Investigation of Microstructure weld zone of Hastelloy X Pulsed Nd-YAG laser welds
In the present study, the microstructure of welded zone of Hastelloy X sheets with thickness of 1 mm via pulsed Nd-YAG laser welding were studied. This welding process was done by autogenus and conductive method. Microstructure were observed by metallurgical OM and SEM. Results shown Solidification of the weld metal is dendritic. The dendrites in the central zone of the welding are fine and equ...
متن کاملConditions for effective Nd - YAG laser angioplasty HERBERT
To establish the optimal conditions for recanalisation of obstructed arteries without damage to vessel walls, a Nd-YAG laser coupled to a 0.2 mm diameter optic fibre was used on obstructed human cadaver coronary and peripheral arteries and on popliteal arteries in amputated limbs. Vaporisation of atheromatous plaques was consistently obtained with an energy of 360-600 J and a diluted blood perf...
متن کاملInfluence of shielding gas composition on weld structure in pulsed Nd: YAG laser welding
This work studied the effect of additions of carbon dioxide to argon shielding gas on the weld shape and microstructure of ST14 steel in pulsed Nd: YAG laser welding. By additions of carbon dioxide up to 15%,the weld area and depth/width ratio decreases while rising of carbon dioxide up to 25% causes increasing of weld area and depth/width ratio. It is observed that the weld metal microstructur...
متن کاملبررسی و مقایسه اثر q-switched nd yag laser و erbium laser در درمان ضایعات پیگمانته
هدف: این مطالعه به منظور بررسی و مقایسه اثر q-switched nd yag laser و erbium laser در درمان ضایعات پیگمانته انجام شده است. روش مطالعه: 116 فرد مبتلا به ضایعات پیگمانته از نوع فرکل و خال وارد مطالعه شدند که 58 مورد با استفاده از q-switched nd yag laser و 58 مورد با لیزر erbium درمان شدند و در نهایت میزان اثربخشی (از بین رفتن کامل ضایعات) در دو گروه تعیین و مقایسه گردید. یافته ها: در این مطالعه...
15 صفحه اولNd-YAG Laser Treatment of Pilonidal Cysts
A 38 year-old girl with a recurrent suppurative pilonidal cyst was successfully treated causally with an Nd-YAG laser, and with no recurrence at the 3-month follow-up. A similar success is observed for another 15 consecutively treated patients, including suppurative cases. The effect could be attributable to the ability of the YAG-laser to operate at a wave-length of 1064 nm and to penetrate th...
