This article sets out to describe the various types of welders are used in industrial metal fabrication and applications of each. Welder can be divided into two categories: those who use fire to heat sources and the use of an electric arc. Flame welder consists of four main parts: compressed gas cylinders, regulators, hoses, and handles. Gas cylinder containing a fuel and oxidizer. Acetylene and oxygen are combined fuel oxidizer most common, but many people use propane for fuel because of the relative instability of the Acetylene. Each cylinder has a manual valve which when opened allows the gas to flow into the regulator. Each gas cylinder has an adjustable regulator that reduces gas pressure from the higher cylinder pressure to a pressure consistent. Set the regulator allows adjustment of the flame. The regulator is connected to the butt weld with a rubber hose. This Handbook contains the on / off for both acetylene and oxygen valves, and threaded adapter to allow attachment welding range, brazing, cutting and tips. Because of this design gas welding outfit is the most versatile - with the right accessories almost any operation can be completed. A skilled operator can weld thin metal with precise control of the welding flame. Gas welding can easily result in contaminated welds when the operator is not diligent and the flame is not set correctly.
Arc welding machine is broken down into three categories, based on the electrode material and type of protective gas. SMAW is the most simple process, which stands for shielded metal arc welding. An electrode holder clamps long metal electrode coated in flux mixture. Arc is struck between the electrode and the workpiece. Metal electrodes deposited to fill the weld, and flux of shielding gas to burn and create. GTAW welding, or more commonly referred to as TIG welding, Gas Tungsten Arc Welding stands. GTAW welding uses inert gas, usually argon and CO2 mixture to prevent the weld from being contaminated by oxidation. The Tungsten on tungsten electrode which GTAW stands used to support the welding arc. Workpiece is the negative side of the circuit, and the tungsten electrode is formed on the positive side, which is contained in the handle, called a 'torch'. The operator manipulates the welding arc voltage using a foot control pedal and by varying the distance of the torch from the work. Welding is filled in using welding rod. This technique is similar to gas welding. GTAW welding is slow, but allows for a high degree of precision and the welding of exotic metals like titanium. Stands for GMAW welding gas metal arc welding, also known as MIG welding. Instead of tungsten electrodes and filler rods separate the two combined. A metal electrode continues to eat a good idea to support an electric arc and add filler metal to weld. Inert gas welding shield and prevent contamination, such as in GTAW welding. GMAW welding fast and versatile. FCAW flux cored arc welding stands. Feeding mechanism employing FCAW GMAW welding electrodes together, but instead of inert gas to protect the welding wire containing flux, which when burned creates clouds shielding gas around the weld.
