What are the causes of slag inclusion?
Slag inclusions are nonmetallic solid material entrapped in weld metal or between weld metal and base metal. Slag inclusions are regions within the weld cross section or at the weld surface where the once-molten flux used to protect the molten metal is mechanically trapped within the solidified metal. This solidified slag represents a portion of the weld's cross-section where the metal is not fused to itself. This can result in a weakened condition which could impair the serviceability of the component. Inclusions may also appear at the weld surface. Like incomplete fusion, slag inclusions can occur between the weld and base metal or between individual weld passes. In fact, slag inclusions are often associated with incomplete fusion. Daniel
How do you calculate the stripping ratio?
We divide the overburden thickness by ore thickness to get the stripping ratio For example if we have an overburden thickness of 80m and ore thickness of 50 m , then the stripping ratio will be: 80/50= 1.6
Can standard deviation be a measure of precision?
Yes SD is ofcourse measure of precision
What is a non resistant measure in statistics?
The mean is called a non-resistant measure in statistics.
Which measure of central tendency can be calculated for both quantitative data and for qualitative data?
Mode is the only measure of central tendency to measure quantitative dataor qualitative data.
What is throat of fillet weld?
A fillet weld is a triangular weld with sides of a width, w by w . The throat is the thinnest portion, which is w divided by square root of 2. The throat thickness is used in stress calculations
What is the ratio between the leg length and the throat thickness on a mitre filet weld with equal leg lengths?
it depends on the fillet welds dimentions and fit up requirements
How do you measure filet weld?
In a fillet weld, the leg and size are the same for the convex weld.
Butt-weld and grrove weld?
First, Butt-weld is short for a butt groove. Welding in a butt-groove starts at the throat of the butt-groove. The first weld point could be a tack-weld: holding the two materials to be welded together. The throat is measured and filler metal and electrode are determined to create the root pass.
How long does it take a human to weld a 1 foot fillet weld?
It depends on the thickness and type of materials being welded.
What is the rope thickness unit of measure?
its thickness can be measure in mm(milimeters)
What would you measure of unit would you measure a thickness a?
What measure of units would you use to measure the thickness of a phone book
What thickness steel can a 90 amp welder weld?
about 2mm mild steel max
How do you measure the thickness of a pencil?
There are many ways in which you could measure the thickness of a pencil. You could use a string to measure it.
How do you measure thickness in ndt?
The best way to measure thickness is to use an ultrasonic transducer. You use the back reflection to figure out the thickness.
How do you measure penetration in welding?
To measure penetration of a weld, one must cut and etch the weld, preferably on a test coupon. Etching is just using an acid that will discolor the weld metal so that there is a visible difference between the weld metal and the base metal. Once the acid has taken affect, one can measure the weld using calipers or a similar measuring device.
What unit of measure is paper thickness measured in?
An instrument called micrometer is used to measure paper or card thickness.
