How Water Based Corrosion Inhibitors Can Protect Welded Parts

A water soluble corrosion inhibitor, also called an anti-coated coating or a rust inhibitor, is a compound that contains a small amount of corrosion-fighting minerals like iron and tin. These compounds are used in a variety of industries to protect certain types of metal surfaces from damage due to water-borne corrosion. In fact, they are one of the most commonly used corrosion inhibitors. Their cost effectiveness makes them practical for a wide variety of applications in all kinds of industries including the automotive, marine, and construction industries.

Two distinct varieties of water soluble corrosion inhibitors have been developed: the new water based corrosion inhibitor (usually known as WSCI) and the oil based water soluble corrosion inhibitor (also called HPI). New HPI products provide greater protection against the effects of water at very high temperatures than the older versions of these products. Both of these products have distinct advantages, and often are employed in different applications depending on their suitability. Some examples of common uses include:

Most of the new corrosion inhibitors available are designed to resist the effects of various metals at very high temperatures. The most common type of anti-corrosion agent used in high temperature anti-corrosion applications is the oil soluble corrosion inhibitor (or PCI). This particular type of compound was originally developed for use in the aerospace industry because it had the unique ability to resist the effects of both heat and mechanical stress at very high temperatures. The ability to resist the stresses to a certain degree, combined with the ability to diffuse heat throughout the entire surface, makes this type of anti-corrosion agent very effective at combating the corrosion of metallic parts at very high temperatures.

Another very popular type of water soluble corrosion inhibitor product applications involves the use of anti-corrosion additives. As its name suggests, these additives can work to prevent the corrosion of any type of metal when that metal is exposed to an acid or alkali concentration. Common examples of these types of additives would be the alkali metals such as the stainless steel, the copper, and the brass. These additives can provide the necessary coating for a metal to have a longer lifespan when being exposed to high temperatures.

A third very popular type of water soluble inhibitor is the magnetic additives. These additives are typically used by many metalworking shops to protect the pieces they are working on from becoming pitted or discolored from the contact with an abrasive metal. This protection can be quite valuable to a metal working shop as the prevention of pitting the material would allow the worker to continue working with the piece. Some examples of these highly effective additives would be the boron and silicon hydride. Although the cost of the magnets will add up over time, the highly effective nature of the compounds will ensure that they will be well worth the cost.

There are many other types of water based corrosion inhibitors. Most of these have been developed to resist corrosion at various temperatures between approximately -50 degrees and 500 degrees Fahrenheit. These different types of inhibitors are available in several different concentrations to meet the varying needs of the metalworking shop or individual. It is important to remember that each type of inhibitor will work at a different temperature and to properly mix these water based corrosion inhibitors to an appropriate strength. This will ensure the proper coating on the metal and help to keep it protected from any potential damage caused during the welding process.
