Not indexed. Not illustrated. 1922 edition. ... fluidity of molten cast iron. The following outline covers the general procedure recommended for doing metallic arc welding on cast iron parts. In preparing a casting for this process care should be taken to remove all scale and sand by chipping or sand blasting the entire surface to which metal will be fused. A square groove is chipped along the line of the break or crack. The size of this groove depends upon the thickness of the casting and is usually 54, in., %in. or % in. square. The groove is then filled up by welding until it is flush with the face of the casting. Locate and set the first stud in the casting as close to the crack as practicable. The location of the stud is determined by the thickness and shape of the castmg and the size of the stud. The size and number of studs is dependent upon the volume of added metal required to give the necessary strength. Studs should be long enough to extend through the first layer so that good fusion can be obtained between them and the second layer. The studs should be set as close to the edge of the break and to each other as practicable. _ Weld around the first stud with a sufl1cient number of rows of deposit to reach the center of the break, as shown at X in Fig. 1. This procedure will determine the area covered by the metal surrounding one stag and will aid in locating the remaining stu s. Loicate and set the necessary number of studs to complete the job. Chip or grind grooves, as shown in Fig. 1. These grooves may be either square or semi-circular, although 1/; in. square grooves are used most frequently. Grooves should be placed between the rows of studs if more than one row is used, and at the outside edge of the weld area. Figure 1. illustrates the preparation as to grooving and...
