<p>A method of fabricating a catalyst converter (5) includes the steps of: obtaining a tubular member (2,20) by rolling up a metallic plate member (1,10) of a rectangular shape having ear portions (11) at four corners thereof such that opposing ones of the ear portions (11) abut against each other, and by effecting butt welding for both ends of the plate member; cutting off projecting portions (12) formed by the ear portions (11) at both ends of a weld of the tubular member (2,20); incorporating a catalyst carrier into the tubular member (2,20) with the projecting portions (12) cut off; effecting drawing for both end portions of the tubular member (20A,20B) with the catalyst carrier (30) incorporated therein; and attaching a pair of flanges, respectively, to the both end portions (20A,20B) of the tubular member (2,20) subjected to drawing. <IMAGE></p> |
