Welding with light
or dissimilar materials. Laser welders from Bielomatik Inc., Plymouth, Mich., steer beams from either CO2 or Nd:YAG lasers to the workpiece by moving the workpiece itself, moving the laser head with a robotic arm, or by redirecting the beam with two scanner mirrors, focusing optics, or wave guides. Welding...

Gas Tungsten Arc Welding
" action of the molten weld pool causing lack of fusion, along with porosity and inclusions. Gas tungsten arc welding is a thermal process which depends on conducted heat through the weld joint materials to achieve penetration. In this respect its conductance mode is similar to laser and electron...

Laser Marking Guide (.pdf)
When the laser medium is a solid crystal, the laser is known as a solid state laser. One of the differences between welding and marking solid state lasers, is the use of a Q-switch in marking lasers. This is a high speed switching element with in the resonator that can produce laser pulses down...

Featured Application: Laser Cutting Carbon Fiber Composite
it is a non-contact process, CO2 laser cutting is ideal for composites, especially when specific shapes or profile cuts are required. For this test, all runs were made using 200 watts of power at cut speeds of 120-125 inches per minute (IPM). Beam delivery to the surface of the 1 mm (0.04") thick PMC...

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...

metals remarkably cleanly, along straight or on curved paths. They can also weld two pieces of different thickness together, with a seam so small it is barely noticeable. As well, laser sources are easily adaptable to robotic systems; they can be automated so each step in the cutting or welding process...
