CNC laser welding combines axial motion with laser control to create a thin seam weld by consistently applying a series of pulses along a continuous contour. The overlap percentage between pulses affects the sealing quality.

STI hermetically seals implantable devices and welds small cutting or probing tools to endoscopic tubes. Common applications include endoscopic and arthroscopic surgical tools.

STI also uses laser seam welding to assemble products from several components having different mechanical properties. Manufacturing orthopedic nails, for example, involves laser seam welding of hardened bars which provide structural strength onto an annealed tube that facilitates factory crimping and intra medullar expansion.
