MAKING A WELD
WELD STARTING POSITION
Proper positioning of the electrode is crucial to a successful weld. The CWP-11 rotates in a
clockwise direction. The weld should start on the centerline of the nozzle parallel to the center-
line of the vessel and begin welding downhill. For on-center nozzles, there are two valid start
positions, shown as A1 and A2 in Figure 3. There is only one valid start position for a hillside
nozzle, shown as B in Figure 4.
