Laser Beam Welding
Laser welding uses a high-power light beam to produce deep and narrow welds. It allows fast process speeds and minimal distortion.
Physical-Chemical Mechanism
Laser welding uses a focused photon beam that delivers energy as light. The beam is aimed at the metal and creates extreme heat at the weld spot. The high energy density allows fast heating and cooling, which gives a deep, narrow weld.
Metallurgical Relevance & Welding Risks
Laser welding is great for heavy metals and high-performance materials. It keeps distortion low and improves weld accuracy. But if the laser isn't focused right, you can get uneven heating, which leads to stress and possible cracks in the material. Also, the laser light is dangerous if you don't protect yourself properly.
Workshop Practice & Instructions
To get good results with laser welding, you need to prep the weld area carefully. The material should be clean and dry to avoid porosity. Focus the laser exactly on the weld spot to get even heating. Adjust the laser speed and weld thickness depending on the material and the job.
