In welding, zinc melts into a liquid and floats

In welding, zinc melts into a liquid and floats on the surface of the molten pool or at the root of the weld. At the same time, zinc and iron can form brittle compounds between metals, these brittle phases reduce the plasticity of the weld metal, and produce cracks under the action of tensile stress. Generally, low-carbon steel is generally used because of its ease of operation. It will also drop the welds brittle and the rigidity. In the case of fillet welds, the zinc layer is also melted as much as possible in the first layer and vaporized and evaporated to escape wholesale 2343 steel Factory the weld. Zinc has greater solid solubility in iron, zinc liquid will deeply etch the weld metal along the grain boundary, and low melting point zinc forms "liquid metal embrittlement".

The seam must be polished before welding, otherwise will have bubbles, trachoma, false welding, etc. In the case of horizontal and vertical welding, if the short slag electrode such as J427 is used, the tendency of undercut will be very small; if the front and back reciprocating bar technology is used, the defect-free welding quality can be obtained. When the zinc layer is made After melting, return to the original position to continue welding.  Characteristics of welding galvanized steelUsually galvanized steel coated with zinc on the low carbon steel, and the galvanized layer is about 20um thick.With the development of the economy, the demand of galvanized steel pipes increasing day by day. In order to weld well, the groove size should be around 60 ~ 65 °, gap should be 1. But most of people may not know the precautions for welding galvanized pipes. The melting point of zinc is around 419 ° C and the boiling point is around 908 ° C.5mm.. How to control the process of welding galvanized steel?The preparation of galvanized steel before welding is the same as the low carbon steel. In the work operation, do centralized beveling with out blunt edge which is used for centralized control. The electrode should be selected according to the base material of the galvanized pipe.

The method is to move the end of the electrode forward about 5 ~ 7mm. Welding method: When welding the first layer of multi-layer welding, try to melt the zinc layer and vaporize and evaporate it to escape the weld, which can reduce the liquid zinc remaining in the weld.5 ~ 2. The two-layer welding process reduces the possibility of under-welding

Kidney or heart problems, use of steroids

Kidney or heart problems, use of steroids as wholesale 2343 steel well as other conditions are the reasons that cause water retention which create puffiness under eyes. Else you may place a chilled, steeped chamomile or a green tea bag over each eye. The other reasons for puffy eyes can be ingesting too much salt or perhaps a high intake of alcohol. A minimal incision is made inside the lower eyelid by surgeons in order to remove the sagging fat pad causing puffiness.The main reasons for under eye puffiness is basically due to fluid and fat. The extra skin around the eyelid can also be vaporized by using laser treatment.

Foods which are high in saturated fat should be avoided in order to control under eye puffiness. The best way to take care of puffy eyes is rinse your face with cold water as soon as you wake up.One of the best way is to apply dark circles cream under your eyes for some time. Continue doing this until you see improvement. Puffiness is a result of a fat pad which cushions the eye pulling away from the bone of the lower eye and sagging due to age. Also, under eye puffiness indicates that the pillow you're sleeping on is too flat. The rest of the cucumber can be peeled and pureed in order to be applied as a pack on your face. Retaining water also causes bags under eyes, especially in the morning.In case you wish to know how to get rid of bags under eye, the clear cause is that you're probably not able to get enough water in your system. Heredity can also be a cause for some people. This will help to seal in water.The under eye puffiness caused by fat requires cosmetic surgery in order to remove the fat pad.

Thus you should drink plenty of water. Place two slices of cucumber over your eyes.Cucumber has anti-inflammatory properties which can reduce redness as well as the puffiness of eyes. This will constrict blood vessels in order to reduce swelling. There are many ways to get rid of under eye puffiness.
