Classification Welding & Cutting

Up to this time a lot of classification methods used in the welding field, is due to the agreement in such matters. In the conventional ways of classifying these at this time can be divided into two groups, namely the classification based on the work and the classification based on energy use. The first classification divides molten weld in the welding, welding press, welding and other welding. While the second classification distinguishes the groups such as welding, chemical welding, mechanical welding and so on. If a more detailed classification is held again, then both of the above classifications will be mixed and formed groups are aplenty. Between the two ways of classification mentioned above classification seems to work more widely used because it is the classification described in this chapter are also based on the way to work. This classification is based on the wel ding can be divided into three main classes, namely: Liquid welding, welding and soldering press.Welding welding how in which the liquid is heated to melt the connection with the heat source of an electric arc or gas flame burning sources.

1. Welding welding press is the way in which connections are heated and then pressed up into one.
2. Soldering welding is the way in which the connection was tied up and put together programs so use a metal alloy having a low melting point. In this case the parent is not involved melting metal. Cuts are discussed in this book is how to cut metal that is based on a cut metal melt. Way that is widely used in welding and cutting with oxygen gas by the electric arc cutting. Welding is the most widely used at this time is a liquid with arc welding gas.

If held longer and more detailed classification, then the two classifications above and will form groups are aplenty. Between the two ways of classification mentioned above classification seems to work more widely used because it is the classification described in this chapter are also based on the way to work.

This classification basic welding can be divided into three main classes, namely: Liquid welding, welding and soldering press. Welding manner in which the liquid is heated to melt the connection with the heat source of an electric arc or gas flame burning sources. How welding press is where the connection is heated and then pressed up into one. Which soldering welding connection is tied to and incorporated programs so using a metal alloy having a low melting point. In this case the parent is not involved melting metal.

Cuts are discussed in this book is how to cut metal that is based on a cut metal melt. Way that is widely used in welding and cutting with oxygen gas by the electric arc cutting. Welding the most used at this time arc welding with gas liquid. Because it both ways, namely electric arc welding and gas welding will be discussed separately. While welding ways that would otherwise be grouped in a single subject. Cutting, because it is a separate issue then the discussion is also carried out separately. Below is the classification of the welding means:

a) Welding of liquid

1. Gas welding
2. Electric welding slag
3. Electric welding gas
4. Thermic welding
5. Electron electric welding
6. Plasma arc welding

b) Welding press

1. Electric resistance welding
2. Welding point
3. Sectional welding
4. Arc welding press
5. Press welding
6. Blunt press welding
7. Press the gas welding
8. Wrought welding
9. Friction welding
10. Explosion welding
11. Induction welding
12. Ultrasonic welding

75 Years of Shaping the Sheet Metal Fabrication Industry

HICKORY, NC - In an era dominated by constant technological and economic change, it is rare to find a technologically based company that has been around for 75 years, much less one that has been a leader in innovation the entire time. But Murata Machinery USA, Inc., located in Charlotte, NC, has been a world leader in forming machinery technology, specializing in sheet metal fabrication applications, service and sales of turret punch presses and material handling equipment.

For 75 years, Murata has been a pioneer in the sheet metal fabrication industry, with innovations dating back to the first turret punch press without a center post, the R2. The R2 was designed in 1932 and manufactured for production in 1934 by Theodore Wiedemann.

Wiedemann was a master machinist from Germany who first set foot on American soil in 1888. By 1916, Theodore and his brother launched Wiedemann Machine Company in Philadelphia, which made machines that were ahead of their time, designing and producing devices ranging from automatic meat slicers to paint filling machines.
In the 1930's the company narrowed its focus to the precision fabrication industry with the turret punch press.

By World War II, demand for aviation parts fueled a period of explosive growth for the Wiedemann Machine Company. After the war, the company continued its flair for innovation by unveiling the first numerically controlled machine, the A15, at the IMTS show in Chicago in 1955. By 1958, Wiedemann Machine employed 280 craftsmen and a line of turret punch presses that were renowned throughout the sheet metal fabrication industry for their durability and accuracy.

In 1964, the Wiedemann Machine Company was purchased from the Wiedemann family by the Warner & Swasey Company, which introduced the first CNC turret punch press, the Wiedematic W2040, at IMTS in 1970. That same year, the Warner-Swasey Company launched a joint venture with Murata Machinery Ltd., located in Kyoto, Japan. Blank sheet production was raised to new levels with the introduction of the first CNC Right Angle Shear in 1976, the RAS 412. Murata Warner Swasey also unveiled the world's first Flexible Manufacturing System (FMS) at Mitsubishi Switchgear and the first compact, numerically controlled turret punch press, the Centrum-1000, in 1983.

After recognizing the future potential and value of the Wiedemann Division, Murata Machinery Limited purchased the entire Wiedemann line from Warner-Swasey in 1989. In 1990, the two companies merged, forming equipment lines branded under the Murata Wiedemann name. Eventually, the Wiedemann name was phased out but not forgotten. Today, Murata Machinery continues to offer a wide array of machine tools marketed under the parent company of Muratec. Each machine also features the Wiedemann name.

In 1994, Murata Machinery changed the evolution of the turret punch with the introduction of the first electric servo punch drive — the Motorum 2034 design — which has since become a standard in the industry. Murata also launched revolutionary changes in productivity with the introduction of the first turret punch featuring a turret changer, the NPS-01, and the Motorum 2558 Hybrid, which combines electric turret punch capabilities with laser contour cutting.

That same spirit of innovation, durability and accuracy live on in Murata Machinery USA. "We always listen to the needs of our customers and react with products that push them ahead of the competition," explained Lloyd Keller, National Sales Manager, Murata Machinery USA. "Our products are designed as a solution to the user's requirements for the future that addresses improving efficiency, profits and the environment."

Today, Murata Machinery USA remains committed to the traditional values of craftsmanship with engineered products for the future. The company's sheet metal forming division produces and markets a wide range of machines, with punching capacities ranging from 22 to 45 U.S. tons. The machine configurations range from hydro-mechanical to the new servo electric drive with contouring options of plasma and laser, as well as a full line of stockers, loaders, and sorting equipment.

Murata Machinery USA's Motorum line also offers the latest in sheet metal fabrication technology and reliability, with automation options that take unmanned productivity to new heights with exceptional returns on investment. The division's equipment is distributed throughout the United States, Canada, and Mexico by the Muratec dealer network, which also provides service support.

Murata Machinery USA, Inc. is a subsidiary of Murata Machinery Ltd., located in Kyoto, Japan. The machine tool division produces a variety of metalworking machines for the metal-forming and metal-cutting industries and continues to be a world leader in the manufacture and design of high-productivity metal working machines.
