In computing the term pixels is actually a short for picture element. It refers to a single point (a dot) in an image. Computer monitors display images by dividing the screen into several pixels (dots) which are arranged in an x,y axis (rows and columns). The arrangement of the dots are so close to each other that they will appear as though the are connected.
It is important to note that on color monitors (which are by far the commonest), every pixel is made of three dots (red, blue and green) otherwise called the RBG all converging at same point.
The smallest v groove angle that can be welded using the FCA welding process is 20 degrees. Double v joints help for buckling forces especially in welding thicker metals.
