Description

Zig apparatus for fixing T-type pipe for chamber type welding head The present invention relates to a jig device for a welding head for maintaining a base material to be welded in a tack-welded state during a welding process using a welding head. More specifically, in welding using a welding head, it is necessary to weld while moving the welding rod while maintaining two base materials to be welded in a butt-together state. The present invention relates to a jig device for fixing a T-shaped pipe for fixing and maintaining a vertical base material and a horizontal base material in a tack-welded state during welding, specifically for welding a T-shaped pipe. Welding is a method of joining metal materials and is applied in various fields. A prime example is the shipbuilding industry, where parts are manufactured simultaneously and then welded together to form a ship in order to reduce delivery times; welding is used to join the separately fabricated hulls during this process. Additionally, welding is used to join various types of pipes. For instance, the manufacturing of semiconductors and display panels utilizes a wide range of chemicals, and pipes of various shapes must be installed to transport them to appropriate equipment; welding is used to join these pipes. Among these, the T-shaped pipe is a form in which horizontal and vertical pipes are connected, and it is called a T-shaped pipe because the joint resembles the shape of a T. Since the areas to be welded are the hole formed in the horizontal pipe and the end of the vertical pipe, the horizontal and vertical pipes must be fixed in the correct positions before welding is performed to ensure accurate welding. Welding methods are broadly divided into consumable and non-consumable welding methods, distinguished by whether the electrode is consumed. Representative consumable welding methods include shielded metal arc welding, gas metal arc welding, and submerged arc welding, while representative non-consumable welding methods include TIG welding. TIG welding is a method called gas tungsten arc welding that supplies an inert gas (such as argon or neon) that does not react with metal even at high temperatures to protect the arc environment from the intrusion of oxygen or hydrogen, and uses tungsten as a non-consumable electrode. In particular, welding using a welding head employs an automated welding method in which the tungsten electrode rotates over the welding area. In other words, automated gas tungsten arc welding creates a passage to supply inert gas inside a welding head where a tungsten electrode rotates, and welds the abutting base material as the tungsten electrode rotates; it is typically used for welding straight pipes. However, this automated gas tungsten arc welding head has a problem in that it cannot be used for L-shaped or T-shaped pipes because it does not hold the two base materials in a tack-welded state, as it fixes the straight pipe from both sides and welds by rotating the tungsten electrode around the base material. A pipe welding device is disclosed in Public Patent No. 10-2022-0139542 for welding various pipes. In No. 542, a pipe welding device (100) is provided with a jig member (131, 132) for fixing a vertical pipe (20), and a pipe welding device (100) is positioned above a horizontal pipe (10) via a support member (140) to weld the connection part between the horizontal pipe (10) and the vertical pipe (20). The pipe welding device of No. 542 has a problem in that the welding device (100), which is fixed by the jig member (131, 132) above the horizontal pipe (10) and positioned via the support member (140), causes the welding device (100) to shake left and right when the length of the vertical pipe (20) is long, making it difficult or impossible to perform accurate welding at the connection part. In addition, since the horizontal pipe is not fixed by a jig, there is a problem that a separate configuration is required to fix the horizontal pipe to the welding device (100).
