| Abstract: | The fracture toughness test for the welded joint (welding seam and heat affected zone) of CF-62 steel was carried out. It was shown that the fracture toughness (J ) of the welded joint of CF-62 steel was well fitted for log-normal distribution by combination of the goodness-of-fit test and probability paper methods. |
