<p>A method of electric-arc welding of reservoirs for agressive mediums comprises preparation of the edges to be joined by weld, sealing the gap with the use of a consumable electrode to form the weld seam and tempering the latter. When forming the weld seam the gap between the edges (1) to be joined is filled successively with different metals through its thickness, so that one part (5) of the weld seam is formed with a metal the coefficient of linear expansion of which is lesser than that of a metal used for forming the remaining part (6) of the weld seam. </p> |
