She used the welding arc to cut away the bypass.

Set on its lowest power, the welding arc cast a dim green light.

His black skin glimmered in the bluewhite glare of the welding arcs.

The welding arcs soon drew a crowd.

Structured laser light and monochromatic filters were used to allow an image to be seen in the presence of the welding arc.

Your welding arc scared it away.'

Welding arcs glittered.

A towering, multijointed shape rose up before the detector man, brandishing blue-white welding arcs like swords.

This often causes the welding arc to become unstable, requiring that electrode be ground with a diamond abrasive to remove the impurity.

If it is concentrated, as in the sun or a welding arc or lightning, it is extremely bright, hot, and voracious.

Sunburn can occur in less than 15 minutes, and in seconds when exposed to non-shielded welding arcs or other sources of intense ultraviolet light.

Both conditions are caused by unprotected exposure to the highly-concentrated ultraviolet and infrared rays emitted by the welding arc.

Ultraviolet emissions from the welding arc can also damage uncovered skin, causing a sunburn-like condition in a relatively short period of welding.

Carbon dioxide also finds use as an atmosphere for welding, although in the welding arc, it reacts to oxidize most metals.

Sources of UV radiation include the sun, black lights, welding arcs, and UV lasers.

"At night, it's particularly impressive, like a welding arc going across the sky," said Greg Sowell, public information officer for the Nacogdoches Police Department.

Mergon, only slightly less powerfully insulated, had to keep his variable-density goggles practically opaque against the eye-tearing frequencies of his welding arcs.

A typical value of temperature obtained in a plasma jet torch may be of the order of 50000F against about 10000F in ordinary electric welding arc.

A related process, plasma arc welding, uses a slightly different welding torch to create a more focused welding arc and as a result is often automated.

In EGW, the heat of the welding arc causes the electrode and workpieces to melt and flow into the cavity between the parts being welded.

Spark gap oscillators are still used to generate high frequency high voltage to initiate welding arcs in gas tungsten arc welding[1].

Actually all welding arcs are(partially ionized) plasma s but ,the one in plasma arc welding is a constricted arc plasma.

Sunburn is caused by UV radiation, either from the sun or from artificial sources, such as welding arcs, the lamps used in sunbeds, and ultraviolet germicidal irradiation.

Arc blow can also cause porosity in the weld, as can joint contamination, high welding speed, and a long welding arc, especially when low-hydrogen electrodes are used.

Blue-white flashes of welding arcs glimmered through its long stretch of glass windows, and the noisy chatter of riveting hammers and humming lathes came drifting out.
