Galvanizing Hot Dip Galvanizing Process , Dipping Process Steel Protection from Rust Prevention What is Galvanizing ? What is hot dip galvanizing process ? Galvanising is the process of applying a coating of zinc to steel, in order to protect it against corrosion. The most common method used for the majority of sizes of steel members or fabrications is hot dip galvanising which involves the entire immersion of the steel product into a bath of molten zinc hot-dip galvanizing & COLD Galvanizing of MILD STEEL 1: How does galvanizing protect steel from corrosion ? Zinc metal used in the galvanizing process provides an impervious barrier between the steel substrate and corrosive elements in the atmosphere. It does not allow moisture and corrosive chlorides and sulfides to attack the steel. Zinc is more importantly anodic to steel . This means it will corrode before the steel, until the zinc is entirely consumed. 2. What are the steps in the galvanizing process ? There are four steps: Pre-inspection – where the fabricated structural steel is viewed to ensure it has, if necessary, the proper venting and draining holes, overall design parameters which are necessary to yield a quality galvanized coating Cleaning – steel is immersed in a caustic solution ( Degreasing Solution ) to remove oil. Grease, dust and dirt, This is followed by dipping in an acid bath (hydrochloric) to remove mill scale, rust, & finally dipped in bath of flux that promotes zinc & steel reaction, retards further oxidation (steel will not react with zinc unless it is perfectly clean) Galvanizing – the clean steel is dipped into a kettle containing 4500C molten zinc where the steel. zinc metallurgically reacts to form three zinc-iron inter-metallic layers and one pure zinc layer Final inspection – the newly galvanized steel is sight-inspected, followed up by measurement of coating thickness with a magnetic thickness gauge 3. How does the cost of hot-dip galvanizing compare to other corrosion protection systems, such as paints? When compared with paint systems, hot-dip galvanizing after fabrication has comparable initial application costs. In fact, the lower life-cycle costs of a hot-dip galvanized project makes galvanizing the smart choice for future. 4. How long can I expect my galvanized steel project to last in service ? Hot-dip galvanized steel resists corrosion in numerous environments extremely well. It is not uncommon for galvanized steel to last more than 70 years under certain conditions. 5. Does the galvanized steel coating of zinc resist abrasion ? The three intermetallic layers that formed by Fusion Bonding between IRON and ZINC Metals during the galvanizing process are all harder than the substrate steel and have excellent abrasion resistance. 6. What causes wet storage stain and how can it be prevented ? Zinc on newly galvanized steel is very reactive and wants to form zinc oxide and zinc hydroxide corrosion products on exposure to Air, UV Radiation and moisture and Water vapours in the atmosphere. This eventually become the stable zinc carbonate. When galvanized steel is tightly stacked or stored in wet boxes that don’t allow for free flowing air, the zinc forms excessive layers of zinc hydroxide, otherwise known as wet storage stain. Most wet storage stain can be easily removed with a cleaner or nylon brush. To prevent wet storage stain, store galvanized steel indoors or block it so that there is ample free flowing air between each galvanized article. .................................................................................................................

Easy Nickel And Copper Electroplating Method
Simple, cheap, and reliable way to plate metals. I used this method to plate the screens in my Edison Battery... Check my page at: http://www.noonco.com/nickel/ For FAQs and less expensive alternatives. Just in: I see that Amazon has Nickel Ammonium Sulfate for only $21 for 100 grams. The address I found was: http://www.amazon.com/Ammonium-Sulfate-Laboratory-Hazardous-Chemical/dp/B008V5ZFB0/ref=sr_1_3?ie=UTF8&qid=1390583233&sr=8-3&keywords=nickel+ammonium+sulfate SPECIAL NOTE: A lot of viewers have written to say that the MSDS lists nickel salts as carcinogenic, but I have not had a high degree on concern because I also see many other common items listed as similar carcinogenic risks. These include Diesel exhaust, gasoline, paint fumes, plastic glue, lighter fluid, lead and many others. So I believe with care, most of these can be handled safely. Please be cautious and respectful of any chemical. It's not worth it to get hurt. 3 G's: Goggles, gloves and good ventilation... P.S. After many suggestions that I experiment with less expensive Nickel Sulfate, I've found a less expensive chemical combo that also makes a fantastic and shiny coat! I have this up for you at www.noonco.com/nickel Thought I'd pass it on. :-) P.S. For those interested in the Edison Battery, check out my pages at: http://www.noonco.com/edison/

Cladding (metalworking)
Cladding is the bonding together of dissimilar metals. It is different from fusion welding or gluing as a method to fasten the metals together. Cladding is often achieved by extruding two metals through a die as well as pressing or rolling sheets together under high pressure. The United States Mint uses cladding to manufacture coins from different metals. This allows a cheaper metal to be used as a filler. This video is targeted to blind users.

Cathodic protection
Cathodic Protection (CP) is a technique used to control the corrosion of a metal surface by making it the cathode of an electrochemical cell. A simple method of protection connects protected metal to a more easily corroded "sacrificial metal" to act as the anode. The sacrificial metal then corrodes instead of the protected metal. For structures such as long pipelines, where passive galvanic cathodic protection is not adequate, an external DC electrical power source is used to provide sufficient current. Cathodic protection systems protect a wide range of metallic structures in various environments. Common applications are: steel water or fuel pipelines and storage tanks such as home water heaters; steel piers piles; ship and boat hulls; offshore oil platforms and onshore oil well casings; and metal reinforcement bars in concrete buildings and structures. Another common application is in galvanized steel, in which a sacrificial coating of zinc on steel parts protects them from rust. This video is targeted to blind users.

This project should only be attempted with adequate knowledge and training, proper protective safety gear, and in a fire resistant area with adequate ventilation. The sparks flying from the foundry can ignite fires, and the fumes from burning dross can be toxic. Use caution and common sense. Be safe and have fun, but always remember that any project or experiment is at your own risk. Music By: Jens Kiilstofte - “Morning Cruise” https://machinimasound.com/music/morning-cruise Project Inspired By: This project was inspired by 2 videos. If you check them out, please let them know that Grant Thompson sent you. Thanks! :) First was a “lost foam casting” tutorial by “The Art of Weapons” (http://bit.ly/IBRamboneSlingshot) and a Rubber Band gun designed by “RBGuns” (http://bit.ly/IBM9RubberBandGun). I modified the template from RBGuns to make the styrofoam mold. Project History & More Info: The gun is solid aluminum, made from melted down soda cans. I spent over 100 hours of time, and 7 styrofoam prototypes to make this video. About a third of the time was spent filing and sanding the gun. Each time I poured a casting for the gun, the trigger guard wouldn’t complete all the way through, so I kept making new styrofoam guns, modifying the designs slightly until it worked. Once I got a fairly clean casting, I put 2 days into filing down rough points, and sanding them smooth. The gun could use a little more work, and it’s not perfect, but this experiment was mainly a proof of concept that nearly anything you can imagine can be made fairly easily with the “lost foam casting” technique. Overall, I really am happy with the gun though! It weighs 556 grams, and is really quite smooth to feel. For future projects, I plan to work more with green sand casting. I believe it will leave a nicer finish overall and won’t require as many prototypes to get it right :) Instead of foam, wood plugs can be used to make the molds, or even real weapons for that matter.

Pickling (metal)
Pickling is a metal surface treatment used to remove impurities, such as stains, inorganic contaminants, rust or scale from ferrous metals, copper, precious metals and aluminum alloys. A solution called pickle liquor, which contains strong acids, is used to remove the surface impurities. It is commonly used to descale or clean steel in various steelmaking processes.

Oxy-fuel welding and cutting
Oxy-fuel welding (commonly called oxyacetylene welding, oxy welding, or gas welding in the U.S.) and oxy-fuel cutting are processes that use fuel gases and oxygen to weld and cut metals, respectively. French engineers Edmond Fouché and Charles Picard became the first to develop oxygen-acetylene welding in 1903. Pure oxygen, instead of air, is used to increase the flame temperature to allow localized melting of the workpiece material (e.g. steel) in a room environment. A common propane/air flame burns at about 2,000 °C (3,630 °F), a propane/oxygen flame burns at about 2,500 °C (4,530 °F), and an acetylene/oxygen flame burns at about 3,500 °C (6,330 °F). Oxy-fuel is one of the oldest welding processes, besides forge welding. Still used in industry, in recent decades it has been less widely utilized in industrial applications as other specifically devised technologies have been adopted. It is still widely used for welding pipes and tubes, as well as repair work. It is also frequently well-suited, and favored, for fabricating some types of metal-based artwork. As well, oxy-fuel has an advantage over electric welding and cutting processes in situations where accessing electricity (e.g., via an extension cord or portable generator) would present difficulties; it is more self-contained, in this sense — hence "more portable".

Reinforced concrete
Reinforced concrete is a composite material in which concrete's relatively low tensile strength and ductility are counteracted by the inclusion of reinforcement having higher tensile strength and/or ductility. The reinforcement is usually, though not necessarily, steel reinforcing bars (rebar) and is usually embedded passively in the concrete before the concrete sets. Reinforcing schemes are generally designed to resist tensile stresses in particular regions of the concrete that might cause unacceptable cracking and/or structural failure. Modern reinforced concrete can contain varied reinforcing materials made of steel, polymers or alternate composite material in conjunction with rebar or not. Reinforced concrete may also be permanently stressed (in compression), so as to improve the behaviour of the final structure under working loads. In the United States, the most common methods of doing this are known as pre-tensioning and post-tensioning. For a strong, ductile and durable construction the reinforcement needs to have the following properties at least: This video is targeted to blind users.
