Introduction
MIG welding, the most preferred and most efficient way of welding today’s vehicles, because of the more heat-sensitive metals and the use of thinner gauge this type of welding is recommended in all body shops.
This is a wire-feed, fusion welding process that releases

When you’re welding on the other hand it the technician is required that he/she has safety glasses a welding helmet, welding gloves, a respirator, and a welding jacket. When you are MIG or arc welding you are vulnerable to hazardous fumes, if not wearing a dry hole free insulated gloves you can put yourself in a position of being badly electrocuted. Always wear a respirator, if inhaled the potent toxic fumes that are released can cause drastic damage to your lungs which can cause you to contract cancer. When plugging in your Millermatic MIG welder be sure to stay away from damp confide spaces it could cause a break out of an electrical …show more content…
When cleaning the surface use wax and grease remover, note that wax and grease remover is flammable so do not store this product near the welding area. Weld-through primer should be applied to any and all bare metal surfaces where the galvanized coating has been removed. Any undercoating, oil, dirt, corrosion, or grease must be removed from the area in which you are welding. When using weld-through primer, the excess must be removed after welding to allow the adhesion of other coatings. Types of welds
There are many different styles, techniques, and positions that welders are required to know. First before you start welding you need to know the direction you are, if you are using the push or pull technique. Second you need to make sure that your amperage and voltage are being balanced. Third you need to make sure how much wire need to stick-out. Fourth you need to figure out what angle the gun should be in. fifth identify what kind of weld needs to be performed, butt weld, lap weld, plug weld, or joint welds. Sixth what position are you required to weld in, horizontal, over-head, vertical, or flat. Seventh the travel speed determines the outcome of your welds, if your travel speed is to fast you will get sloppy splattered looking welds if your travel speed is to slow you will burn through the metal, but if your travel speed is at an even pace you will get a thick

To begin with, Study.com tells that the lowest level of education required is a high school diploma or equivalent. Many employers may require an employer- based welding test. Some employers look for a certificate or undergraduate degree from a technical school (Study.com). Next, it is important to note where training is available. WATC.edu states, that they offer a welding program. WATC is located in Wichita Kansas. Their welding program allows students to gain knowledge and skills in cutting, shielded metal arc welding, gas metal arc welding, gas tungsten arc welding, and provides some exposure to oxy-acetylene cutting and welding (WATC.edu). In addition, the length and cost of the training is an important consideration. WATC.edu shares, that there are 5 different degree and certificate options. The one I would be interested in is the Welding Technical Certificate option. This one would be a total of 46 credit hours and would cost a total of $10,524. Finally, this job requires certain traits, talents and interests. The Occupational Handbook adds, that welders often must work in awkward positions using tools, so they need to be able to put up with that. A lot of times, overtime will be present. So you would have to be available for overtime if needed. Welders are required to lift heavy objects sometimes. So a welder should be fairly strong (The OCO). I think that being a welder would be hard work. I feel that I would be able to work hard enough to be a welder. I now know what traits a person should have, in order to be a welder. In summary, there are educational and personal qualifications to consider if I want to become a
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.
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
Welding can be traced back to the ancient times. One of the earliest methods of welding is bronze age. when ancient people back then had small gold circular were made by pressured welding lap joined together. Then in the Iron Age the Egyptians and people in the eastern area learned to weld pieces of iron together. In the middle age blacksmithing was developed. Blacksmithing is when you weld a piece of metal and hammering it but it was in the 19 century that welding was invented as they know it today.
The main objective of this project was to investigate the influence of blade and clearance on the work material and the parameters affecting resistance spot welding such as heat transfer from the electrodes to the sheet-sheet interface, current requirement to achieve the necessary heat to form weld nugget and influence of clamping force on sheet welding.
When starting to weld the first thing that should pop into the mind is safety. Some of the equipment that is needed are safety glasses, welding helmet, leather jacket, and gloves. The welding helmet, leather jacket, and the gloves protect you from the harmful ultraviolet light that is emitted from welding.
One main category of welding is arc welding. Arc welding uses a current sent from an electrode, through the base metal, and back into the ground clamp on your welder. This arc creates a tiny spot of immense heat that melts the metal around it, thus creating a weld puddle, or the puddle of molten metal. Within arc welding there are MIG, TIG, and stick 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).
Welders also get insurance, but as personal benefits welders have a medium level of social contact(“Working Conditions” 1). The pay for welders is good as well, mostly because a person in this career has a chance of getting badly hurt. This career also will appeal to hands on learners, because everything in this career is hands on. There are a lot more benefits for someone who likes physical exercise, there's lots of heavy lifting involved.
Upset welding (UW) is a welding process which makes use of the resistance offered by the two metals, which are to be joined, to electricity and thus helping the metals to be fused along the butt joint or over the area in which we should make the fusion. Pressure is applied to the joint in such a way that it’s application will enhance the welding process.
Welding is the key to the evolution of life in various ways that some people will never understand. The most important events in our nation’s history could not have happened without the arts and tools created by welders around the world. Wars, cities, nations, and even continents all evolved and became bigger, better, and stronger because of the creation of welding. The smallest and the biggest structures on earth have all been touched or designed by welders across the world. We are all nearby some type of structural iron and steel working every day not even realizing it without taking a second look. Welders themselves mostly do not think nothing about the arts of welding until after they finish the job because it comes so natural to them. Welders’ jobs are not just limited to creating weapons or skyscrapers, but they also save lives and put roofs over people’s heads every day.
A welder must be issued with an appropriate flameproof boiler suit that is right size and that is made from a breathable material. P1 (b) Provision and Use of Work Equipment Regulations (PUWER) 1998 The purpose of PUWER is that it seeks to address, control and prevent workers risk of injury and death from equipment they use during the course of their jobs. Working in engineering involves the extensive use of machinery. The PUWER define work equipment as any machinery, appliance, hand tool, powered tool or assembly of components.
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
