Abstract

In this study, definitions of Weld Penetration (WP), Depth of Fusion (DOF) and Throat Thickness (TT) in fillet welds according to related standards are reviewed. WP, DOF and TT are crucial dimensions for welded joints since these values determine the weld quality. In AWS A3.0, ISO2553, Eurocode EN 1993-1-8 and DIN EN ISO 17659, these terms are defined, explained and shown in figures. Each standard makes its own definition related with WP, DOF and TT. Moreover, when looking at these standards, it is seen that definitions are always made in terms of unit of length. In some studies, assessment of fusion or penetration (FOP) rate on fillet welds is performed as the ratio of the maximum FOP depth to the material thickness. Depth assessment taking into consideration unit of length is not ideal for accurate evaluation of FOP rates especially on fillet welds. Method taking into consideration unit of area will be more suitable as it allows accurate assessment of FOP rates in welded joints. In this review, it is also suggested that the evaluation of FOP rate on fillet welds should be determined in terms of unit of area rather than length.
角焊缝熔深、熔深和喉道厚度定义的回顾
本文综述了相关标准对角焊缝熔深(WP)、熔深(DOF)和喉道厚度(TT)的定义。WP, DOF和TT是焊接接头的关键尺寸,因为这些值决定了焊接质量。在AWS A3.0、ISO2553、欧洲规范EN 1993-1-8和DIN EN ISO 17659中,这些术语用图表进行了定义、解释和显示。每个标准对WP、DOF和TT都有自己的定义。此外,当查看这些标准时,可以看到定义总是根据长度单位进行的。在一些研究中,用最大熔透深度与材料厚度之比来评估角焊缝的熔透率。考虑长度单位的深度评估对于准确评估FOP率并不理想,尤其是在角焊缝上。考虑面积单位的方法更合适,因为它可以准确地评估焊接接头的FOP率。在这篇综述中,还建议评价角焊缝的FOP率应以单位面积而不是长度来确定。
