The method of flame cutting involves a combination of gasses to produce a controlled flame which is used to cut different types of metals. The gasses used in this process include is oxygen as well as other liquid gasses such as Nike VaporMax Flyknit Soldes , acetylene or propylene. When these gasses are mixed and ignited, they produce a powerful flame with temperatures more than 2000 degrees Celsius. The temperature of the flame is determined by the burning of the fuel gas as well as the fixed flow of oxygen.


The gasses used in flame cutting are directed onto the surface of the metal with a flame cutting torch. A chemical reaction happens on the metal sheet where the flame is directed. These gases are used to carry on the metal to melting point, not to truly melt the metal. This chemical reaction is caused by the high temperature of the metal that comes into get in touch with with oxygen. The oxygen combines with the steel to oxidize the metal immediately which produces the cut or kerfs in the steel.


In this process, the oxygen is effectively used to remove the melted metal as it is blown into the kerfs or incision on the metal with force. By adjusting the stream rate of the oxygen a variety of cuts are made.


Flame cutting is usually done at fast speed by using CNC machines which use multiple torches. This means that more than one flame cutting technique can be done at the same time, which makes it ideal for creation runs that need a high amount of exactness repeated.


This process is also known as oxy-fuel cutting and used for separating and crafting steel pieces. It is carried out by using a torch through which oxygen and a fuel gas includes, acetylene, propane or some other gases are passed. An outer ring of jets in the torch nozzle are used to preheat the bottom line of the steel. A separate oxygen flow is directed from a inner jet on to the part to be cut. Quick oxidation of the steel takes place and substance is removed by the pressure of the gases.


Flame cutting may be manual, where the cutting torch is held and guided by the operator, or automated, where the torch may be mounted on a machine. Cutting of compound figures is potential. Using Cutting machines may be pre-programmed and computer technology, to minimize substance consumption of plate being cut. Multi-cutting head machines are available for high volume creation applications.


The system of flame cutting involves a reasonable, yet resourceful way of cutting metals like steel to give them the desired shape as per the industry demands. The machines essential for flame cutting are designed to provide machining aid to small and medium scale industries that cannot afford more complex and costly forms of flame cutting.


Today a number of techniques used in flame cutting by people such as roughing cuts, gas cutting and many more. In order to form a shape due to the desired mould, we need to use one of them that suitable and easy in use.

CAPE TOWN, Feb. 5 (Xinhua) -- Lesotho's Prime Minister Pakalitha Mosisili on Friday appealed for emergency aid as a severe drought in the country intensified, putting some 650, 000 people at risk of starvation.


Most of those at risk from Lesotho's two million population are children, breastfeeding mothers and HIV patients, said the prime minister, appealing to development partners to come to the aid of his country.


"The number of vulnerable people will increase to 650, 000 while the food security situation is expected to improve only in 2017 if the rainfall pattern improves significantly for the next summer cropping," Mosisili said.


"Very little of such ploughing has happened. I have never seen so many fields lie fallow in a cropping season in this country," he said.


According to the prime minister, Lesotho needs an additional 450 million rand, or about 28 million US dollars to respond to the severe drought.


"At this point the number of food insecure people is estimated at 33 percent of our rural population. In addition, signs of malnutrition were already being observed in children," he said.


"Livestock diseases such as anthrax were being observed in some parts of the country even areas where such outbreaks are rare."


Lesotho is one of the Southern African countries hard hit by a persistent drought.


The World Food Program (WFP) estimated last month that 14 million people are facing hunger in Southern Africa due to prolonged dry spells that led to a poor harvest last year.


The WFP said the El Nino global weather event is leading to even worse drought across the region, which is already affecting this year's crop.


UNITED NATIONS, Feb. 12 (Xinhua) -- A joint statement by two UN agencies and their partners warned that southern Africa is currently in the grip of an intense drought caused by the worst El Nino event in half a century.
