CWB level 1 exam prep When using measuring devices, accuracy is how: close repeated measurements are to the true value. True or False? Systematic errors can always be avoided by using a sufficiently precise measuring instrument. False Brainpower Read More Dimensions on a drawing should be measured from a common datum or reference line to avoid: cumulative errors True or False? When reading a meter with a pointer, always stand directly in front to avoid a parallax error True When making accurate measurements with a long steel tape, it is important that the tape be held: under the correct tension applied with a tension handle Vertical referance lines are easily checked using a __________________________________ Plumb line True or False? The standard recognized temperature for checking steel tapes is 20 degrees C. True True or False? When using a string as a reference line to measure distortion in a plate, always make the measurements horizontally from the string to the plate. True True or False/ Tapered wedges are used for measuring the inside and outside edge of a gap. False According to CSA Standard W59, at what distance from the weld must the minimum preheat be maintained in a 44 mm thick plate? 75 mm Visual inspection of inaccessible areas may be carried out with the use of: boroscopes. CSA W59 states surfaces and edges that are to be welded must be free of slag, rust, paint and so forth within _____________________ of the weld to prevent weld contamination> 50 mm There is a cost to poor fit-up since a gap of ________________ mm or greater in a fillet weld requires the size of fillet weld to be increased by the amount of the gap> 2 ____________________ are normally required to be welded together to avoid a gap that may initiate cracks. Backing bars Which dimension should be measure when visually inspecting a concave fillet weld? The throat For fillet welds with unequal leg sizes, where an equal leg fillet was specified, always measure the: shorter leg length True or False? There is a simple relation between face width and throat size for flare welds that can be used in all cases. false According to CSA W59, the maximum allowable depth of undercut for a weld cyclic loading where the direction of load is transverse to the undercut is: 0.25 mm True or False? In CSA Standard W59, the acceptable porosity requirements are different for static and cyclic loading.
