Manual metal arc welding (MMA or MMAW), also known as shielded metal arc welding (SMAW), flux shielded arc welding or stick welding, is a process where the arc is struck between an electrode flux coated metal rod and the work piece. Stick welding setup. Electrode 3. When the arc strikes between the coated electrode (by means of an electrode holder) and the piece to be welded (base material), it generates heat which causes rapid melting of … diameter. On a frame, you want as little heat as possible. Cables, cable connectors 5. AC or DC machine 2. Gas metal arc welding (GMAW), sometimes referred to by its subtypes metal inert gas (MIG) is a welding process in which an electric arc forms between a consumable MIG wire electrode and the workpiece metal(s), which heats the workpiece metal(s), causing them to fuse (melt and join). Aprons, sleeves, etc. 1. Due to continuing improvements, actual product may differ slightly from the product described herein. If you can’t gas metal arc weld it, then I would suggest using a small-diameter electrode, such as 0.09375-in. Processes Stick (SMAW) Welding 155095F 2018−04 Guidelines For Shielded Metal Arc Welding (SMAW) For product information, Owner’s Manual translations, Electrode holder 4. Both direct current (DC) and alternating current (AC) are used for electric arc welding process, each having its particular applications. So, let's start with the definition first. Arc welding power source. Hand gloves 11. Plasma Arc Welding is a liquid state welding process. When these measures are overlooked or ignored, however, welders can encounter such dangers as electric shock, overexposure to fumes and gases, arc radiation, The heat-affected zone (HAZ) is much greater with shielded metal arc welding (SMAW) and much more concentrated with GMAW. Safety goggles 10. Gas Tungsten Arc Welding. Wire brush 8. Page 1 Arc Welder - 120 Model 40388 Set up And OperAting inStructiOnS Diagrams within this manual may not be drawn proportionally. Arc welding is a welding process that is used to join metal to metal by using electricity to create enough heat to melt metal, and the melted metals when cool result in a binding of the metals. Gas tungsten arc welding, also known as tungsten inert gas (TIG) welding, is an arc welding process that uses a nonconsumable tungsten electrode to produce the weld. Earthing clamps 7. 3. Chipping hammer 6. Few of the important components of arc welding setup are described as under. Here in this paper, we are going to study the Components and Working Principle of the Machine, along with the Applications, Advantages, and Disadvantages of Plasma Arc Welding. Stick welding setup consists of the following equipment: A welding machine; Welding leads (Work Cables) Electrode holder; Ground clamp (Work Clamp) Welding rod (Electrode) The diagram below shows these components in their proper arrangement. Peter Smith, in The Fundamentals of Piping Design, 2007. Arc welding with coated electrodes is a manual process where the heat source consists of the electric arc. The basic circuit diagram of arc welding is given below: Equipment. The various equipment used are: 1. Helmet 9. However, some common tools of arc welding are shown below in Fig. Arc welding is a safe occupation when sufficient measures are taken to protect the welder from potential hazards. It is a type of welding that uses a welding power supply to create an electric arc between a metal stick ("electrode") and the base material to melt the metals at the point of contact. Both the rod and the surface of the work piece melt to create a … The filler metal is added from an external source, usually as bare metal filler rod.
