What is the procedure of oxy acetylene?

The oxy-acetylene welding process involves using a torch to mix oxygen and acetylene gases in a controlled manner to generate a high-temperature flame. The flame is then directed onto the metal workpiece to melt it, while a filler rod can be added if necessary to create a weld joint. Proper safety measures, such as wearing protective gear and ensuring proper ventilation, should be followed when using oxy-acetylene equipment.

Why does glass in welder's goggles contain neodymium and praseodymium?

Neodymium and praseodymium are used in glass for welder's goggles to provide protection against harmful infrared and ultraviolet rays generated during welding. These elements help absorb and filter out the intense light produced by welding to prevent eye damage and maintain optimal visibility for the welder.

What are the methods of removing a specimen of weld from a suitable position in the joint such as a stop and start position using a non-thermal process?

One method of removing a specimen of weld , using a non-thermal process would be to use a non-themal process. A saw. The reason this is rarely used is the difficulty in cutting some metals or shapes. The sample usually taken is called a "coupon" . When taken from a pipe weld it is cut out with a torch and ground clean for inspection. to cut the same piece out of a pipe , with a saw would require too much cutting and due to the nature of the shape could be dangerous.

How do welder's glasses work?

Welder's glasses work by using special lenses that have a very high optical density to shield the eyes from the intense light generated during welding. These lenses are designed to filter out harmful ultraviolet and infrared radiation while allowing a safe amount of visible light to pass through. This protects the welder's eyes from damage and allows them to see clearly while working.

Can welders oxygen bottles be stored with propylene bottles?

No, it is not safe to store welders oxygen bottles with propylene bottles. Oxygen and propylene are combustible gases that can react violently if they come into contact with each other, leading to a fire or explosion. It is best to store these bottles separately in well-ventilated areas designated for gas storage.

What are the dangers of arc flash?

An arc flash occurs when electrical current jump from one conductor to another. An arc flash is like a spark on steroids, as it is a high energy, short duration current flow through the air.

Because of the high energy, very high temperatures are created. The air in the gap is heated and expands; the conductors at each end of the flash are heated and vaporized in less than one cycle. The resulting gas/vapor expansion is explosive and extremely hot.

The dangers to people include

  • explosive pressures that can throw people across a room
  • essentially instantaneous ignition of combustible clothing, including silks and cottons
  • severe burns, including 4th degree burns
  • death

Approximately 5% of arc flash victims die, and another 20% are permanently disabled. The remaining survivors often have not fully recovered after decades of continuing treatment, some requiring multiple surgeries each year.

In addition, the arc blast resulting from the arc flash can severely damage equipment, to the extent that equipment enclosures are shredded and become dangerous shrapnel.

Burns can effect unprotected people many yards away from the flash point, as can the blast and shrapnel.

Is a welder a physical work or is it mental?

Welding is primarily a physical job that requires manual dexterity, strength, and hand-eye coordination to operate equipment and manipulate materials. However, there is also a mental aspect to welding, as welders need to understand welding techniques, safety procedures, and interpret blueprints or technical drawings.

What element provides the coloring in the glass of welder's goggles?

The element that provides the coloring in the glass of welder's goggles is usually iron oxide. It helps to protect the welder's eyes from the bright light and harmful UV rays produced during welding.

Explain welder polarity?

Welder polarity has to do with DC (Direct Current) welders. Essentially, polarity is the direction of the current. Straight polarity means that the current is running from the electrode, to the metal, and back through the grounding clamp. Reverse polarity means that the current is going the opposite way, from the grounding clamp, through the metal, and up through the electrode.

What is stickwelding?

Stick welding is a type of welding that uses an electrical current to produce an intensely hot plasma arc that melts metal together while adding filler metal, which is what the "stick" electrode is made of. The electrode (or stick) is usually about a foot in length and is covered in flux to prevent atmospheric contamination. It is held by an electrified clamp that the welder runs across the joint to weld.

How do you use your portable welder to weld aluminum?

the only way you can weld aluminum is with AC current and high freak setting on the welder , if your welder does not have theses setting then it will not weld aluminum.

Good answer! AC is a must! The only other way is if you have an oxy/ace setup (very low psi) or alot of mapp gas, but you have to spread a flux paste on the material (looks like drywall mud) EXTREMELY MESSY!

How much is temperature on electric arc?

Temperatures in an electric arc can vary widely depending on factors like the material involved and the current passing through. Generally, temperatures in an electric arc can range from 3000 to 20000 degrees Celsius.

How do you change a 4-wire 240V plug for a dryer to a 3-wire 240V plug for a welder and which wires do you use?

The existing 4 wires meaning Red, Black, White, Bare? Red and black are "hot" (using 120V from each phase of your service entrance), white is neutral, and bare is ground. Ground the bare or green wire to the electrical box then use red and black as your hot wires and white as neutral. You must ground the welder itself also with a jumper wire in order to be safe.

What personality traits are most helpful for a welder?

Personality traits best suited to a welder are , patience , calmness, observance of detail, ability to stay in one / or many positions for some time. While these are some of the qualities most helpful to be a welder , this is only an over view. there are other things to consider, if caffeine makes you even the slightest bit "jittery" IE a bit shaky or if your hands aren't so steady, this could affect your welding ability, and the outcome of your weld.

What is the average age of a welder?

The average age of a welder varies depending on the region and industry, but typically ranges from mid-30s to mid-40s. As welding is a skilled trade that requires experience and expertise, many welders gain experience over time, contributing to the average age being slightly higher compared to other professions.

What is the average retirement age for a welder?

The average retirement age for a welder can vary depending on factors such as the individual's personal preferences, financial situation, and physical health. However, many welders retire between the ages of 62 and 67.

Can you work as a welder with a felony?

It may be challenging to work as a welder with a felony conviction because some employers may be hesitant to hire individuals with a criminal record. However, it ultimately depends on the employer's policies and the specifics of the felony conviction. It may be helpful to be transparent about your background, emphasize any rehabilitation efforts, and seek out employers who are open to hiring individuals with past convictions.
