Welding is the joining of metals. What welding does is join metals or other materials at their molecular level with the technology we have at the moment. What we know about modern welding is that there are four components to a weld. The four components are the metals themselves, a heat source, filler material, and some kind of shield from the air.

The welding process works like this. The metal gets heated to its melting point, at the same time there is some sort of shielding from the air to protecting it, and then a filler metal is added to the area that needs to be joined ultimately producing a single piece of metal.

Back in the day, when the bronze and iron ages began using metals more productively, they would use a direct casting process. The casting process would be done by making a sand mold of the piece to be added.

Once the mold was made you simply put it on top of the metal piece you wanted to add a part to, and fill it with hot molten metal, after which you wait for it to cool. Another way metal was joined was by putting two pieces of metal together and damming any open sides. Once the area was leak free you simply poured molten metal to fill the joint. When the Industrial Revolution began around AD a process known as forge welding was used. When the metal is hot enough you simply hammer them together until they fuse.

This all worked well enough until In an inventor who was awarded over patents by the name of Elihu Thomson came up with resistance welding. He was someone whom the modern world should be thankful to! Not only did he make resistance welding possible, but we still benefit from many of his other electrical inventions.

This was the beginning of the end for the mass use of rivets, screws, and bolts to join metals. At the end of the First World War new welding techniques were a closely guarded secret to the ship repair industry. Even today the welding technology used by military contractors and the new alloys produced are a closely guarded secret! It is a simple process that the industrial revolution needed and without it many of the things we take for granted would not be here!

Welding is a major need for most manufacturing industries. Almost any industry that works with metal cannot survive without welding. Welding, in a big way, is the back bone of all metal products. Every industry, from underwater construction to space explorations, relies on welding. Just look around right now how many things around you are made of metal? Welding today has four popular processes. These processes have not always been the most popular in the past but have risen as the favorite of engineers and welders for cost and practical reasons.

In the real world not a text book these are the welding processes that have the most demand job wise. Not sure?

Pick up any newspaper right now and look at the employment ads. These are the types of welders most employers need! All of the above processes require electricity to create the heat needed to weld metals. The main difference between all of these processes is the way the filler metal is added and how the weld is shielded from the air.

On a scale of 1 to 3 for difficulty, SMAW is a 2. Stick welding is the most common, but from a visual point of view it is harder to determine how much filler metal is added to the joint because the shielding on the rod produces a slag that does not allow you to see the weld directly while welding.

Afterwards, you chip off the slag to see the weld. Stick welding is also the best process to weld out doors with. The best description in a comparison point of view is a bicycle brake cable that has a wire running through that feeds continuously to the joint. But this cable also has a gas flowing through it that shields that weld from the air.

On a scale of 1 to 3 for difficulty FCAW is a 2. Flux core welding is mostly used outside when there are heavy production demands for the amount of weld done per hour.

This is commonly used in shipyards where a lot of weld is required and it is windy. The non-consumable rod is only a rod that creates the arc to heat the metal. It does not add to the welding filler material itself. On a scale of 1 to 3 for difficulty TIG is a 3. You are heating the joint with one hand and the other needs to add the filler metal.

The huge upside is total control of the weld and it is the process of choice for exotic metals and joints that needs the best weld possible.

The first main difference is that some processes feed the filler metal with some sort of wire using a mechanical feed like a wheel or spool of wire.

These are considered semi-automatic. The second is an electrode that burns down until it is finished or the processes that filler metal is added manually with the other hand. These are considered manual processes. The second difference is the way the shielding from oxygen is created.

While stick welding uses a chemical powder on the rod or electrode that burns and shields the weld. Also, this same chemical powder may contain filler metal to make a faster weld. When it comes to welding production, meaning how many pounds of wire is applied in a day, MIG and Flux Core take the prize. Second is Stick welding. Finally, there is TIG for totally precise welds that can be done on any weldable metal.

Many manufactures who are metal fabricators choose the proper welding process by weighing the minimum quality of the weld they need, versus how fast a weld can be made. Yeah, money, money, money! With MIG or Flux Core most common in welding shops and shipyards , welding of the metals is very fast because the metal comes on a spool and they are machine driven as fast as needed. Unfortunately, because the wire is feed through a cable much like the brakes of a bicycle, there is a limit how far you can go with the welder distance wise.

The further you go from the wire feed, the more friction the wire passing through the cable has. This causes some unavoidable problems. Secondly, Stick welding can be a fast-paced welding process if the welding rod is big enough or has filler metal added to the coating. The main attraction of Stick welding is that it works great outdoors and requires no bottles of gasses to shield the weld. Additionally, Stick welding machines have long cords and can weld as long as the cord is long, and short enough to keep the electricity at the proper level.

Stick welders are the most cost efficient for someone who just needs to do some metal repairs or enjoys welding is their hobby. Stick welding is the most trouble free and easy to set up. Finally TIG welding, the most respected and valued of all welding processes, is slow but the best for weld quality wise.

The downside is you need a bottle of gas to make it work and wind can cause trouble. Typically, many Stick welding machines are also TIG welders. The upside is the best quality weld with any metal. Understanding welding polarity and voltage type is important since the most popular welding process today use electricity to produce the heat needed.

There are three types of welding polarity. Almost any metal can be welded depending on the process and conditions. The people who determine what and how the metals can be welded are called metallurgists or welding engineers depending on whom you ask.

The three most commonly welded metals are steel, stainless steel, and aluminum. Outside of the more common metals that are welded there is an almost endless variety of metals produced that can be welded. The cost of these metals can be very expensive and they are considered exotic, such as Titanium that is used in the aerospace industry, Nickel-based alloys used in nuclear power plants, and endless combinations of different metals specifically engineered for a variety of purposes.

If you are thinking about a career in welding there are many types of welding and welding related positions. Welding skills are in high demand and with the world becoming environmentally friendly, it is only going to create more demand.

Some jobs can be very dirty, while others are done in an environment almost like a sterile operating room. Most welders go to work to the same place every day, while others travel around the country doing industrial shut downs earning six figures a year allowing them to take a lot of time off. An elite few welders work at the bottom of the ocean and a select few in outer space.

Many welding jobs are more than just welding. Outside of a strictly being a welder, the industry has a strong demand for people who are good at solving problems and who are good at math. Having a welding background opens many more career options and opportunities. The American Welding Society released a press release and in their words this is what they have to say about welding as a career.

January 18, — NAPS —A growing number of men and women are finding financial freedom by taking up a welding torch and beginning a new career. Many welding positions are more than just welding. This is the job I love to do because you never know what you will be building next!

Frankly, I get bored working in an office for too long, as I also get bored working with my hands for too long. Welding gives me a chance to do both and balances out my life. If you like to work with both your mind and your hands, then welding may be an excellent career choice for you too. I do want to sum it up and say that getting an introduction to welding changed my life for the better!

Out of all of the training classes I have ever taken, welding has always paid off very quickly. I remember when I took a hour welder-fitter course and was worried about paying off my student loans. In a matter of only six months, this career choice gave me the income I needed to pay off my student loans!

Welding is the joining of metals.

Arc welding is a welding process that is used to join metal to metal by using electricity to create enough heat to melt metal, and the melted metals when cool result in a binding of the metals. It is a type of welding that uses a welding power supply to create an electric arc between a metal stick " electrode " and the base material to melt the metals at the point of contact. Arc welders can use either direct DC or alternating AC current, and consumable or non-consumable electrodes. The welding area is usually protected by some type of shielding gas , vapor, or slag. Arc welding processes may be manual, semi-automatic, or fully automated. First developed in the late part of the 19th century, arc welding became commercially important in shipbuilding during the Second World War. Today it remains an important process for the fabrication of steel structures and vehicles. To supply the electrical energy necessary for arc welding processes, a number of different power supplies can be used.

What we know about modern welding is that there are four components to a weld. The four components are the metals themselves, a heat source, filler material, and some kind of shield from the air.

Until around , most covered electrodes used in Japan were imported, though leading shipbuilders and machinery fabricators were able to produce them for their own uses. Similarly, Kobe Steel also produced its own covered electrodes in-house. Around , Kobe Steel began to pursue full scale research and development of covered electrodes, acknowledging the importance of welding technology, and responding to the increased demand for domestically-produced covered electrodes.

In the years leading up to , the world economy remained strong, thanks to booming economic growth in developing nations, including China. These trends were mirrored in the welding industry, and demand for welding consumables in the shipbuilding and energy industries increased. Due to increasing demand for crude oil and other natural resources, commodity prices continuously increased, leading to ever more construction of such facilities as offshore structures for exploration and production of oil or natural gas as well as crude oil tankers,storage tanks and oil refineries. Indeed, many industries that enrich human lives prospered, including automobiles and construction of power plants, infrastructure and commercial and residential buildings. In many industries, demand increased not only for welding consumables but also for greater production capacity and automated production systems, and KOBELCO was in good position to supply both. Having developed and supplied automatic welding technologies to Japanese shipyards and related industries since the s, KOBELCO now supplied them to new overseas markets. Used together with exclusively-developed welding consumables, these technologies delivered superb performance within their respective circumstances. However, following the Beijing Olympic and the financial crisis caused by the subprime mortgage problem, this favorable business climate cooled. Enthusiasm for investment slowed, resource prices dropped, and the world economy quickly went into recession. However, while at first it seemed the adjustment phase would last long, the world economy slowly began showing signs of recovery in , thanks to continued growth in the BRICS and other developing nations.
