T V approved filler metals already used in a number of plants world-wide. Further development of the martensitic steel grades have lead to new grades of steel for even better high temperature properties. MTS 616 and MTS 911 are available. In addition, Union I Cr 2 WV has been developed as a matching consumable for the welding of grade T23 ferritic bainitic steel. We have presented the development and applications of these welding alloys in numerous papers and publications around the world.

Parameter settings are similar to solid wire. However, a faster wire feed rate is required. Torch Positioning Recommended parameter settings Optimum parameter settings may vary according to actual welding conditions. Standard feed rollers with a smooth groove can be used. Adequate fume extraction is recommended as it always should be when welding stainless steels.
