STRION LASER’s Handheld Laser Welding | Traditional Argon Arc Welding | |
| Welding effect | Beautiful welded joints | Post-processing grinding or polishing is needed for welded joints |
| Heterogeneous metal splicing | Yes | No |
| Workpiece deformation | Small | Large |
| Welding efficiency | It is 6-10 times the efficiency of argon arc welding | Energy is not concentrated and efficiency is wasted |
| Cost of use | Unskilled workers can operate, savign labor costs | High grade level welders required |
| Physical hazards | Low radiation, protective spectacles can filter out strong light | Great harm to welders and high incidence rate of occupational diseases |
| Environmental Pollution | Green and environmentally friendly | A large amount of smoke and dust pollution |


TIG welding is time-consuming and requires skilled operators, generating high heat that can distort thin materials, reduce cosmetic quality, and limit welding of copper or metals with varying thicknesses. STRION laser welding machines overcome these issues with precision and efficiency.


Compared with MIG or TIG, STRION laser welding machines use independent “small core diameter” laser welding technology with dual-circuit refrigerant cooling and integrated design, delivering higher efficiency, deeper penetration, energy savings, and easy operation.


MIG welding requires consumable wire, material pre-cleaning, and beveled joints in thick metals to allow for complete penetration. Movement and working angles are limited, and vertical positions are challenging.
