(metallurgy)
In certain types of welding operations, controlled reduction of the welding impulse over a predetermined time interval to prevent rapid cooling of the weld nugget.

The Type I current onset was characterized by two phases: a relatively fast sigmoidal phase and a very slow latter phase, whereas the current decay seemed to consist solely of a relatively fast phase (Fig.
Numerous authors [4-17] associate the current decay down a long-wire antenna as being due to radiation.
The cells studied presented similar behaviors, in which the film with 5% of [Nb.sub.2][O.sub.5] presented a lower current decay, being that the current density value at the beginning (60 s) was off 1.2 mA.[cm.sup.-2] to both the films and after 600 s the containing cell 15% of [Nb.sub.2][O.sub.5] presented current density of 0.75 mA.[cm.sup.-2] and the film with 5% of [Nb.sub.2][O.sub.5], j = 0.86 mA.[cm.sup.-2].
In the decay transient analysis, a characteristic time constant [t.sub.D] is determined using the slope of current decay after the steady state.
Even at the national level the cultural debates/acts, in general, focus more on our 'great' ancient past than on reviewing the current decay.
In our analysis we chose the [v.sup.*] [right arrow] eW mode because of the high branching ratio of the charged current decay channel.
The magnetization characteristics of SG can be determined by current decay tests carried out both along the longitudinal axis (d) and the transversal axis (q).
The relationship curve between the ripple current decay of switch frequency and r is as shown in Fig.
Figure 4(b) shows a magnification of the photo current decay immediately after letting air into the chamber.
Long-term poisoning rates ([delta]) were evaluated from the record of current decay (Figure 5) at times greater than 500 s using the following equation [20]:
America might not be facing complete collapse, a la Rome, but Luce's narrative makes it clear that tremendous effort -- and plenty of luck -- will be needed to reverse its current decay.
HXT accelerated current decay, caused a left-shift in steady-state inactivation curve but had no effect on voltage-dependence of activation.
