Flame & Combustion. Prabir Basu. Page 2. WHAT IS A FLAME. Flame is a zone of intense chemical reaction with liberation of heat and light. What is combustion. Combustion is a exothermic oxidation of a fuel at high temperature. C + O. 2. = CO. 2. - Q. Page 3. Flame types. Diffusion flame. Premixed flame
Summary: There are three basic flame types: neutral (balanced), excess acetylene (carburizing), and excess oxygen (oxidizing) as shown below. A neutral flame is named neutral since in most cases will have no chemical effect on the metal being welded. A carburizing flame will produce iron carbide, causing a chemical
obtain a heating flame. The popular gas combinations are oxy-hydrogen mixture, oxygen-acetylene, etc. different mixing proportion of two gases in a mixture can generate different types of flames with different characteristics. 5.2.2 Oxy-Acetylene Welding. Oxy-acetylene welding can used for welding of wide range of metals
WELDING TORCH & BLOW PIPE. A welding torch mixes oxygen and acetylene in the desired proportions, burns the mixture at the end of the tip, and provides a means for moving and directing the flame. There are two types of welding torches, namely: a) High pressure (or equal pressure) type b) Low pressure (or injector)
Chapter 1 Oxygen-fuel gas plant safety 1. Chapter 2 Oxygen-acetylene and propane equipment 9. Chapter 3 Oxy-fuel gas welding ..37. Do not use heat on any container that may. have contained fuel. Fuel gas. Maximum flame.
The equipment is more portable than most other types of welding rigs. (e.g. TIG welding). • Oxy-acetylene equipment can also be used to "flame-cut" large pieces of material. Disadvantages of Oxy-Acetylene Welding. • Oxy-acetylene weld lines are much rougher in appearance than other kinds of welds, and require more
TYPES OF FLAMES. • When acetylene is burned in air, it produces a yellow sooty flame, which is not enough for welding applications. • Oxygen is turned on, flame immediately changes into a long white inner area (Feather) surrounded by a transparent blue envelope is called Carburizing flame (30000c). • This flames are
4. Oxyfuel-Gas Welding. Three different types of flames can be obtained by varying the Oxygen to Fuel Ratio. Neutral Flame. Carburizing Flame. Oxidizing Flame. Chapter 31 - 10. Oxyfuel-Gas Welding. Neutral flame [1:1 to 1.15:1 ratio] – all reactions are carried to completion: ? Most welding is done with a neutral flame.

Types of Flame. Introduction to Flame. Flame is mostly found in Gas Welding type mainly in Oxy-Acetylene Welding (OAW). Oxy-Acetylene Welding (OAW): It is a type of gas welding in which coalescence Is produced by heat obtained from burning a mixture of oxygen and acetylene gas (Gas Flame) with or without
