…Stress concentration depends on the local weld geometry which in turn depends on such factors as the welding process, the welding position and the type and extent of any welding flaws. (W 16) (1)

Welding position = Posição de soldagem

Laser cutting trials for a given laser power, gas pressure and cutting speed, were performed by traversing the laser beam across the tube in a straight line, while maintaining the focal position along the centre of the tube.(W 84) (2)

Focal position = Posição focal

Whilst individual swirls showed broadly comparable features, each was relatively unique due to slight variations in geometry, dissolution and chemistry. In comparison, the mid-bead position of the interface was quite reproducible. (W 130) (3)

Mid-bead position = Posição mediana
