Application and Development of Nickel Alloy in Aviation Field


R.F.Smith of the United Kingdom discussed the development of four aspects of nickel alloys recently used in aviation, the first is the disk alloy; the second is the low expansion superalloy; the third is the superplastically formable nickel-based superalloy (Inconel718 alloy); the fourth It is a low expansion alloy (Nilo) for composite preparation tools.


Common sense of storage of welding consumables


(1) For electrode storage, pay attention to the ventilation and dryness of the warehouse. The relative humidity of the air should be controlled below 60%. When stacking, keep a distance of 30cm from the ground and the wall.


Basic principles of welding consumables selection


Consider physical properties, mechanical properties and chemical composition of weldment materials


Nickel-based electrodes, are domestic brands really worse than foreign ones? Someone did a test comparison


Our company is a petrochemical and coal chemical construction unit. The main welding methods include electrode arc welding, argon arc welding, MIG welding and submerged arc welding. The main welding materials are also around the selection of electrodes and wires for these welding methods.


Although the tungsten market is delicate, there are still expectations


The summer vacation is coming to an end, and inquiries from Europe are occasionally heard. However, due to the domestic tungsten price has experienced a fall and stabilized, the inquiries from the external market are mostly inquiries and wait-and-see.
