An auto component company using MIG welding in manufacturing. MIG welding uses shielding gas during welding to avoid oxidation at weld joints. The company use Argon + Co2 gas mixture as shielding gas. Shielding gas is brought to the consumption point ( robotic welding stations ).We need to monitor the consumption of this gas at each station with a computer data logging solution. There are more than 50 robotic welding stations. For analysis it has to be linked with the welding length.
