The invention discloses a welding method of an inner wall plate of a diversion pipe and belongs to the technical field of shipbuilding. The welding method includes that: a, adjusting the inclination of two workpiece supporting plates respectively to make it to correspond to the inclination dimensions of a bending section and an inclined section; b, placing the bending section and the inclined section on the two workpiece supporting plates correspondingly, enabling welding ports of the bending section and the inclined section to be opposite to each other and clamping the welding ports; c, placing a slab section on a workpiece supporting base and clamping the slab section; d, adjusting the height of the workpiece supporting base, enabling welding ports of the slab section, the bending section and the inclined section to be in butt joint and fixing the slab section in a spot fixed welding mode; e, finishing welding of the whole inner wall plate of the diversion pipe in a carbon dioxide arc welding or manual arc welding mode. The welding method can solve the problems of the existing welding of the inner wall plate of the diversion pipe of shifting easiness, high construction cost due to the large number of tools as well as management inconvenience during welding.
Description
technical field [0001] The invention relates to the technical field of shipbuilding, in particular to a welding method for an inner wall plate of a draft tube. Background technique [0002] The diversion pipe for ships is a force-increasing component installed in the radial direction of the propeller of the propulsion part of the ship. The existing diversion pipe for ships includes an outer wall plate and an inner wall plate, such as figure 1 The shown inner wall plate 8 of the draft tube includes a curved section 83 , a flat section 82 and an inclined section 81 ; the inner wall plate of the draft tube is welded by three plates of different shapes. Since the inner wall plate of the diversion tube is welded by three irregular plates, there are: 1. It is difficult to locate, and it is easy to shift during welding. Deviations occur, and the manufacturing accuracy of the product does not meet the requirements; 2. When welding the inner wall panels of the diversion tube with di...
