Principle of Metal and Plastic Welding Using Diode Lasers：
1. Metal Welding (Laser Metal Welding):
Laser welding of metals is based on the principle of localized heating and melting. When a high-power fiber-coupled diode laser irradiates the metal surface, it delivers intense energy to a small, focused area, rapidly heating it above its melting point. The molten material from the two parts fuses together, and once cooled, forms a strong weld joint.
Key characteristics:
- Deep penetration, narrow welds
- Minimal heat-affected zone (HAZ)
- Suitable for stainless steel, carbon steel, aluminum, copper, etc.
- Supports continuous wave (CW) or quasi-continuous wave (QCW) operation
2. Plastic Welding (Laser Plastic Welding):
In plastic welding, the laser passes through a transparent upper layer and is absorbed by the underlying darker or absorbent layer. The absorbed energy heats the material at the interface, causing it to melt and fuse under pressure. This is often called through-transmission laser welding (TTLW).
Key characteristics:
- Non-contact, clean welding process
- High precision, no need for filler materials
- Ideal for medical devices, automotive parts, electronics enclosures, etc.
- Works well with thermoplastics like ABS, PC, PP, and PA
Diode lasers are ideal for both processes because of their:
High electrical-to-optical efficiency
Compact size
Ability to be easily integrated with automation systems
