Already widely used in European dental laboratories as well as in other industries, it wasn’t until around 1994 that laser welding took root in the U.S. laboratory market when American Recovery, Dentaurum and Tanaka Dental all introduced laser welding units. A key benefit was the stronger connections; a 1991 study published in Quintessence found the connections to be 266% stronger than solder, 43% stronger than microplasma welds and 95% as strong as the original alloy.
Because the laser focuses a beam that melts and welds a very small area of metal, laser welders also brought a higher level of accuracy and tremendous time savings to nearly every department in the lab.
