WELD JOINT FOR THIN SHEET MEMBER, METHOD FOR MANUFACTURING CAN PROVIDED WITH SAID WELD JOINT, AND PIPE-LAYING METHOD FOR PIPE PROVIDED WITH SAID WELD JOINT

摘要

An L-shaped end portion (1A) having a bending angle (¸1) that is a right angle is provided at one end of a first thin plate member (1), a Z-shaped end portion (2A) having an eave portion (2B) and having a bending angle (¸2, ¸3) that is a right angle is provided at a second thin plate member (2), and engagement is achieved such that a contact surface (1C) of the L-shaped end portion (1A) and a contact surface (2C) of the Z-shaped end portion (2A) are in close contact with each other and a lower surface (2D) of the eave portion (2B) opposes a top portion (1B) of the L-shaped end portion (1A) with a predetermined gap (G) provided therebetween, whereby a weld joint (20) is formed.
