Welding has long been an important part of the economy of many cities across the globe. One of the most important places economically for a qualified welder and the trade they perform has been the state of Ohio in America. As one of the places where the steel industry in America was at its highest, Ohio has long had a need for experienced welders. This need has continued unabated no matter what economic times the country has been faced with. There are always new buildings in large cities such as Columbus or Cincinnati that will require repair for support struts and water works. There are also new construction projects being undergone all the time.

Welding and the Local Economy

Welding is a vital component of the economy of Ohio. As one of the backbone trades that keeps the state running, welding is a trade that is always necessary. Cities cannot be built without welders. Farm equipment in rural areas cannot be repaired without the capacity to weld. In a very real sense the entire state would cease to function as soon as the welding stops.

When a pipe bursts, or a vehicle needs body repair, a welder is there to fix it. Whenever an axle breaks, or a new hospital needs a water supply, a welder is there to make it happen. Without welding the economy of the region would plummet dramatically. The state needs both city and rural welding practices to continue to function, without it no new construction can begin. There will be no new buildings, no repairs to old ones. The cities would crumble into chaotic misshapen hulks and the food supply would slowly dwindle.

There are few truly vital non-medical trades in existence. The world would survive without computer tech support specialists, stock brokers, and gentlemen’s clubs. Large modern cities would have a much harder time surviving without welders and similar tradesmen.

Learning Welding in Ohio

If you’re interested in learning welding then the best plan is to look into Ohio welding schools and see what’s available. Ohio welder training is available in many places, but the important thing is to find a program that offers high quality training. If you can’t find a well respected welding school in your area, it would probably be worth it to get outside of your current area for your welding education. After all, you go to welding school to build you skills, and if you don’t get the proper training, what were you going to school for?

Ohio Technical College has been awarded top prize as the 2009 School of the Year in the 2nd annual Tomorrow’s Technician/Chicago Pneumatic competition. Ohio Technical College, a family-owned school providing technical training in a variety of transportation industries, was selected from more than 170 entries nominating 80 schools across the country. Babcox Publications’ Tomorrow’s Technician magazine and Chicago Pneumatic, a leading provider of high-performance tools and compressors, created the contest to recognize top technical colleges dedicated to innovative training programs that prepare students for real-world careers. As the top school, Ohio Technical College will receive 000 worth of Chicago Pneumatic tools and an award presentation at the school, among other prizes. “We are extremely honored to receive the 2009 School of the Year award on behalf of our dedicated staff and hard-working students, who have all become a part of the OTC family,” said Marc Brenner, president of Ohio Technical College. “Our team is committed to providing students with the advanced education and specialized skills – such as our alternative fuel and high performance courses that will help lead the transportation industry into the future. In addition to the School of the Year award, we’re also especially gratified to celebrate our 40th anniversary this year and showcase our continued investment in tomorrow’s professional technicians.” More than 1000 students are enrolled at Ohio …

If we take a look at modern industry we can see that it largely depends on the manipulation of heavy metal and alloys. Metals are being used to build the tools and transportation necessary for day-to-day businesses. Everyday huge equipments are made including cranes, cars, skyscrapers, robots, and suspension bridges using precisely formed metal components. This is because metals are extremely strong and durable and for anything that has to be big and sturdy, metal is the perfect choice.

Since the metal is so sturdy, it is really tough to cut and mend it desirably. Due to metal’s strength, it cannot be manipulated easily to form into specialized pieces. Here the plasma cutters are of great use for cutting the metals. The plasma cutter works by binding one of the most prevalent states of matter in the visible universe; plasma. The plasma cutting machines come in different shapes and sizes. There are monstrous metal cutting machines as well as portable plasma cutters.

The plasma cutter is basically a simple and relatively easy to use tool to cut steel and other electrically conductive metals. The working of plasma cutter is done using a high voltage electrical arc and compresses gas, which would normally be air. A concentrated arc of plasma is created at the cutter’s tip as an electrical arc generated by an internal electrode ionizes gas passing through a nozzle. A high circuit is developed as the arc comes in contact with the working surface thereby melting a section less than 1/16″ wide. The force of the plasma then completely blows out the molten area on the work piece. Thus a clear cut takes place without any slag. The speed at which plasma arc travels through the nozzle would be up to 20,000 feet per second and the temperature would reach as high as 30,000 degrees Fahrenheit.

Coming to talk about the power used by plasma cutters, it has been seen that light portable plasma cutters take in 110 volts with an output of around 12-35 amps. On board air compressors are often found in these machines in order to simplify their use. The large plasma cutters would have an output between 50 and 80 amps and they would be 220 volt systems. For cutting any conductive metal up to ½ inch thick, hand-held plasma cutting equipments would be available. However, for industrial purposes larger ones are used which can cut through 2 inches of metal.

There are many advantages in using plasma cutters in welding industry. One of the main advantages is that during plasma cutting the surface of the metal outside the cutting area remains relatively cool. This would help in preventing the warping and paint damage that happens with other flame cutters.  For precise curved line cutting, there are thin heat affected zone (HAZ) also allows the use of templates. Since the plasma does not rely on highly flammable gases, they have the capacity to cut up to five times faster than traditional torches. Sometimes the plasma cutters act as gougers and are capable of cutting metals accurately and quickly.
