also significant damage to a fan room. The tests included the chemical composition of steel, hardness measurements and microstructure evaluation to determine a grade of steel used for the rotor elements. The tests performed revealed the use of S690Q steel. Visual and metallographic examinations of the damaged areas revealed an improperly conducted welding process and the occurrence of welding imperfections such as cracks, incomplete fusion and gas pores. The analyzed failure case presents the consequences of failure to comply with the welding technological regimes for high-strength steels joining.
