With the continuous development of welding technology, various welding processes have begun to develop, among which laser welding and CO2 welding (carbon dioxide gas shielded welding) are widely used in various fields, but users often cannot distinguish the characteristics between the two, Let us introduce the difference between laser welding and CO2 welding:
| Item | Laser welding machine | CO2 welding robot |
| Welding material | stainless steel, carbon steel, aluminum | low carbon steel, iron |
| Welding method | non-contact welding | contact welding |
| Welding thickness | 0.5-4mm | 0.5-20mm |
| welding environment | Can work in a vacuum environment | Must work in a closed environment |
| Consumable parts | Lenses, nozzles, etc. | Conductive nozzle, protective nozzle |
| Impact on surrounding components | Small | Big |
| Crack resistance | Poor when welding thick workpieces | Good |
| Application Scenario | Kitchen and bathroom industry (including water pipe joints, stainless steel tee pipes, stainless steel cabinets), automotive industry (including body parts, engine cylinders, hydraulic rods, electric vehicle battery packs and other parts), medical industry (stainless steel support pipes, sealed boxes, etc.) and precision Component | Low carbon steel welding (including furniture, scaffolding, shelves, etc.), welding of various large steel structure projects |
