摘要： A method of welding a deck plate and a closed section rib both constituting a steel plate deck, comprising: working a root portion of the closed section rib to have a flat surface in parallel with a surface of the deck plate; and welding the deck plate and the closed section rib while making the flat surface of the closed section rib to be in contact with the surface of the deck plate.

摘要： A pair of thick steel plates are set up side by side such that an I groove with a narrow gap is formed between the facing edges of the plates, and a welding wire projecting from a welding torch of an arc welding unit with a constant voltage characteristic is inserted into the I groove obliquely from above with respect to the thickness direction of the plates. The welding torch is moved vertically while the distal end of the welding wire is caused to reciprocate inside the I groove in the thickness direction. At this time, the wire feed rate Vf is varied and also the extension L of the welding wire is increased or decreased so as to keep welding current Iw at a target value. Further, the wire feed rate Vf is subjected to incremental/decremental correction according to the moving direction of the torch.
