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 advances in forge welding‚ in which blacksmiths

A lot of skills today are looked over‚ and undermined. One of those skills is welding. Welding is more than just a blue collar job‚ and more than just sparks flying in the air. It is art. The art of joining metals and binding metals together‚ and requires more skill than the average person will ever know. Welding started in 1000 B.C. The history of welding begins with the discovery of shaping metals together from Copper‚ Bronze‚ Silver‚ Gold‚ and Iron‚ than so leading into steel. The first things

A Definition of Welding Welding is a joining process that produces a local coalescence of materials by heating‚ by applying pressure‚ or both. In essence‚ the welding process fuses the surfaces of two distinct elements to form a single unit. It encompasses a broad range of joining techniques that include fusion welding‚ solid state welding‚ weldbonding‚ diffusion welding‚ brazing‚ and soldering. The Scope and Impact of Welding Welding dates back to the earliest days of metalworking‚ and continues

"Welding With Children" Language Analysis "He just stared at me‚ and i saw that he had no idea of what late was. Glendine‚ his mama‚ probably lets him fall asleep in front of the set every night. I pictured him crumpled up on that smelly shag rug she keeps in front of the TV to catch the spills and crumbs" (2). Within the passage it mentions that the child had no idea what late was. This indicates that his life is easy because he can fall asleep whenever he gets tired without a problem like he

Prof. A.R.Santha Kumar 3.3 Welding and welded connections Welding is the process of joining two pieces of metal by creating a strong metallurgical bond between them by heating or pressure or both. It is distinguished from other forms of mechanical connections‚ such as riveting or bolting‚ which are formed by friction or mechanical interlocking. It is one of the oldest and reliable methods of joining. Welding offers many advantages over bolting and riveting. Welding enables direct transfer of

Fusion welding and non-fusion welding Fusion welding is defined as a welding process of using heat by melting the base of metals in order to joint similar types of metals together. Filler is used in this welding process to provide bulk and strength to the welded joint [1]. Whereas non-fusion welding which is known also as solid state welding is a welding process where a particular amount of heat is applied to the joining metals which essentially below the melting point of the base metals that being
