Synergic control in MIG welding and penetration control in TIG welding
… or modulated with any waveform to achieve ‘thermal pulsing’. In addition, two approaches have been used to adapt the synergic control units to a lower cost, thyristor controlled power source which is more widely used in industry. In one approach, the generalised control equation used …

Sources of thermally generated vacancies in single-crystal and polycrystalline gold
… studied and least understood. The electrical pulsing work of Jackson (1960), Lund (1964) and Koehler (1960, 1964) pioneered the study of vacan¬cy generation at high temperatures, when a lattice is subjected to a sudden and large subsaturation of vacancies. Their experiments indicated that …
