A flux is also often used when welding wrought iron, but is not essential. Fluxes do not act as cements, but merely make the iron weldable at a lower temperature. Method of Using Flux. After the pieces in the fire have reached a yellow heat, some flux is thrown or sprinkled on the scarfs, or parts to be welded, and the heating continued up to the welding heat. As the flux melts it flows over the scarf, forming a coat or covering. This dissolves the oxide already formed and prevents further oxid...ation. 44 COMMON WELDS The flux used when welding wrought iron is generally clean, sharp sand. There are various welding compounds on the market, some of which contain borax and iron filings. Most of them contain borax, and are used mainly when weld- ing steel. Exercise 6. Practice Welds Fagot. (Plate VI. ) The Fagot Weld is given as an exercise in order that the student may (i) become familiar with welding heats, (2) learn to use the hand-hammer effectively, (3) have further practice in the drawing-out of wrought iron, (4) and also for economy, since old links, rings, or pieces of scrap iron may be used to good advantage.
