Abstract

PURPOSE:To obtain penetration beads which are free from weld defects such as undercuts and blowholes by incorporating specific components into the solid fluxes of a backing strip for one-side welding and specifying the dimensional difference of the adjacent tile-shaped solid fluxes determined by the equation. CONSTITUTION:The backing strip for one-side welding is formed by arraying plural pieces of the tile-shaped solid fluxes 2 continuously and sticking the same to a flexible tape 1 having an adhesive part to steel products. The solid fluxes contain 45-65wt.% SiO2, 30-45wt.% Al2O3 and 0.8-6.5wt.% Li2O and the dimensional difference of the adjacent tile-shaped solid fluxes determined by the equation is confined within 15%. The penetration beads which are free from the weld defects such as undercuts and blowholes and has a uniform and bead shape are thereby obtd.
