Grit blast worn flange area to be repaired.
SUBTASK 72-45-24-120-001 Grit Blast the Repair Area
Refer to SPM TASK 70-34-03-340-501.
For wear up to a maximum depth of 0.030 in. (0.76 mm), plasma coat the area.
Refer to SPM TASK 70-31-13-310-501.
For wear up to a maximum depth of 0.030 in. (0.76 mm), weld build up the area by the Manual Gas Tungsten Arc method. Use CoMat 03-197 WELDING FILLER WIRE. Use of cooled cooper chill block during the welding process is recommended to minimize flange distortion during welding.
