Welding Productivity Challenges
Arc-on time is the share of a shift during which a welding machine is actually laying weld. In most welding shops it is only 30–40% — the rest goes to setup, changeover, fixture and fit-up work, material handling, and plain waiting.
Almost nobody measures it, because the only honest way to measure it is to capture the arc signal off the machine. A supervisor walking the floor sees a busy shop. The welder’s own estimate is generous, and the production count tells you what was welded, not how long the machine stood idle to weld it. An industrial IoT gateway reads that signal directly. See also fabrication shop productivity.
Welding is a critical operation in fabrication industries, yet productivity in welding shops is rarely measured accurately.
Common problems include:
- Idle welding stations
- Unmonitored arc time
- Excessive shielding gas consumption
- Uneven workload distribution
Measuring Arc-On Time and Machine Utilization
A key metric for welding productivity is Arc-On Time.
This metric indicates how much time the welding arc is actively producing welds.
Monitoring Shielding Gas Consumption
Shielding gases such as Argon, CO2, and Argon-CO2 mixtures represent a significant operational cost.
IoT-enabled gas monitoring systems measure:
- Gas flow rate
- Total gas consumption
- Leakage detection
Machine Signal Intelligence in Welding Operations
Signals used for monitoring include:
- Arc start signals
- Current flow signals
- Machine power status
- Production counters
These signals provide insight into actual welding activity.
