Welded structure and work vehicle
A welded structure (19) is provided with: a first member (11) formed from a steel plate or cast steel; a second member (12) disposed adjacent to the first member (11) with a space (S) therebetween, the second member (12) being formed of a steel plate or cast steel; a first welded section (21) that fills the space (S) and joins the first member (11) and the second member (12); and a backing material (31) that is disposed in contact with the first welded section (21) so as to close the first opening of the space (S), includes a transformation region (31F) having a martensitic structure in a region in contact with the first welded section (21), and is made of steel. The volume per unit mass of the steel constituting the backing material (31) at room temperature is larger than the MS point.
焊接结构物(19)具有：第一部件(11)，其由钢板或铸钢形成；第二部件(12)，其与第一部件(11)隔着空间(S)邻接配置，且由钢板或铸钢形成；第一焊接部(21)，其填充空间(S)，接合第一部件(11)与第二部件(12)；背衬材料(31)，其以将空间(S)的第一开口部闭合的方式与第一焊接部(21)接触配置，在与第一焊接部(21)接触的区域中包含具有马氏体组织的相变区域(31F)，且由钢构成。构成背衬材料(31)的钢在室温下单位质量的体积比MS点大。
