Problems solved by technology

[0003] In the process of ship construction, when the welded pipe joints and pipes are butt welded, two people are often required to cooperate to fix the pipe joints and pipes by spot welding. Deviation, unstable welding and other conditions affect the welding quality, so a kind of equipment and method for butt welding of pipe joints and pipes is proposed to solve the above technical problems

Embodiment 1

[0027] Embodiment one: refer to Figure 1-6 , the present invention relates to a pipe joint and pipe butt welding equipment, the equipment includes two support bases 1, the top of the support base 1 is respectively welded with a first support rod 2 and a second support rod 6, the first support rod 2 The end far away from the support base 1 is welded with a fixed pipe joint hoop 3, and the end of the second support rod 6 away from the support base 1 is welded with a fixed pipe hoop 7 to keep the centerline of the fixed pipe joint hoop 3 and the fixed pipe hoop 7 The installation directions of the center lines of the two are consistent, and the two center lines are on the same line to ensure concentricity. There are at least two fixed pipe hoops 7, which can be increased in moderation according to conditions such as pipe 10 lengths. The fixed pipe joint hoop 3 and the fixed pipe hoop 7 are equally divided into upper and lower parts, and a hinge 4 is arranged between the upper an...

Embodiment 2

[0029] Embodiment two: refer to Figure 1-6 , on the basis of Embodiment 1, a method for using equipment for butt welding of pipe joints and pipes, the method includes the following steps:

[0030] S1: Place the flat shoulder joint inside the hoop of the fixed pipe joint, and keep the relative height of the fixed pipe hoop that clamps the pipe consistent with the hoop of the fixed pipe joint;

[0031] S2: Fix the flat shoulder joint and the port where the pipe is close to each other by spot welding;

[0032] S3: After loosening the locking bolts, remove the spot-welded pipes and perform complete welding.

[0033]In the specific operation process, the method includes the following use process: placing the flat shoulder joint 9 inside the fixed pipe joint hoop 3, inserting the locking bolt 5 into the nut 8, and then placing the flat shoulder joint 9 in the fixed pipe joint hoop In the card groove inside the hoop 3, the flat shoulder joint 9 can protrude out of the fixed pipe j...

Abstract

The invention discloses equipment for butt welding of a pipe joint and a pipe and a using method, relates to the field of ship building piping system welding, and provides the following scheme aiming at the problems that during butt welding, deviation is possibly generated during centering of the pipe joint and the pipe, welding is unstable and the like. A first supporting rod and a second supporting rod are welded to the top of the supporting base, and a fixing pipe joint hoop is welded to the end, away from the supporting base, of the first supporting rod. According to the butt welding equipment, the pipe joint fixing hoop, the pipe fixing hoop, the supporting rod and other structures are installed, the pipe joint fixing device and the pipe fixing device are arranged, the stability and concentricity of a pipe joint and a pipe during butt welding are improved, the butt spot welding operation can be completed by only one person through the equipment, the labor cost is reduced, and the production efficiency is improved. And the construction difficulty is reduced, and the centering precision and the welding quality during butt welding of the pipe joint and the pipe are improved.

Description

technical field [0001] The invention relates to the field of shipbuilding pipe system welding, in particular to equipment and a method for butt welding pipe joints and pipes. Background technique [0002] Ship welding technology is one of the main key technologies of the shipbuilding industry. At present, the world's major shipbuilding enterprises have generally completed a round of modernization in the mid-1990s. At the same time, a new round of modernization has been launched on this basis. The transformation plan, a large number of new shipbuilding welding processes, highly flexible automated welding production systems and advanced welding robot technology, to ensure that these shipbuilding powers have unique technological advantages in international competition, enter the 21st century, and face new challenges It is extremely realistic and pertinent to carry out comprehensive analysis and research on my country's ship welding technology. At the same time, carbon dioxide gas...
