The earliest evidence of welding dates back to the Bronze Age. The earliest examples of welding that have been found to date are welded gold boxes belonging to civilizations that thrived during the bronze age. There is evidence supporting the fact that even the Egyptians developed a form of welding. Several of their iron tools were made by welding. During the Middle Ages, a set of blacksmiths came to the forefront, crafting tools, weapons and other necessities. Blacksmiths of the Middle Ages welded various types of iron tools by hammering. The welding methods remained more or less unchanged until the 19th century. Where welding methods began to resemble conventional welding processes through innovations made through
scientific experiments (Go welding: history of welding 1). Conventional welding is most easily explained as arc welding processes. Some arc welding processes are TIG welding, Stick Welding(SMAW), and MIG welding. TIG stands for Tungsten Inert Gas welding this means that using tungsten as a electrode and an inert gas, which is usually argon, the weld is produced by creating an arc between the piece being welded and the tungsten electrode. SMAW or stick welding utilizes a stick electrode held in a clamp surrounded by a powdered substance to weld. Mig welding uses a machine that holds a wire feeder within it, the wire feeder feeds the wire electrode through a tube to a gun that slowly sends out the wire as well as a steady flow of inert gas. These and other processes classified as conventional welding processes are the best processes for welding jobs because they are more cost effective, more...

...anged innumerable times over the project's life. Continual rework and time delays had hampered progress. Bolger had reported design errors that necessitated the refitting of complex equipment and rework of the aluminum welding. Materials requirements included the use of welded aluminum. Bolger normally employed only steel welders; aluminum welders were in short supply and impatient during work stoppages. The Bolger contract was cost based plus a fixed fee. A particularly disturbing problem was Bolger's cost reporting system. Bolger contract negotiators waited for up to three weeks for cost data.
Welding started back in the medieval days. But there was only one welding process, and it was called forge welding. Forge welding is the use of heating metal, shaping it (by pounding it with a hammer), then cooling it. People back then had to go to their local black smith go get things fixed. Some tasks required black smiths to be extremely precise, and have an even level of thickness throughout the piece of metal that they are foraging.
Tomorrows Welders Thomas Jefferson said, “I find that the harder I work, the less I call it work”. I have often found myself in situations where I needed to fix something but could not because it is metal. I believe this might be why I began to show interest in welding. There is great satisfaction in being able to create or fix a metal object on your own.
Welders can use hand held welders or even robotic welders to produce welds. Both equally requiring a incredible amount of knowledge. They can also fill holes, produce structures and build custom parts for automotive race shops. Welders often work fulltime on shipyards, oil rigs, and pipelines or anywhere else where a specific job is needed. Welders are often required to interpret blueprints or sketches and weld accordingly to fulfill job duties. Arc welding is the most common type of welding today and is what most welders use. (bls) There are over 100 different welding processes that a welder can learn how to use however, Stick, Tig and Mig are the 3 most common used in the industry. These are used most to maintain equipment

-Some programs are specific to certain types of pipe welding, such as shielded metal arc and gas tungsten arc welding, which are the most common welds used by pipe welders.
The first evidence of welding dated all the way back to the bronze age. The first people that found out how to weld were the Egyptians the Egyptians were smart enough to figure out how to weld. In the 19th century they figured out they could use acetylene for welding. A Englishman named Edmund Davy is the one that discovered acetylene in 1836. Then in 1880 Auguste De Meritens figured out how to fuse two lead plates together from the heat generated by an arc. Then in 1890 C.L Coffin discovered carbon arc welding which is one of the most common welding process used in today's world. Then in 1900 is were welding got introduced to a lot more advanced welding such as, seam welding, spot welding, flash butt welding, projection welding, and also electrodes were invented at the same time. A electrode is a piece of metal coated in lime to make the arc much more stable which results in better welding turn out. Then in 1919 CJ Holstag discovered alternating current. Then in 1920 P.O Nobel invented automatic welding which is a big thing in today's world. Then in 1930 New York Navy Yard developed stud welding which is used mainly for the construction industry. Then in the 1960s more welding techniques were developed such as, dualshield welding, innershield welding, and electroslag welding were
Welding is a very important tool used in our daily lives. Welding is the process of joining two metal pieces together by applying heat. A filler helps to make the joint. Everything we use from trucks to houses have some type of welding in them. There are many types of welding careers to choose from. There is a great demand for welders today. My project was to build a table and candelabra out of metal. Most of the metal I gathered came from junk yards and had to be cleaned of rust.
Welding was invented in the 1900s but lets go back a little to middle age that was when blacksmithing was the best method to use before welding. Now Edmund Davy of England was the one who discovered acetylene in 1836. Some of the others inventors were Auguste De Meritens who worked on how heating of an arc can join two pieces of metal, C.L. Coffin was one one who created a welding process with an electrode. There was other people that helped make welding more efficient. As the years past by welding was getting...
During the middle ages welding was very common. Early Egyptians learned the art of welding. Several of their tools were made by welding. A set of specialized workmen called blacksmiths created tools by melting the metal, then hammering them together. This method did not change much until the dawn of the 19th century which held major breakthroughs in welding. An open flame (acetylene) was very important to the history of welding. It allowed manufactures to make metal tools and equipment. In 1836 a man named Edmund Davy discovered acetylene which was soon utilized in the welding industries. Coated metal electrodes were first introduced in the 1900s. A coating of lime covered the electrode and made the weld much more stable. A number of other welding processes were also invented, such as seam welding, spot welding, flash butt welding, and projection welding. Stick welding also became popular around this time too. In the 1920s automatic welding was first introduced by P.O. Nobel. Automatic welding integrated the use of arc voltage and bare wire. It was mainly used for fixing old, molding metals. Several types of electrodes were also developed during this decade. A new type of welding was developed in the 1940s by Meredith. This became known as Heliarc Welding. Gas shielded arc welding or GTAW was another significant milestone in the welding history. Several advancements in the welding field were made in the 1960s. Dual shield, inner shield, and electro slag were some of the more important kinds developed. Plasma arc was also invented and was mainly used for metal spraying. Even now more techniques are being made. For example, laser welding was developed by the Russians and is being used more and more every day (“Welcome to
Welding is an important aspect of manufacturing and production. From a simple cycle to huge vehicles and machines, they all go through the process of welding at some point, in their production phase.

Submerged Arc Welding (SAW) is broadly used in Spiral Steel Pipe Manufacturing its ease of operation, flexibility and efficiency make welding a variable and attractive process in modern industries.
According to Seegrid Corporation (2012), originally, industrial robots are designed to perform operations that were too difficult and hazardous for human. Also, according to a survey conducted by PricewaterhouseCoopers (2014) on US manufacturers, 25% of the task was assembly followed by machining with 21% and the least common task being warehousing and performing dangerous tasks (both 6.5%). With the automation ability of industrial robots, it can be programmed to perform specific repetitive actions with high degree of accuracy. Industrial robots are widely used in welding applications. It has the ability to perform perfect weld joints every single time with an incredible speed that it can even outperform the most experienced welder (RobotWorx,
