Zusammenfassung:	The utility model provides an optimized structure for welding a boiler shell. The optimized structure comprises a cylindrical body. The cylindrical body is made by rolling up a steel plate. Two inclined surfaces are formed on both ends of the joint of the steel plate and a V-shaped groove is formed by the two inclined surfaces. According to this arrangement, welding can be done in the V-shaped groove to enable welding flux to flow into the V-shaped groove completely. Accordingly, defects as pseudo soldering and sealing off can be avoided, so that the safety can be improved by using the boiler.
