To provide a weld structure of a work machine having a high resistance against impact load while mitigating stress at a welding point.SOLUTION: In a structure in which an edge part of a plate member 22 corresponding to a second member is abut-welded (weld bead 22d) with a beam member 20 corresponding to a first member, and a notched concave part G is formed in the second member so as to leave an end of the edge part in a projected piece shape, a reinforcement plate 24 is provided which is attached and fixed on the second member along the concave part G.SELECTED DRAWING: Figure 2B
【課題】溶接箇所の応力を緩和しつつ、衝撃荷重にも強い構造を提供する。【解決手段】第1部材に相当する梁材20に第2部材に相当する板材22の縁部が突き合わせ溶接(溶接ビード22d)され、第2部材には縁部の一端を突片状に残すようにして切り欠く凹部Gが形成される構造において、凹部Gに沿って第2部材に取付固定される補強板24を備えることを特徴とする。【選択図】図2B
