摘要： PROBLEM TO BE SOLVED: To provide a method of making a connection part (1) between a hollow member (2) made of steel and a member (3) made of aluminum material capable of achieving frictional joining, shape joining and material joining connection relating to the press fitting. SOLUTION: First, the hollow member (2) is press-fit onto the member (3). Thereafter, a welding layer is brought about according to thermal joining by using a filler metal (19) and the filler metal makes the shape joining and material joining connection between the hollow member (2) and the member (3). The shape joining connection is supported on the press-fitting end part (15), which is preliminarily deformed, of the hollow member (2). Deformation is preferably performed by expanding the press-fitting end part (15) toward a collar (16). COPYRIGHT: (C)2011,JPO&INPIT

摘要： PURPOSE:To improve the high-temperature and corrosion resistance of a stainless steel pipe on the vicinity of a weld zone by forming the weld zone with 'Inconel(R)', and forming a chromized layer on the surface of the stainless steel pipe of the vicinity of the weld zone, when welding a Cr-Mo steel pipe and an austenite stainless steel pipe. CONSTITUTION:When welding each dissimilar metal of a Cr-Mo steel pipe 1 and an austenite compound stainless steel pipe 2, etc., a weld zone 7 is formed by 'Inconel(R)' of an Ni-Cr-Fe compound, the inside and outside surfaces of the stainless steel pipe 2 within a range L of 100-200mm are brought to chrome diffusing and infiltrating treatment, and a chromized layer 6 of 80-120mum is formed. Or between the Cr-Mo steel pipe 1 and the stainless steel pipe 2, a transition piece 8 whose material quality is the same kind as that of the stainless steel pipe 2, and which has the chromized layer 6 on the inside and outside surface is interposed, and weld zones 9, 10 are welded by 'Inconel(R)'. In this way, the high temperature and corrosion resistance of the stainless steel pipe 2 on the vicinity of the weld zone is improved remarkably.

摘要： PURPOSE:To stick an Al pipe material fast to a member made of Fe by fitting a pipe material made of Fe inside of which is made rough to an unweldable pipe material such as Al etc. from outside, and after expanding from inside of the Al pipe or fastening from outside of the Fe pipe material, welding a member made of Fe to the Fe pipe material. CONSTITUTION:The pipe material made of Fe 3 inner face of which is roughened by forming minute unevenness using a cutting tool etc. is fitted to outer peripheral face of the pipe material 1 made of Al from outside. Then, inside expansion is made to press inner face of the pipe material made of Al 1 or the pipe material made of Fe 3 is pressed from outside by outside fastening and the Al pipe material 1 and Fe pipe material 3 are stuck strongly. Then, a supporting member 2 made of Fe of the same quality with the Fe pipe material is welded 5 to the Fe pipe material 3. Thus, the pipe material and supporting member made of unweldable Al and Fe can be stuck strongly.
