Abstract

resumo patente de invenção: "estrutura soldada". a presente invenção refere-se a uma estrutura soldada com uma junta de solda de filete na qual a superfície final de um membro de união é colocada de topo contra a face frontal de um membro unido tendo uma espessura de chapa de 50 mm ou mais, o membro de união e o membro unido são unidos por soldagem de filete, e pelo menos um entre o comprimento da perna de solda e a largura da soldagem é 16 mm ou menos. a estrutura soldada inclui uma porção não soldada em uma face de fronteira entre a face final do membro de união e a face frontal do membro unido, a porção não soldada sendo 95% ou mais da espessura da chapa tw do membro de união em uma seção transversal da junta. a soldagem de filete é ajustada de forma que para um metal de solda de filete, a temperatura de transição de aparência da fratura vtrs (°c) do metal da solda de filete e a espessura da chapa tf do membro unido satisfazem a relação vtrs ? ?1,5 tf + 70, e/ou a energia absorvida ve?20 (j) a ?20°c e a espessura da chapa tf do membro unido satisfazem a relação ve?20 (j) ? 2,75 tf (mm) ? 105. como resultado, a propagação de uma fratura frágil iniciada no membro unido tendo uma espessura de chapa de 50 mm ou mais e tendo uma junta de solda de topo pode ser interrompida em uma porção de metal de solda de filete.patent summary: "welded structure". The present invention relates to a welded structure with a fillet weld joint in which the final surface of a joint member is placed top against the front face of a joined member having a plate thickness of 50 mm or more. the joining member and the joining member are joined by fillet welding, and at least one between the length of the welding leg and the welding width is 16 mm or less. the welded structure includes a non-welded portion on a boundary face between the end face of the joint member and the front face of the joined member, the non-welded portion being 95% or more of the thickness of plate tw of the joint member in one section. cross section of the joint. The fillet weld is adjusted so that for a fillet weld metal, the appearance transition temperature of the fillet weld metal fracture vtrs (° C) and the thickness of the joined member plate tf satisfy the vtrs? ? 1.5 tf + 70, and / or the absorbed energy ve? 20 (j) at? 20Â ° c and the thickness of the joined member plate tf satisfy the ratio ve? 20 (j)? 2.75 tf (mm)? 105. As a result, propagation of a fragile fracture initiated at the joined member having a sheet thickness of 50 mm or more and having a butt weld joint may be interrupted in a fillet weld metal portion.
