Welding is very important to society and the way we live. It is used for building the oil and gas pipeline. Also, it is used for making plane and auto parts. Most welding is done in aircraft plants and in custom fabrication shops. Other welding jobs are done on the pipeline all over America. Without welding, everyone would be without vehicles and any other form of transportation. Also, there would be no commercial buildings as welding is a major part of the foundation and structure. Our modern way of life would be completely different without welding. John Walker, from the book Modern Metalworking states that before welding to check the welder to make sure the leads and the grounds are connected properly because the temperature of the weld is determined by amps (2). There are different sizes of rods, these include eighteen gauge, sixteen gauge, ten gauge, one-eighth gauge, three-sixteenth gauge, and one-fourth gauge (Walker 30-4). When welding be sure to have the correct welding speed. Weld speed is indicated by the looks of the puddle and the ridge of the bead (Walker 30-14). Rob Timing from FabricationandWelding.com states that the filler metal fills the cavity made when …show more content…
It works by three main ingredients. Electricity, filler metal, and a form of shielding from the air are very important (gowelding para 2). “Just like MIG welding, Flux Core welding works by feeding an electrode continously to the joint” (gowelding para 2).The first step is the welder squeezes the trigger and a spool of wire is fed to the joint into the arc. As soon as the electrode hits the metal it heats it up until the wire and weld area begin to fuse together. Once the puddle is made the Flux Core creates a shield from the air (gowelding para 2). The power supply is a constant voltage power supply. This means the welding machine uses a direct current just like MIG welding, as the same machine is used for both types of
Welding is a dangerous job because you can hurt your eyes from the flash if you don’t wear eye protection. Yes pipeline welding dangerous, but it is wrong because it is only dangerous when proper safety precautions aren’t taking place. Welding is dangerous because pieces of metal can fall on you and you can get flash burn. And you can be exposed to gases, fires, explosions, and electric shock. But the only way these things happen is when safety measures are ignored.
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
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...
Oxy- fuel welding is usually called in workplace/trades terms oxy acetylene welding, gas welding and oxy fuel cutting which are all use fuel and oxygen to cut and weld metals together. It all started with the famous chemist Edmund Davy, who is suppose to be considered as the first man to make acetylene. By accident in 1836 Edmund while trying to make potassium created a black compound which was mixed with water create a gas that burned greatly. Edmund wanted to use this gas to make lights but the materials and production would cost to much. Calcium carbide was not identified until 1862. In 1892 calcium carbide was created by accident when trying to create calcium from coal tar when the production reacted with water.
There is different types of rods and different types of ways to weld. You need a lot of training for it. There are many schools and colleges you can go to receive welding education. The most common welding processes are Gas Metal Arc Welding, Flux Core Arc Welding, Gas Tungsten Arc Welding and Shielded Metal Arc Welding. The easiest of these is the Gas Metal Arc Welding. Welding options are stick, flux core, tig, and mig. The pipeline tig and stick welds a lot more than the other .The pipeline use many types of techniques but, the most common on the pipeline is downhill root pass and the up hill pass. The median annual wage of welders, cutters, solderers, and brazers is
...ignment should be preserved during welding. For the internal misalignment due to difference in wall thickness of the mating components exceeding 1/16", the thicker component should be internally machines/grounded so that the mating faces are approx. flush

Also being a welder you must know and study blueprints, maintain equipment and inspect structures also Welders or cutters must be able to work outside or in a confined area (“Welders, Cutters, Solderers”).Also be ready for the change in temperature or climate because one of the welders told me that you can either be in a huge ¨freezer¨ or outside in the texas heat. Another thing about being a welder is you must not be afraid of heights, you must wear a safety harness, a hard hat and Welders can get hurt by the arc; so they must wear a protective mask (“Welders, Cutters, Solderers”). As a welder you must Must have a good hand-eye coordination and Must have physical stamina to stand or sit for a long period of time(“Welders, Cutters,
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. Numerous things in our daily lives has been welded from coffeepots to skyscrapers. Welding can be done almost anywhere outdoors, indoors, underwater, and even space (“Welding Basics”). It is practically
The aforesaid aforesaid aforesaid aforesaid aforesaid aforesaid aforesaid aforesaid aforesaid aforesaid aforesaid afor M.I.G is something anyone can learn easily, it’s inexpensive to afford. 110v machines don't bring out the best power to weld, because these machines do not have a good duty cycle. Most people prefer 220v machines because they produce more work, even if they are more expensive. GMAW is the cheapest, most reliable process for welding. T.I.G. (Tungsten Inert Gas) is a challenging process to learn.
Engineer dates back to 1325 when an engine’er, someone who operates an engine, was referred to by a conductor as an engineer. (Ford)
As it can be seen below the fusion zone is the position the position where the base metal is melted together and combined with the weld. Root of the weld is the area at the bottom of the specimen where the welding comes in contact with the surface of the base metal. The toe of the weld is the area at the top surface of the component where a junction between the base metal and the face of the weld has occurred. The reinforcement of the weld is the excessive weld metal on the top of the surface of the specimen on the face of the groove weld.

...ts could be exposed to nuclear emission and not be harmed, so they could be replaced chemists who do the nuclear experiments. Third, vehicles manufacture requires sophisticated installation, which demand programmed robots to do the exact job. Moreover, installing vehicles parts mandate welding to wrap the parts as it could be done easily by robots. As Farum (2012) stated that robotic welding is cheaper, faster and could improve companies’ competitiveness.
