Welding is the process of melting metals together to form a bond. There are usually three pieces of metal you must fuse to weld.Those are the two pieces of base metal along with a filler metal. More often than not you call the pieces of base metal your work pieces. The filler metal is usually a wire, in GMAW shielded metal arc stick it is an alloy wire whereas is a TIG welding is is usually nickel or other relatively pure metal wires.
Early in the metal arc welding process the biggest problem being faced by welding is the instant corrosion of the filler metal and the immediate surrounding surface of the weld. The corrosion would decrease if not completely weaken the strength of the weld all together. What would happen is the weld would come in contact with the air the oxygen and nitrogen in the air would cause it to pit or make holes called porosity. These porosity holes were structurally unsound creating a potentially unsafe or even catastrophic failure in the weld.
In approximately 1900 A.P. Strohmenger dipped electrodes into a mixture made of lime and clay. The coating was supposed stabilize arc make it easier to control the puddle as well as eliminate the porosity.The mixture was a success in that it stabilized the arc, how ever the porosity holes were still there Strohmengers mixture were sadly not the saving grace of welding but where a great step...

...ating although moisture is still a problem we face today this process was the biggest step forward. To this day the extrusion method of making stick electrodes is the commonly practiced and most efficient.
The majority of the most popular welding methods are SMAW methods and would not be around or nearly as advanced as they are now. MIG, TIG, and Stick welding are all SMAW methods that is 3 of the 4 most commonly used methods that would not where they are now if Oscar kjellberg didn’t contribute to the art of welding without his flux mixture and production methods welds would still be weak and highly porous they would not be a staple of modern ingenuity and we would not have the ability to build the kinds of rigid structures we do now with welding. Oscar kjellberg affected welding in a very grand way he introduced the shielded metal arc welding method to the world.

- Many people may enjoy the smell of burning metal fumes but i most certainly do not!. This can be one of many problems when one is pipeline welding. I should do welding manufacturing over pipeline welding. Pipeline welding has many more disadvantages than welding manufacturing has on my body, social, and family life. What is welding some may ask. “Welding is the use of brazing or soldering to join together or split apart pieces of metal.” Says miller electric inc. The First recorded forms of welding was from the bronze age when metal boxes were made by “pressure welding lap joints together.” In medieval times welding was used by hammer to forge weapons of different types....

- Basic Welding Processes Some of the very basic processes of welding include: Gas metal arc welding, shielded metal arc welding, gas tungsten arc welding, and oxyfuel gas cutting. These processes are so unique in certain ways that it is easy to forget about all the dangers that come with welding. When there is a finished weld that is so beautiful from a process that is not really desirable, that is when it is easy to forget. “Oxyfuel gas cutting (OFC) is a process used to cut metal by rapidly oxidizing it.” (Bowditch, Bowditch and Bowditch 259)....

- 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....

- Welding Created a New World Welding is literally building a new world. The world would not be the way it is today if it was not for welding. As you look around, almost everything you see may have been welded. Welding has changed our world in numerous ways over the last hundred years, and continues to do so with the new advances and groundbreaking ways to weld. Welding is an art, science, and high paying career all in one. Welding is the most effective way to join two pieces of metal, it is the only way to join them so they act as one....

- When most people think about welding they think of it as a blue-collar, low-intelligence job, but they could not be more wrong. Welding is, admittedly, much more dirty than working in a cubicle for eight hours, but involves a huge amount of science that many don’t think about past college. The link between science and welding may sometimes be hidden by a thick layer of metal dust and spatter, but it can easily be seen if one knows where to look. Without advancements in science, there is no way that welding could be what it is today, have had the same improvements, or even be a very survivable process....

- Body What Is Shielded Metal Arc Welding Shielded metal arc welding is a manually operated welding process in which an electric arc is used to generate the heat required for welding. Shilded metal arc welding (SMAW) also known as stick welding, is a method used to join various material in a variety of applications and job locations. “SMAW is one of the oldest and most popular methods of joining metal. Moderate quality welds can be made at low speed with good uniformity” (“Welding”). It is one of the most basic and versatile welding process.... [tags: Welding, Arc welding, Gas tungsten arc welding]

- Welding and safety Welding is the process of joining metals together; there are many forms in doing welding. There are many things that have been created that have a welding process somewhere in the making for example these are a couple of things that have had welding done to be made, cars, planes, trailers, and many more things that are smaller like: metal chairs and metal tables. It was a long time before ancients had discovered a method that was made for joining metals. Workers in the ages of iron and Bronze Age began to solve the problems of forming, casting, and alloying metals (Larry Jeffus).... [tags: Welding, Arc welding, Gas tungsten arc welding]

- GMAW (Gas Metal Arc Welding) is more economic; Springer reports that “ GMAW is an economic process because it has higher speeds and higher deposition rates than manual arc welding. There is also no need to constantly change electrodes” ( Page 11). GMAW has a higher speed, which means that you can get the job done faster. It also has high deposition rates which makes the weld look clean and smooth.” This method can be used for a high range of work, but it is not suited for repair work because of it’s weld quality” (Page 4)....

Before we knew that the computer only understood what we programmed it to understand; however, now the majority of our society is learning more from computers than they are able to input into it.

- Welding is a process used to join metal parts by producing a coalescence, called a weld, at a joint. Advances in welding technology have opened the way for innovative designs in structures and machinery. Of modern welding processes, the greatest number fall under the general classifications of arc welding, gas welding and cutting, resistance welding, and brazing. Tungsten Inert Gas (TIG) welding is one of the arc welding methods. This method is suitable for many kinds of metals, but especially for welding of stainless steels, aluminum and magnesium....
