1. History of Welding a. Welding can be traced back to the Bronze Ages, where pressure welding was first developed. b. The Egyptians were also one of the first to use pressure welding. c. The blacksmith of the middle ages was the one to bring forge welding into the world. d. Early types of welding were used for holding items together for some project. As for the blacksmith in the Middle Ages it was more for horse shoes or fixing iron material for peoples equipment. 2. Types of Welders a. Arc Welder (Uses electricity to create a arc to fuse metal together) b. MIG Welder (Wire Feed Welder) [ c. TIG Welder (Tungsten Inert Gas Welder) d. Acetylene Welding (Uses Oxygen and Acetylene gas to form a flame and melt the metal to be welded. e. Spot Welder (Used for welding light metal sheets together, usually sheet metal) f. Forge Welding (Heating the metal up until its red and pounding the two pieces together until they stay together) 3. Types of Welds a. Butt Weld: (Two pieces parallel to each other) b. Lap Weld: (Pieces over lapping on top of one another) c. Tee Weld: (Is an upside-down “T”) d. Corner Weld: (Take to pieces and make a 90 degree angle, weld the corner) e. Vertical: (Going up or down) f. Horizontal: (Going side-to-side)
4. How/What Welders are Used a. Arc Welders: Used for heavier steel because of the power they have to burn through thicker compounds. Can be used on lighter metals as well if adjusted properly. b. MIG Welders: Used for light to medium duty jobs, they require the steel to be clean to get a good arc, or the weld will be useless. While Arc Welders are able to burn through rust or any impurities in the steel. Used highly in automotive industry, because of portability and ease of use. c. TIG Welders: Can be used on a wide variety of metals. It is a very precise welder; it is used in the automotive industries where more precise welding is required. d. Acetylene Welding: The welding portion of these gases is not used as much as the cutting. These torches are mainly used in the rough cutting of steel or any other metal. e. Spot Welder: Used for welding light sheets of metal together; such as in trash cans or tool boxes. f. Forge Welding: Not used much anymore, since more advanced welders have been invented.
5. Materials and Rod Use a. Each welder has its own filler rod b. Some welders have to have gas in order for them to work right c. Different rod is used for different metal, whether it be for thickness or type d. MIG welders use Argon or CO2 gas e. TIG welders use Neon gas. f. Arc welders use no gas at all; they use an electrode and electricity. g. Oxy-Acetylene is strictly gas welding, with a filler rod, which usually has a copper coating.
6. How Welding Applies to Everyone a. Everything we use has had welding as one of the key components of making it. b. Welding has made everything we do easier. c. Pick anything, and it can be somehow traced back to welding.
7. Welding and Effects on the Body a. Welding can give you a mild sunburn b. Can also cause cancer c. Fumes are toxic, and can shorten your life d. Burns are a huge factor e. The risks are very high, due to the actions involved

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 time as the wire electrode. This inert gas acts as a shield, keeping airborne contaminants away from the weld zone.…

With welding comes many opportunities along with jobs in the construction area, in the “man-made” society we live in today. Throughout all the buildings you see, bridges, and sculptures most if not all have had an element of some type of welding one to it. Whether big or small, most structures that are made of metal that is meant to last. Let's say for a community, welding is always involved. Skilled welders are always in need, more and more buildings need to be built to keep up with the population increasing in communities all over the United States. Without welders and the welding process itself, the way buildings are built, would be considerably different. Welding is used to keep metal bonded together, for walls, ceilings, and even on the equipment they use to construct what you walk into for work everyday. Welding is a necessity for buildings to keep the structure and keep…

Welding is the joining of metals. Modern welding is that there are four components. The four components are the metals themselves, a heat source, filler material and some kind of shield from the air. When considering a career in welding, a person must carefully look into the responsibilities this will entail, the skills one must have to succeed, plus another important aspects such as working conditions, salary, and the future of the job; however, just as important is to carefully seek out the Texas State Technical College will best prepare for this profession.…

The Middle Ages brought advances in forge welding, in which blacksmiths pounded heated metal repeatedly until bonding occurred. In 1540, Vannoccio Biringuccio published De la pirotechnia, which includes descriptions of the forging operation.[3] Renaissance craftsmen were skilled in the process, and the industry continued to grow during the following centuries.[3]…

Welders actually use many other tools than just a standard TIG, MIG, and stick welder. Welders on a daily basis operate safety equipment and use safe work habits, such as wear safety glasses, inspect their clothing, and wear the proper shade tint while welding. This is very important because welders can get hurt very easily by not wearing the proper safety equipment. They also examine work pieces with straight edges or templates to ensure conformance to specifications. Welders also use hand and power tools to clean welds and work on parts. Welding also involves cutting the material. Welders cut material by suing a plasma cutter or with a torch. The plasma cutter is more efficient, but the torch is much more exciting in my opinion. The main thing a welder performs is welding. Welders will perform many different types of welds. The most common type of welding is SMAW welding, which stands for shielded metal arc welding. Stick welding involves using a shade 9 or 10 level tint. Stick welding is done by turning on the machine and attaching the clamp to another piece of metal. Next the welder has to strike the arc by touching the electrode to metals that needed to be welded. A MIG welder is actually stronger than a stick welder, just from my experience welding and learning from others. MIG welding is commonly referred to as wire welding. This is also called GMAW welding, which stands for gas metal arc welding. This type…

But before starting any welding, cutting, grinding or drilling begins you should always put safety first. Having the proper clothing, gloves, shoes, eye protection, and welding helmet is crucial. Prepping metal typically begins by cutting metal to length, which could be done with a torch, sheer, or cut off wheel, all tools I use at home on a regular basis, and was trained to use in welding classes. After cutting the required pieces of metal to specified lengths, we can begin to bend and shape metal if required to do…

At one time welding was simply defined as the “joining of metals through heating them to a molten state and fusing them together” (Haynes and Storer 2). However, as technical processes have advanced, there has been a need to change this definition. The two types of welding that currently exist are fusion and non-fusion welding. Fusion welding is the most common type of welding and involves melting the parent metals that are being joined. Non-fusion welding is completed by…
