THROUGH-DIAPHRAGM WELDED JOINT STRUCTURE
PROBLEM TO BE SOLVED: To provide a through-diaphragm welded joint structure in which the occurrence of cracks can be delayed even employing a simpler welded joint.SOLUTION: A through-diaphragm welded joint structure (10) is provided which includes a joint formed by welding square tubes (11, 12) and a diaphragm (20) to each other. The through-diaphragm welded joint structure (10) has a main welded part (23) being a welded part between end faces of the square tubes and a plate face of the diaphragm, and a backing strip (21) which is arranged at an inlet corner between the square tubes and the plate face of the diaphragm. The backing strip and the square tubes include fillet-welded parts (22) which are intermittently fillet-welded including four corners of the square tubes. The through-diaphragm welded joint structure (10) is formed in such a way that a distance from the plate face of the diaphragm up to toe-of-weld parts of the fillet-welded parts becomes longer than a distance from the plate face of the diaphragm up to a toe-of-weld part of the main welded part.
【課題】より簡易な溶接継手であっても亀裂発生を遅らせることができる通しダイヤフラム溶接継手構造体を提供する。【解決手段】角形鋼管（１１、１２）とダイヤフラム（２０）とを溶接した継手を含む通しダイヤフラム溶接継手構造体（１０）であって、角形鋼管の端面とダイヤフラムの板面との溶接部である主溶接部（２３）と、角形鋼管とダイヤフラムの板面との入隅部に配置された裏当て金（２１）と、を有し、裏当て金と角形鋼管とは、該角形鋼管の四隅を含んで断続的にで隅肉溶接された隅肉溶接部（２２）を備え、ダイアフラムの板面から隅肉溶接部の止端部までの距離が、ダイアフラムの板面から主溶接部の止端部までの距離より大きくなるように形成されている。【選択図】図２
