چکیده
It is proposed to consider the device of an integrated ventilation system that combines local exhaust welders' workplaces and general premises as main direction normalizing parameters air environment when performing arc welding. When organizing welding rooms limited dimensions, it necessary have possible effect drift flows. increases a result joint operation devices. The effectiveness devices for posts analyzed. depends on space-planning solutions, relative position supply devices, well peculiarities technological operations. For specific example room, optimal variant organization stations found. fields mobility, its temperature concentration harmful impurities been calculated by computer modeling. factors influencing efficiency are revealed combinations providing maximum permissible emissions in working zones welders established. conditions determined under which exchange suction sufficient maintain room at MPC level. results obtained can be used develop engineering methods calculating optimizing systems, analyze structural design solutions electric industries. Investigations processes propagation aerosols production area carried out means experimental measurements, simulation using Ansys Fluent software hydrodynamic package.

ترجمه متون ادبی در دنیای امروز از اهمیت ویژه ای برخوردار است. فرهنگ های مختلف با استفاده از متون ادبی ملل و فرهنگ های دیگر سعی در غنی کردن فرهنگ و ادبیات کشور خود دارند. کشور ما نیز از این قاعده مستثنی نیست. در ایران، ترجمه متون ادبی اروپائی که با دوران مشروطه ایرانی آغاز می شود موجب تغییرات اساسی در فرهنگ، شیوه زندگی و تفکر ایرانیان شده است. در این دوران نه تنها در امورات سیاسی و فکری کشور تغی...
15 صفحه اولGas tungsten arc welding
Gas tungsten arc welding (GTAW), also known as tungsten inert gas (TIG) welding, is an arc welding process that uses a nonconsumable tungsten electrode to produce the weld. The weld area is protected from atmospheric contamination by a shielding gas (usually an inert gas such as argon), and a filler metal is normally used, though some welds, known as autogenous welds, do not require it. A const...
متن کاملModelling of Electrode-arc Coupling in Electric Arc Welding
Modelling of the arc in electric arc welding is significant to achieve a better process understanding, thus gain better weld quality and a more efficient production process. It requires knowing the conditions at the surfaces of the anode and cathode. These conditions are very difficult to set from measurements and should be calculated. This requires modelling the complex physics of the electrod...
