A nuclear reactor pressure vessel is formed of shells 2 constructed of sheet steel rings 3 formed from sheet 4. Each sheet 4 is laid round the cylinder 1 with elastic deformation. The weld 5 joins the end edges of each strip together and to the metal surface beneath. Similarly, the strips are joined at the circumferential welds 6. All welded joints are staggered. The rings 3 are pre-heated electrically before securing in place. The sheets 4 may be cut obliquely at the ends to form the inclined joints 7.
