Airco welding of locomotive fireboxes . he firebox. Then weld on the water side from 1 toA, back weld from 2 to 1, 3 to 2 and so on to the flange at B. WELDING THE DOOR SHEET KNUCKLE CRACK OF FIGURE 59: Operation 4. Working from inside of firebox, weld from 1 toA, back weld from 2 to 1, 3 to 2 and on across to 8 and B. The dis-tance between tack points of weld should be about 10. Figure 60gives the form of vee for the butt weld. WELDING THE FLUE SHEET PATCH OF FIGURE 61: Operation 5. Weld the flange at A. Then back weld from 2to 1, and on to B. WELDING THE FLUE AND SIDE SHEET PATCH OF FIGURE 6

WELDING THE DOOR SHEET KNUCKLE CRACK OF FIGURE 59: Operation 4. Working from inside of firebox, weld from 1 toA, back weld from 2 to 1, 3 to 2 and on across to 8 and B. The dis-tance between tack points of weld should be about 10. Figure 60gives the form of vee for the butt weld. WELDING THE FLUE SHEET PATCH OF FIGURE 61: Operation 5. Weld the flange at A. Then back weld from 2to 1, and on to B. WELDING THE FLUE AND SIDE SHEET PATCH OF FIGURE 62: Operation 6. Cut the side sheet to outside of the rivet holes, asshown in drawing c. Weld the flange at A, and then back weld downto the flange at C. Now weld from 6 to 5, 7 to 6 and so on to B. Xote: The flue sheet weld of Figure 63 should be performed as describedfor Figure 55. Crack C of Figure 64 should be welded the same as that of Figure 55, whilePatch D may be welded in place by the method shown in Figure 61. Page Twenty-nine. Page Thirty T AIRCO BUILDING-UP OFWORN EDGES OF FIREBOX HE EDGES OF fireboxes become worn, and cause leaky joints,from excessive caulking, erosion from escaping steam and cor-rosion. The restoration of these edges by building-up may be accom-plished as follows, using an Airco cutting torch with No. 1 tip, anAirco welding torch with a No. 8 tip, and Airco 3/16 or 54 weld-ing rod. Operation 1, Figure 65. Brush the rust off the edge of Figure65 and build up from 1 to 2. Light hammering of the weld whilered hot will improve the joint. Operation 2. Figure 66. A piece rusted out as shown in thisfigure may be built up by first removing the rivets 1, 2 and 3, andthen adding metal from a down to the bottom of the sheet to the mud-ring. Operation 3, Figure 67. In welding sheets to a mudring buildup the joint of the two sheets for about 5 above the bottom. Bevelthe bottom of the sheets as shown in Figures 68 and 69. Page Thirty-one
