... 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...

They range from the traditional (for example, oxyacetylene torch) to more recently developed processes like plasma-transferred arc. To accommodate these different overlay processes, the...

... is normally done with acetylene fuel gas. Because it is inherently slow ( Fig. 1 ) and does not require rapid response time in order to control the size of the weld pool, the oxyacetylene process is nearly always selected to initiate welder training. Greater skill is needed to control the more rapid...

In the oxygen acetylene rod method, fused ceramic material in a rod form is introduced into a 260 °C (500 °F) oxyacetylene torch. Molten ceramic is sprayed at speeds up to 170 m/s (550 ft/s) via compressed gas on the target. This...
