terve lehe paksuse ulatuses tehtav juure läbikeevitusega põkkõmblus või T-liide, mille tulemusena tekib põkkõmbluse vastaspoolele väike vallik e tugevdus (vrd osaläbikeevitusega õmblus), a groove weld that extends completely through the thickness of components joined; the primary purpose for the use is to transmit the full load-carrying capacity to the structural components they join (compare: partial joint penetration weld)
