Shielded Metal Arc Welding

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...

Gas Tungsten Arc Welding

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 metal vapors...

Arc Welding or SMAW

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...

Name Welding 219 06 June 2013 WeldingWelding 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...

Metal Welding - Types and Processes Welding. So you think it's as simple as grabbing the gun and pulling the trigger, eh? Tell me this then - what types of welding are there? Not completely sure? Read on... Arc WeldingArc welding is a process utilizing the concentrated heat of an electric arc to join metal by fusion of the parent metal and the addition of metal to joint usually provided by a consumable electrode. Either direct or alternating current may be used for the arc, depending upon...

History of Welding

The history of joining metals goes back several millennia, called forge welding, with the earliest examples of welding from the Bronze Age and the Iron Age in Europe and the Middle East. The ancient Greek historian Herodotus states in The Histories of the 5th century BC that Glaucus of Chios "was the man who single-handedly invented iron-welding."[1] Welding was used in the construction of the iron pillar in Delhi, India, erected about 310 AD and weighing 5.4 metric tons.[2] The Middle Ages brought...

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 the metals at the meeting...

Mig Welding

What is MIG Welding? Metal Inert Gas (MIG) welding, also sometimes called Gas Metal Arc Welding (GMAW) is a process that was developed in the 1940s for welding aluminum and other non-ferrous metals. MIG welding is an automatic or semi-automatic process in which a wire connected to a source of direct current acts as an electrode to join two pieces of metal as it is continuously passed through a welding gun. A flow of an inert gas, originally argon, is also passed through the welding gun at the same...

underwater welding

UNDERWATER WELDING INTRODUCTION The fact that electric arc could operate was known for over a 100 years. The first ever underwater welding was carried out by British Admiralty – Dockyard for sealing leaking ship rivets below the water line. Underwater welding is an important tool for underwater fabrication works. In 1946, special waterproof electrodes were developed in Holland by ‘Van der Willingen’. In recent years the number of offshore structures including oil drilling rigs, pipelines, platforms...
