Automated Gas Welding Systems
Metal inert gas (MIG) or gas metal arc welding (GMAW) is one of the most popular welding processes for all applications, commercial, industrial and even for hobbyists. Automated welding systems for robotic MIG welding take the process to another level, offering companies the potential to significantly improve productivity and profitability.
Furthermore, robotic MIG welding systems are considerably easier and simpler to use than many fabricators think.
Automated Welding Systems for MIG Welding
The MIG welding process is faster than other arc welding processes, and the use of robots speeds up the process even more, further increasing efficiency. Additionally, MIG welding robots (or robotic welding cells) can weld in just about all positions, adding flexibility to the welding process. Because they can be put on gantries and tracks, they can also weld very large long parts, up to 10 ft wide and 50 ft long.
Another advantage is that robots don’t have to be dedicated to single tasks like making a single part of a weldment. They can be programed to do multiple tasks, and are able to move from part to part quickly, which makes the process even more efficient.
Whether executed by humans or robots, the MIG welding process has a high deposition rate and produces superior quality weldments. Unlike arc welding processes that utilize a hand-held electrode, the consumable electrode for MIG welding comes on a spool that fits into the machine. This is automatically fed through the welding gun together with a continuous flow of shielding gas, enabling the operator to create smooth, clean welds without slag that needs to be chipped or ground away later.
Robotic MIG welding is considered to be a semi-automatic welding process even though errors that might occur are generally detected and corrected by the robot rather than by human intervention. However, robots are not able to solve welding quality problems and so it is essential that all parts for a weldment are properly designed and the parts correctly made. Welding joints must also be properly prepared before the robot starts work on them otherwise quality problems will be inevitable.
Automated welding system robots are easy to program, and robot operators don’t need the same skills welders need to work. However, even though robots can weld just about anything a human can, sometimes positioning and clamping requirements make the use of a robotic welding cell impractical. For this reason it is important to discuss your needs with experts before you commit to a new system.
