Welding automation technology

Thread Content

Over the past few decades, welding technology has developed at a rapid pace, just like other scientific and technological fields. The emergence of welding methods such as lasers, electron beams, plasma, and gas shielded welding, along with the continuous development and improvement of high-quality, high-performance welding materials, has made it possible to weld almost all engineering materials. Moreover, welding automation is developing rapidly. Automated production methods have replaced manual welding in many industrial sectors. Among various welding techniques and systems, the mechanization and automation of welding processes, as well as flexible manufacturing systems for welding, characterized by the integrated use of electronic, information, and computer technologies, represent important features of welding technology in the information age. Achieving automation, flexibility, and intelligence in the manufacturing of welded products has become an inevitable trend. The use of robotic welding has become a major indicator of the modernization of welding automation technology. Welding robots are attracting increasing attention due to their versatility and reliable performance. The use of robotics in welding production can increase productivity, improve working conditions, ensure stable and consistent welding quality, and enable the automation of welding for small-batch products. The welding flexible manufacturing system (unit) is a typical representative of welding technology in the information age. Generally, it consists of welding robots, advanced welding power sources, offline programming CAD systems, and tooling machinery systems. Welding robots possess more advanced capabilities than other robots; in addition to being able to move around and carry objects, they can also automatically track the trajectory of the welding arc, thereby preventing interference from the arc and dust. In welding mechanization and automation systems, the welding power supplies used all possess excellent dynamic characteristics. Most of these welding equipment are developed using advanced electronic components and electronic technologies, such as inverter-type thyristor welding power supplies and IGBT inverter-type welding power supplies. Most welding methods used for Ye are those with high welding quality and high productivity, such as automatic or semi-automatic CO2 welding, MIG/MAG welding, TIG welding, and submerged arc welding. The offline programming CAD system enables the programming of welding processes to be carried out autonomously, and allows for simulation tests of most actions in the entire welding process without relying on the entire flexible system. Welding is a highly variable and complex process, and other variables such as thermal deformation also occur during welding. As a result, many welding engineering software programs have been developed with the aim of predicting such variable conditions, in order to analyze and calculate the numerous variables involved in the welding process. Such software is widely used in offline programming CAD systems. Tooling and mechanical systems are primarily used to carry out functions such as the assembly, positioning, and welding of welded products; they include devices like welding positioners, wheel brackets for welding manipulators, turntables, and flipping machines. They also encompass auxiliary tooling equipment that facilitates the automatic transportation of welded products.
