An oxy-acetylene welding torch is used for welding rather than a flame from firewood because it is possible to concentrate the energy and heat at one small precise location, to move it readily, to generate a lot of heat in one small area, to control the amount of heat precisely, and to control the amount of oxygen in the flame and therefore the oxidation occurring at the weld.
What else can I help you with?
Purpose of oxy-acetylene welding?
You have oxygen and acetylene to blend into the tip for a flame. It will be regulated by adjusting the regulators on the bottles and the welding handle will have adjusting ability for the temperature you need for the metal you are welding.
Why is the flame of beryllium colourless?
The flame of beryllium is colorless because beryllium does not emit visible light when it is heated. Unlike other metallic elements that can produce characteristic flame colors due to electronic transitions, beryllium’s electronic structure does not allow for such transitions in the visible spectrum. Instead, any energy absorbed may result in excitation of electrons to higher energy states, but these transitions involve higher energy photons, which are outside the visible range. As a result, beryllium appears to burn without producing a colorful flame.
How do you prove that candles use oxygen?
Light the candle and put a glass jar over it. Watch the flame of the candle closely. When the flame goes out, this means that the flame must have oxygen to burn the candle. This is how candles use oxygen.
What is the purpose of the flame that is lit below a hot air ballon?
That flame is the source of heat for the hot air in the hot air balloon.
Name two things that Leonardo planned or designed?
He designed The Mona Lisa and the flame thrower i think
Why welders use welding torch not the flame of firewood in welding?
Welding involves melting metal. Wood flames don't get hot enough.
Is welding equipment fireproof?
No. Cables for electric welders, and hoses for gas torches are fire RESISTANT, but can be burned. Care should be taken to shield them from direct flame, and spatters of molten metal.
What has the author John P Stewart written?
John P. Stewart has written: 'The welder's handbook' -- subject(s): Handbooks, manuals, Welding 'FLAME STRAIGHTENING TECHNOLOGY FOR WELDERS' -- subject(s): Scarfing (Metals), Metal straightening, Oxyacetylene welding and cutting
How to Find a Welding School?
Welding is a process in which metal parts are joined together. Welding is a skill that requires patience, a steady hand, and attention to detail. Welds may be made by use of a gas flame, an electric flame, or more recently by use of a laser. For years, welding was taught on the job. Experienced welders educated the novice welders, passing the craft down from one generation to the next. The increased demand for quality welders has necessitated the inception of quality welding schools. There are a number of welding schools across the country with the mission to properly prepare students to enter the workforce with the knowledge and ability to be successful welders. A good welding school should offer hands-on curriculum, coupled with intensive classroom instruction taught by experienced and qualified teachers. These teachers are usually experienced welders and not college professors. Many of these welding schools offer job placement assistance. They may work closely with the construction industry. Training is relatively short, and can usually be completed in six to twelve months. There are schools who offer shorter training, but most experts agree that several months of training is usually necessary. While there are schools who deal exclusively in welding applications, many trade or technical schools offer welding training. Training may also be received in the armed forces. During the training, welding students may complete coursework in metallurgy, blueprint reading, and math related courses. Safety instruction should be a core part of the curriculum. With proper training, welders can expect to secure employment in a variety of jobs. Welding is an integral part of shipbuilding, automotive manufacturing, power plants, bridge building, the aerospace industry, construction, and many other applications. Due to the nature of the work, the majority of welding is performed outdoors, often in working conditions that may be considered less than ideal. Because of the working conditions and the importance of the job, qualified welders are in high demand. This demand is expected to continue for several years to come. It is not uncommon for welders to make in excess of $40,000 annually.
For welding high carbon steel which type of flame is used?
carburizing flame is used
What is the hottest part of a welding flame?
It is just at the end of the blue flame that comes from the tip.
What type of welding is when metal is fused together by the heat of a welding flame?
It's called Fusion Welding. You answered your own question.
What type of flame using inbrass welding?
nitrajen
What is the use of oxidizing flame?
An oxidizing flame is used in metalworking to add oxygen to a flame, which increases the combustion of materials being worked on. This helps to remove impurities and produce cleaner and brighter metal surfaces. It is commonly used in processes such as welding, brazing, and soldering.
What types of flame are obtained in oxy-acetylene gas welding?
When the correct amount of Oxygen is mixed with the Acetylene a NEUTRAL flame is produced. Less than that amount produces a CARBURIZING flame. Too much Oxygen creates an OXIDIZING flame. Most welding/cutting is done with a NEUTRAL flame but all flame adjustments have their purpose.
Starting a Career as a Welder?
Welding is the process of joining metals by use of either a gas or an electric flame. More recently, that process has been expanded to include welding by use of a laser. Welding is an integral part of the construction industry. Welders are needed in the fields of shipbuilding and in the automotive industry. Often, welders may find themselves employed as bridge builders or in manufacturing facilities. Highly qualified welders may obtain employment in power plants or in the aerospace industry. In the past, welding was taught on the job. Older, experienced welders passed down their craft to novices. As the demand for qualified welders has increased, so has the opportunity to receive proper training. A number of trade and technical schools and some community colleges have begun to offer welding programs. These programs can typically be completed in just six to nine months. In most trade schools, classes are taught by qualified, experienced welders. Generally, these trade schools are in close contact with employers and offer job placement assistance to its graduates. Training may also be received in the armed forces. The building trades industries may offer training, education, and apprenticeship programs for those who desire a career as a welder. For apprentices, welding may be included as a part of training in another craft such as ironworking or machinist training. Welding schools generally provide training in all types of welding applications. Classes may also be taught in basic metallurgy, mathematics, and blueprint reading. Graduates are usually ready to take their place in the work force. There exists a high demand for qualified welders, and this trend is expected to continue. Welding is often performed outdoors, and may be performed in harsh weather conditions. Couple these factors, with the demand for highly qualified welding, and it is easy to see why welders often receive excellent compensation in the way of salary and benefits. Because of the nature of the job, overtime can be expected. Nationally, the average annual salary for a welder is around $38,000. With additional experience, this salary is likely to increase.
Which gas welding flame is the hottest?
It's called a Neutral flame. Enough Oxygen is added to the fuel to allow almost complete combustion. The remaing fuel is combined with the surrounding air and burned. This is the best flame for most cutting and welding operations. Too little Oxygen produces a Carburizing flame. It is yellow and produces smoke. A slightly Carburizing flame is used when welding Aluminum. Too much Oxygen produces an Oxidizing flame. It begins to sound louder and the inner flame comes to a point.
