Peening as a stress relieving method for welded joints
Description
The efficacy of the process of stress relieving by hammer-peening, in heavy plates of low carbon steel is analysed. The effects of peening in the mechanical properties of welded metal deposited by shield metal arc welding, using the electrodes E-6010, E-7018 and E-8018C-2, and the weld metal deposited by submerged arc welding, using the filler metals ENil and EA3, are also analysed. X-ray diffraction was used in order to verify the efficacy of peening as a stress-relieving process. The obtained results and the literature reviewed show that, peening is effective in stress relieving. (author)
Abstract (Portuguese)
Analisa-se a eficacia do processo de alivio de tensoes por martelamento em soldas de chapas grossas de aco baixo carbono. Analisam-se tambem os efeitos do martelamento nas propriedades mecanicas do metais de solda depositados pelos eletrodos de classificacao AWS E-6010 E-7018 e E-8018C-2 (Soldas ao arco eletrico manual) e pelos arames ENil e EA3 (soldas a arco submerso). Para verificar a eficacia do martelamento como processo de alivio de tensoes, utilizou-se o metodo de medida de tensoes residuais por difracao de raios-X. Dos resultados obtidos e da literatura consultada, conclui-se que o processo e eficaz em aliviar tensoes. (autor)Files
