What welding parameters to consider to produce quality weld?
There are 4 basics to producing a good weld bead.
Correct
#1 Amperage #2 Electrode Angle #3 Arc Length #4 Travel Speed
Factor in electrode manipulation in some cases.
An example of an object with pressure force area?
Our atmospheric pressure is the pressure at any given point in the Earth's atmosphere. In most circumstances atmospheric pressure is closely approximated by the hydrostatic pressure caused by the weight of air above the measurement point.
Formula: Pressure p = force F / area A
Pressure p in pascals (Pa)
Force F in newtons / square meters (m²)
Area A in sqare meters (m)
The standard atmosphere, symbol: atm, is a unit of pressure and is defined as being precisely equal to 101325 pascals.
How many watts in 500 amperes welding machine?
A welding machine rated at 500 amperes uses around 120000 watts of power. This is used in very heavy industrial applications due to its large power draw.
What is an adaptor and how is it used?
An adapter, depending on what device your using it for connects that device to the internet or a network.
Arguably the longest bridge is the Bang Na Expressway, in Bangkok, Thailand. It is 33.5 miles long (54 km), but is not considered a bridge because it does not cross a single body of water, instead crossing a river and canals.
The longest bridge running over a single body of water in the world is now the Jiaozhou Bay Bridge in China. 42km in length, it links China's eastern port city of Qingdao to the island of Huangdao. The bridge cost over $1.4 billion to build and was completed in mid-2011.
Which metal is used to make a wheelbarrow body?
They could be made of steel, plastic, they've even been made of wood in the past.
Using Ohm's Law. It is 2.5 volts divided by 5.0 ohms which is 0.5 Amperes.
What career cluster is a Marine Engineer in?
A marine biologist is a scientist. They study the Biology of marine life. The specific cluster would be a scientist - Biology - Fisheries.
Of course as with all fields of science the cluster could be narrowed down even more or expanded to just science.
What is low alloy steel used for?
It is used where cost is a big factor but high strength is still required.
What is measured by an altimeter?
An altimeter does not actually measure altitude directly, but rather just atmospheric pressure. So an altimeter is actually a barometer created for a specific purpose.
See related link The altimeter measures the height above the ground and has a pointer which is adjustable depending in which air field you are taking off on. it measures the pressure of the air as you get higher off the ground the pressure reduces therefore it is able to determine your height above ground.
What is the volume of a 1 meter square box?
I presume that the box is more than "square", that it is in fact a cube - 1 metre along all sides.
The volume of such a box is 1 cubic metre.
The area of the base of such a box is 1 square metre. If the height is anything other than 1 metre, multiply the height in metres by 1 and you will get the volume in cubic metres.
What measure equal to 6 feet is used to calculate ocean depths?
A fathom is a nautical measurement equal to 6 feet.
What is the pressure difference between space and the surface of the earth?
The surface pressure of the earth is nominally 1013.25 hectoPascals (hP), which is also referred to as 1 ATM (1 atmosphere).
The surface pressure of the earth will vary slightly according to weather conditions.
How does computer science engineering give a pathway to a better programmer?
In most universities, it's because it's a first year requirement, but in some disciplines like software engineering and electrical engineering, you will be programming, testing, and inventing new software and write reports on it.
What is the Advantage of an ac welding machine?
AC current will 'hold you' and DC current will throw you clear if shocked. Don't touch anyone if you witness them being shocked - kick them clear in a karate style or use a broom, something that won't conduct. In any event, AC or DC, a unit that can shock you is extremely dangerous and should be unplugged and the leads cut off.
How can design reviews improve designs?
By accepting reviews on a design project, whether in digital or physical medium, a designer can take critique/feedback on their project.
This critique/feedback can possibly affect the designer opinion of what looks good, and then the designer can work on the project to reach what they would consider an improvement.
still this might not be seen as an improvement to others, at which point we get into a philosophical discussion on who's point of view is correct. No one can answer that question so lets not try to.
Why are trees used to make metal?
Generally it is put there to keep animals from climbing up the trees. Squirrels for example, will eat all of the nuts and fruit out of a tree. If you put up sheets of metal about 4 feet off the ground, it will keep them from being able to climb up.
What is the highest bridge in UK?
Chenab Bridge, under construction in 2014, will be the highest railway bridge in the world. Standing 359-meters tall, and 1,315-meters long, the bridge is located between Bakkal and Kauri in the Reasi district of Jammu and Kashmir, India.
Why engineering is not suitable for girls?
This question is incorrect; engineering is as suitable for women as it is for men. While most engineering workplaces are male dominated, that doesn't mean that women can't do the work just as well. However, women wishing to go into engineering should be prepared to deal with the stereotypical view that engineers are men.
What is the lowest frequency of an LC low-pass filter?
The lowest frequency of an LC low-pass filter is zero, i.e. DC.
Why is force important in life?
Force is very important. First of all because it makes the world go round! Second, because without force we would fall of things because force pushes or pulls us back. For example, when we sit on a chair, we need force to push us and hold us so we won't fall.
What will happen rated voltage applied in transformer short circuit?
I can only answer this from an actual problem I had in relation to the question.
20-60VA 12V transformer supplying 2x20W lamps,both lamps had blown,so I bought 2x10W replacement lamps.
On replacing the lamps,when I fitted the first and tried to power up,the lamp glowed briefly,then went out.
It was only when I fitted the second lamp that both fittings lit up continuously,so in brief,the answer to the question is................the load won't operate.
AnswerThe power rating of a load should never exceed the volt ampere rating of the transformer, otherwise the resulting load current may overheat the transformer. So the situation you describe is perfectly normal.
The reason for the problem encountered by the writer of the original answer is not clear. A 60-V.A transformer should supply two 20-W lamps without any difficulty whatsoever. I suspect that the problem had nothing to do with the power rating of the lamps vs that of the transformer, and more to do with the voltage. For example, was the secondary voltage of the transformer higherthan the rated voltages of the lamps? If so, then the lamps would have burnt out.
