Abstract:
Provided is a pressure container in which a lid member is circumferentially welded to an end part of a jointed pipe, wherein welding defects are not prone to occur in the circumferentially welded portion of the lid part and a joint portion of the pipe, and an increase in thermal strain due to circumferential welding can be suppressed. A pressure container in which a casing (20) is provided with a pipe (21) having a joint, and a top lid member (22) for blocking a pipe opening, the top lid member being circumferentially welded to a top end part of the pipe. In a circumferentially welded part (100) of the pipe and the lid member, the heat input per unit length during welding in a first part (110) passing through a pipe joint portion (WA) is greater than the average heat input per unit length in a second part (120) exclusive of the first part.
