Application
The arc at high speed
Metal transfer, arc stability and the weld pool seen through the glare, with laser illumination.
The challenge
The arc is too bright for any ordinary camera, and droplet transfer happens in milliseconds. Seeing the weld pool, the wire and the droplet takes a high frame rate, a short exposure and laser illumination with a filter in the same wavelength band.
What the camera needs to deliver
5,000 to 20,000 fps
for metal transfer
Droplets, short circuit and spray, frame by frame.
Laser
pulsed illumination
Eliminates the arc glare with a bandpass filter.
Compact
for robotic cells
KT and T-Series fit next to the torch.

Case studies and featured research
Featured research
Weld joints under 1 mm at LPTS, Universidade Federal do Ceará
The LPTS, from the Department of Metallurgical and Materials Engineering at UFC, develops new arc welding processes and uses a Phantom v711 to record weld joints smaller than 1 mm in diameter, on manual and robotic equipment.

Frequently asked questions
Does it need special lighting?
Yes. Pulsed laser illumination with a filter in the same band is what makes it possible to see through the arc.
