... environmental cracking resistance of the cobalt alloys. Three welding processes that are used for hardfacing with the high-carbon Co-Cr-W alloys, namely, oxyacetylene, gas tungsten arc, and plasma-transferred arc are also discussed. The article examines the effects of various modes of high-temperature corrosion...

... typically sustained by a low-voltage, high-current power supply, such as an arc welding supply. In this arc mode, the arc spots that appear to move rapidly on the negative electrode are actually separate arcing events that occur in rapid succession. The rate of apparent motion of the arc spot(s) is a strong...
