Abstract
A method for welding of steel pipe to a pressure vessel comprising the steps of cutting an opening in the wall of the pressure vessel, joining a connection member which consists of a thickened rim or lenticularly shaped disc, aligning the disc with a bore at a right angle to a tangential plane of the outer surface of the connection member, and welding in two specific areas whereby said first weld at the rim of said forged disc to the wall of said pressure vessel has greater strength against notch breaking at the thicker portion and the second welding at the opening of the wall of said pressure vessel provides a smooth transition.
