The apparatus used in gas welding consists basically of an oxygen source and a fuel gas source (usually cylinders), two pressure regulators and two flexible hoses (one of each for each cylinder), and a torch. This sort of torch can also be used for soldering and brazing.
Fig. 1.2. Heat intensity and heat consumption for different welding processes 1.2 DETAILS OF WELDING PROCESSES 1.2.1 Gas welding The most important process in gas welding is the oxygen in the oxygen-acetylene welding. Other fuel gases are also employed in the place of acetylene. The temperature ranges for different fuel gases are given in Table 1.2.
