At present, with the development of the economy and the accelerated pace of people's lives, people's requirements for welding efficiency and quality are getting higher and higher. The realization of mechanization and automation of the welding process has been regarded as the strategic goal of the welding industry, and as a new industry, on-site pipeline automatic welding is also in the stage of rapid development.
In recent years, in the international welding industry, on-site pipeline welding has been continuously improved with the continuous development of the economy, but welding automation is still in the initial stage of the emerging industry.
From the current point of view, on-site automatic welding of pipelines is still mainly manual welding, so it still faces the following problems: 1. The welding task is heavy, the construction process is slow, and the welding strength is high; 2. The welding seam quality is unstable and the risk of rework is high, with low efficiency; 3. The skill requirements of welders is high; and it is difficult to recruit welders; the high-level welders are few and the wages are expensive; 4. The on-site construction situation is complicated, the construction of personnel is difficult, and the working environment of the welders is poor, which increases the difficulty of work; 5 There are many factors affecting welding, the welding forming is poor, and the welding speed is slow.
All-position pipeline automatic welding machine (also known as pipeline automatic welding machine, orbital automatic welding equipment, orbital automatic welding machine, on-site pipeline welding equipment, automatic welding head, pipeline automatic single torch external automatic welding machine, magnetic automatic pipeline welding machine, etc.) is a high-efficiency automatic pipeline welding equipment developed to meet the on-site pipeline welding requirements under various working conditions. Take Tianjin Yixin pipeline all-position automatic welding equipment as an example. The automatic welding machine consists of a welding head (including an integrated wire feeding device), a wireless remote control, a customized welding power source, and a welding track, which is small and light, suitable for welding pipes and pipelines with DN273mm or more and wall thickness greater than 5mm. During the welding process, the pipe is fixed, and the welding head crawls along the track to realize automatic 5g welding of the pipeline at all positions; welding data can be edited and entered in real-time, storage and recall, automatic welding and manual welding can be switched freely, with a higher degree of automation. This on-site pipeline welding machine adopts a portable design and is suitable for field construction. It adopts integrated storage and homing system and is equipped with a universal wheel at the bottom to facilitate the transfer between projects. The equipment can meet the GMAW/FCAW-GS welding process under various working conditions, and the welding efficiency is significantly improved (about 3-4 times that of traditional handle welding). The on-site pipeline welding seam is beautiful, and the welding seam quality can meet various flaw detection requirements such as AUT/MT/RT.
