Laser Welding vs TIG Welding Comparison
How much faster, more efficient and cost-effective can laser welding be compared with traditional TIG welding?
This test from our partners at THEO takes a closer look at the test setup and results, comparing the two processes across working time, filler wire consumption, gas consumption and energy usage.
Detailed Test results
Basic Data
• Welding length: 500 mm
• Base Material: Stainless Steel (AISI 304)
• Thickness: 2.0 mm
• Application: Fillet Weld (T-Joint)
Working Time
| Process | Process Time |
| LASER | 29 seconds |
| TIG | 173 seconds |
Result:
Laser reduces working time by 83.24% compared to TIG, excluding post-processing steps.
Filler Wire Consumption
| Process | Wire length consumption |
| LASER | 348 mm (13.7 in) |
| TIG | 1000 mm (39.4 in) |
Result:
Laser reduces filler wire consumption by 65.2% compared to TIG.
Gas consumption
| Process | Gas Flow rate | Total consumption | Gas Type |
| LASER | 29 seconds | 7.25 litres | N2 |
| TIG | 173 seconds | 34.6 litres | AR |
Result:
Laser reduces gas consumption by 79.04% compared to TIG.
Energy consumption
| Process | Power | Total consumption |
| LASER | 6KW | 0.2175 kWh |
| TIG | 22.8KW | 1.1 kWh
|
Result:
Laser reduces energy consumption by 80.23% compared to TIG.
