Abstract

PURPOSE: To easily carry out welding having no defect without producing shallow part of peneration, by extending starting and teminal end of weld bead of web material and crossing the weld bead in each direction, at the time of carrying out T joint welding of each material of web and flange.
CONSTITUTION: Tip end parts of starting and terminal of the weld bead 13, 14 in longish direction of the web material 1 and the weld bead 15, 19 in board thickness direction, are extended and each bead is crossed and then, the above both parts are separated from weld zone. Hereby, penetration of the weld metal 16, 17 in longish direction and the weld metal 18 in board thickness direction, is carried out sufficiently at the weld zone of the material 1. Also, welding is made easy by nedding no turning operation of the weld bead and automation of welding is made possible.
