temperature detection port flange full welding RTJ trapezoidal groove processing,
the highlight of this work is that the upper head temperature detection port flange
heat treatment after the layer surfacing processing, the surfacing is the upside position
stacking Welding, considering the quality of surfacing welding, there are defects on
one side, and the full surfacing is used for processing, regardless of surfacing and
processing, and its workload is huge. Processing technology: using British portable
equipment to fix the equipment through flange external card, adjust the center and
flatness After turning the plane out of the reference surface, perform grooving rough
machining, and then finish machining to ensure that the pitch diameter of the groove
is ±0.13, the angle of 23°, the surface roughness is 0.8-1.6, and the flaw detection PT
is qualified.
