Abstract

The invention discloses an anti-collapse support device for welding porous seats on a cylinder wall, which solves the problems that the supports of the holes interfere with each other and the jack cannot effectively support when a plurality of hole seats are welded on the cylinder body. The third hole seat (4) included in the circular cylinder wall (1) is provided with a hole seat welding lower backing plate (6), which is arranged under the first hole seat (2) and the second hole seat (3) The hole seat is welded with the upper backing plate (5), the jack (11) is arranged between the hole seat welding lower backing plate (6) and the hole seat welding upper backing plate (5), and the hole seats on both sides of the jack (11) A left support screw rod (7) and a right support screw rod (9) are respectively arranged on the welding lower backing plate (6), and the nuts on the two support screw rods are connected together with the lower top surface of the welding upper backing plate (5) of the hole seat. The invention realizes the thermal aging treatment of the supporting device along with the product, and improves the welding quality.

Description

technical field [0001] The invention relates to a welding tool, in particular to an inner tube welding support tool used when welding a plurality of hole seats on the tube wall of a thin-walled tube. Background technique [0002] On the thin-walled cylinder, multiple hole seats need to be welded according to the process requirements. Due to the thin wall thickness of the cylinder, there are different problems of stress release during the welding process and after welding. After the hole seat is welded, the weld seam will collapse. . The traditional process is to use a jack to support the hole seat in the cylinder after assembling the hole seat on the thin wall of the cylinder. After confirming that the hole seat is assembled correctly, the shell is pre-welded and welded. Since the hydraulic jack cannot be used upside down or installed horizontally, a jack is required for each hole seat to be welded. When there are multiple hole seats to be welded on the cylinder, there will...
