Metal welding

Firmetal, 2018-06-13 10:00:00 PM

General welding and brazing (brazing) and soft soldering (soldering) the difference between soft brazing melting by lower melting point (below the melting point of workpiece itself) to form solder connection, without heating melting the artifact itself.
There are many sources of energy for welding, including gas flame, arc, laser, electron beam, friction and ultrasonic wave. In addition to being used in factories, welding can be done in a variety of environments, such as fields, underwater and space. No matter where it is, welding may bring danger to the operator, so proper protective measures must be taken in welding. The possible injuries caused by welding include burns, electrocution, visual impairment, inhalation of toxic gases, and excessive exposure to ultraviolet rays.

Nickel rhenium alloy

Firmetal, 2018-06-07 09:20:00 PM

Rhenium can increase the creep strength of nickel-high temperature alloys, which can be used to make combustion Chambers, turbine blades and exhaust nozzles for jet engines. Rhenium nickel alloy is the core material of modern jet engine blade, turbine disc and other important structural parts. The use of rhenium can improve the performance of nickel-based high temperature alloys. Alloys can also be made for single crystal blades. Both of these functions allow turbines, especially high-pressure ones, to operate at higher temperatures. In this way, the designers can increase the pressure on the turbine and improve the operating efficiency. Or the engine could speed up fuel combustion and generate more thrust. In addition, the operating temperature can be kept low and the difference between the actual operating temperature and the maximum allowable temperature of the turbine can be increased, thus extending the service life. People can also consider both aspects of the engine and improve the performance and durability of the engine.
