Making short work of small welds
for such jobs: laser, electron beam, micro-TIG or gas-tungsten arc welding (GTAW), and micro-plasma. Laser welding uses heat from a focused coherent light (laser) beam to fuse materials. In general, laser welding is appropriate when the weld joint can be accurately positioned without gaps or mismatch
