parte being forced away from each other by the pressure 

 of the blows. Other kinds of welds are recommended 

 for this .lass of work, but in most of them the blows 

 cannot be directed at right angles to the work and the 

 anvil, and consequently it is more difficult to obtain a 

 satisfactory weld. 



Fig. 10 shows the scarfing for a link or ring. It is a 

 simple form, and requires little explanation. As shown 

 in the illustration, not much scarfing is required. After 

 scarfing, ; h • two ends are brought round and overlapped. 



In welding, and indeed in any work, it is most impor- 

 tant that a firm hold be obtained with the tongs. Those 

 shown in Fig. 6a, which have slight grooves in the jaw. are 

 very pood for holding links and rings.

A method of scarfing 

 for angle welding is 

 illustrated in Fig. 11. 

 By using this scarf, any 

 required angle on the 

 inner or outer side can 

 be obtained. As in other 

 welds, the ends must 

 be slightly upset before 

 scarfing. 



Scarfing for either 

 round or rectangular 

 iron is shown in Fig. 12. 

 The upper bar, A. is 

 upset at the point of 

 scarfing by heating and 

 cooling off in water 

 except where the 



<ry^ 



upsetting is done, to localise the 

 heat. The bar is then held verti- 

 cally on the anvil and hammered 

 on the end. After every two 

 or three blows it bends, and this 

 must be corrected on the face of 

 the anvil, and the upsetting 

 proceeded with until a sufficient 

 thickness is obtained. The scarf- 

 ing of B is done by the smith 

 holding the bar with the pene in 

 position on it while the striker 

 uses the sledge. 



Fig. 13 illustrates a good 

 method of welding for certain 

 classes of work. The bar A Ls 

 heated, and with a pene and 

 6ledge. a cavity is made as shown.
