Laser welders differ in a number of ways, but the biggest is the heat source. Simply put, laser welding devices heat and melt the target material using a laser beam rather than an electrical arc, plasma arc, or gas flame. 

Laser welders may employ carbon dioxide lasers, neodymium-doped yttrium aluminum garnet lasers, fiber lasers, or disk lasers. Each one has its advantages and disadvantages, but they’re all more precise than non-laser types of welders. The fine focus of a laser beam means the pool of melted material generated by the device can be carefully controlled in terms of width, depth, and temperature. That precision also matches well with computer control mechanisms which themselves are more precise than human operators. Taken together, all these advantages make laser welders perfect for high-precision projects on items like circuit boards, jet engines, medical implants, jewelry, and more.

As an added bonus, many laser welding devices can create welds in certain ceramic materials and plastics. They’ve also proven capable of welding dissimilar metals to one another. None of these things are possible with traditional welding methods.

No technology is perfect, though. Laser welding devices are more expensive than other welders with comparable power outputs. They also demand trained staff who are harder to come by than traditional welding experts. In most cases, the parts themselves need to be carefully prepared; laser welders are less forgiving of imperfect edges than other welding styles. Finally, they are actually more hazardous to eyesight than other welding devices; specialty eye protection is a must when a laser welder is operating.
