Arc Welding or SMAW Generally known as stick or arc welding. Arc welding is the most basic of all welding types‚ is easy to master in a home welding situation. Stick welding can be used for manufacturing‚ construction and repairs‚ very much well suited for heavy metal size 4 millimetres upwards. Thinner sheet metals and alloys are usually more suited to the mig welding types. STEPS: 1. Gather your materials. You should have a welding machine‚ electrode holder with lead‚ ground clamp with lead‚

Basically welding is just the cutting and joining of metal by applying heat to pieces of metal and fusing them together to form a permanent bond. Welding is used in a lot of processes such as; shipbuilding‚ automobile manufacturing and repairing‚ aerospace applications and many others. In addition to that welding is also used in construction to join steel beams of buildings and bridges and pipes in pipelines. Welders work in a wide variety of industries‚ from car racing to manufacturing. The work

Gas Tungsten Arc Welding The Process Gas Tungsten Arc Welding‚ also known as Tungsten Inert Gas Welding‚ is an arc welding process that uses a non-consumable tungsten electrode to produce a weld. The weld area is protected from atmospheric contamination by an inert shielding gas‚ such as argon or helium‚ and filler metal is normally used‚ except in autogenous welds. A constant-current welding power supply produces energy which is conducted across the arc through a column of highly ionized gas and

Homework research assignment Welding With the aid of a neat diagram explain what electric arc welding is. The dictionary defines electric arc welding as “A technique in which metals are welded using heat generated by an electric arc.” It is a type of welding that uses a welding power supply to create and electric arc between an electrode (the dictionary defines electrode as “A conductor through which electricity enters or leaves an object‚ substance‚ or region.”) and the base material to melt

Being a welder is a great occupation What is welding‚ and how does it work? Not many people know what welding is or how it works. According to Mary Bonk“welding is the process of heating and melting metal parts to join them together” (Bonk‚3). A welding machine uses electricity to melt the electrode‚ fusing one piece of metal to another. The welding machine uses a ground that connects to the surface that allows the welder to create a flowing currant passing through the electrode and

Shielded Metal Arc Welding (SMAW) is the most widely used welding process in the small scale industries‚ because of its low cost‚ flexibility‚ portability and versatility. Shielded metal arc welding is one type of welding process which uses consumable electrode consist of filler core rod coated with chemicals that will help during welding by providing flux and shielding. This process give pure and clean weldment that has high material deposition rate compared to traditional welding process. The SMAW

term‚ which covers processes such as welding‚ brazing‚ soldering‚ adhesive bonding‚ and mechanical joining. These processes are an important and necessary aspect of manufacturing operations. This paper deals with one topic in particular ‘Welding’. Welding is a process for joining similar metals. Welding joins metals by melting and fusing the base metals being joined and the filler metal applied. Welding employs pinpointed‚ localized heat input. Most welding involves ferrous-based metals such as

Name Welding 219 06 June 2013 Welding “Welding is a process critical to our present state of civilization and technical advancement‚ yet little understood and most often taken for granted” (Haynes and Storer 1). We are constantly hearing through television and other media sources that the job market for people trained in some sort of vocational skill is in very high demand. Media advertisements are encouraging students to consider a vocational skill when looking at their future. Welding is one
