Where laser welding genuinely wins, and where traditional welding still has its place.
| Factor | Laser Welding | Traditional TIG / MIG |
|---|---|---|
| Employment cost | Simple to operate — an ordinary operator is productive in about half an hour. | Skilled welders are hard to recruit and command high wages. |
| Electricity | Runs single phase; consumption is roughly half that of argon welding. | Runs three phase, with high electricity consumption. |
| Consumables | Welds with or without filler wire; no electrodes. | Wire and electrodes are compulsory; torches need regular replacement. |
| Efficiency | 3–8× faster than argon arc welding; over 10 cm/s linear speed. | Slow travel speed and low overall efficiency. |
| Thermal deformation | Concentrated energy, minimal heat-affected zone and distortion. | Large heat input causing warping and deformation. |
| Weld quality | Fine, deep, uniform welds with high strength and little rework. | Rough and irregular; usually needs grinding and polishing. |
| Thin material | Can weld down to 0.05 mm stainless steel. | Struggles badly with very thin sections. |
| Operator safety | Single-wavelength beam, low indirect radiation; protective eyewear required. | Fume, spatter and arc exposure with long-term health risks. |
