The greatest deviation from the average crack length is usually the measurement closest to the outside surfaces of the specimen, furthest from the centre of the pre-crack. (W 7) (1)

Crack length = Comprimento da rachadura                                                 

The system used in this work is unusual in that its focusing lens had a long focal length of 500mm. The effect of this was to produce a very narrow beam of light, with a large depth of focus. (W 90) (2)

Focal length = Comprimento focal

The voltage was determined by the programme and for pulsed welding the setting is the voltage during the pulse, because this is used to control arc length. (W 55) (3)

Arc length = Comprimento do arco
