Laser welding machines and traditional welding methods are currently two commonly used different welding processes. Laser welding machines use laser beams to weld workpieces, while traditional welding methods rely on arc, gas welding, or friction to achieve welding. There are significant differences between these two methods in terms of process, welding quality, efficiency, and applicability.
1. Different working principles:
Laser welding:
Using a high-energy density laser beam to irradiate the surface of the workpiece, the material is instantly melted and bonded together, achieving welding. Laser welding has the characteristics of non-contact and local heating, with concentrated energy and strong controllability.
Traditional welding:
Including arc welding, resistance welding, gas shielded welding (such as MIG/MAG welding, TIG welding, etc.), these methods mainly melt the workpiece locally through arc, resistance heat or chemical reaction heat, and complete the welding with the help of filling materials or self fusion.
2. Process effect:
Laser welding: With a small heat affected zone, fast welding speed, high accuracy, narrow weld seam and large aspect ratio, it can achieve high-quality welding effects, especially suitable for precision and thin plate welding, and not easily deformed.
Traditional welding: The heat affected zone is relatively large, and the welding speed varies depending on the method. The weld width is large, and the aspect ratio is generally small, which is prone to deformation, hot cracks, and other problems. However, it has good adaptability for welding thicker materials.
3. Application scope:
Laser welding: widely used in precision instruments, automotive manufacturing, aerospace, medical equipment, 3C electronic products and other fields, especially in situations where high-precision and complex structure welding is required, it has obvious advantages.
Traditional welding: widely used in fields such as shipbuilding, bridge construction, steel structures, pressure vessels, and general machinery manufacturing, suitable for large-scale production and extensive welding operations.
4. Cost and Equipment:
Laser welding: The investment cost of the equipment is relatively high, but due to its advantages of high efficiency, precision, and energy saving, the unit cost may be reduced in long-term operation, and it can significantly improve production efficiency in large-scale production.
Traditional welding: The equipment cost is relatively low, the technology is mature, and the maintenance cost is relatively low. However, it is necessary to consider the requirements of manual operation skills, welding efficiency, and post-processing costs (such as polishing, stress removal, etc.).
5. Environmental Protection and Safety:
Laser welding: The welding process produces less smoke and harmful substances, and the working environment is relatively good, but the safety protection requirements of the laser itself are high.
Traditional welding: It usually generates a large amount of smoke, toxic gases, and radiation heat, requiring comprehensive ventilation, smoke exhaust, and protective measures.
There are significant differences between laser welding machines and traditional welding methods in terms of process, welding quality, efficiency, and applicability. For different welding requirements, selecting the appropriate welding method is necessary to achieve better welding results.
