Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a weld joint structure, wherein a stable penetration bead is formed and sufficient strength of welding is secured even in the case of welding from one side, wherein welding deformation and the generation of welding defects between an weld initial layer and a root face part are suppressed, and wherein the amount of falling of the joint is restrainable. SOLUTION: In the weld joint structure, a 1st structural member 1, which has a groove with a root face part 4, and a 2nd structural member 2 are arc-welded from one side. The weld joint structure is so composed that protrusions 5, which protrude from the root face part 4 of the 1st structural member 1 toward the side of the 2nd structural member 2 to form a gap g between the root face part 4 and the 2nd structural member 2, are provided at appropriate intervals.
