Welding With Alloy 20? Use These Pointers To Be Successful

Posted by on Mar 7, 2016 in Uncategorized |

Alloy 20, primarily made up of nickel but containing iron, chromium, molybdenum and copper, is a metal that can be used for a variety of industrial purposes because of its ability to resist a number of acids. If you are welding with this metal, however, stay aware of the following pointers so that your weld turns out well. Add Helium Gas If you are like many welders and plan to use tungsten arc welding for your project, your first thought may be to tackle the weld with argon gas. However, it is important to note that, as a nickel alloy, Alloy 20 doesn’t conduct heat very well. Argon may be unable to cut through the alloy or may take much longer than other gases, such as helium, which heat up more quickly.  For better results, it’s a good idea to use a mixture of helium and argon gases to cut through the alloy. The combination will allow you to get a sharper weld point on the piece you’re working on. Avoid a Small Gas Lens It is a good idea to avoid small gas lenses while you work with this alloy. With a large lens, you will be better able to control the immediate environment around the weld point, ensuring that the gas will constantly flow, which can keep out contaminants and help you avoid air pockets. Because the weld is purer, you can worry less about how the weld will perform over time.  Keep Weld Current Low Even if you are using a helium/argon mix on your weld, because the alloy is so thick, you might be tempted to turn up the temperature to get through it quickly. However, if you do that, you run the risk of causing the entire pipe to weaken. That’s because as the metals melt and turn to liquid, heat that is too high may even cause some of the liquid metals to evaporate. Because in that case the pipe no longer has the same chemical makeup, it is weaker than other portions of pipe. As a result, the pipe might be more likely to rust or buckle. Instead, make a conscious decision to keep the tungsten temperature low as you weld. Patience will give you good results and preserve the integrity of the pipe.  With the pointers in this article, you can be more confident about welding with Alloy 20. If you need assistance, talk to an expert (such as one from Tiger Metals, Inc.) who can help you with your...

Choosing A Blasting Medium For Your Abrasive Blaster

Posted by on Mar 4, 2016 in Uncategorized |

It was not so very long ago when abrasive blasting was simply known as sandblasting, as if the only choice of blasting medium was sand. Experimentation has shown that your choice of blasting medium can have an important impact on the results of your blasting job. For example, if you use sand to blast away paint coating a delicate instrument, the sand can pit the material the instrument is made from or otherwise damage it. Thus, you need to stock several different mediums to ensure you remove the paint that needs to be removed without damaging the object you are trying to reclaim.  Walnut Shells It might sound like a gimmick, but walnut shells have a place in your repair shop. If you use a highly abrasive blasting medium, you will strip away all of the coats of paint on an object. This then requires you to replace not only the topcoat but also the underlying coats. These undercoats can be just as expensive as the topcoat, and unlike the topcoat, they might not be in need of replacement. Using walnut shells, you can blast away the topcoat without damaging the undercoats. This will save you time and money in that you only have to apply a topcoat to get whatever object you are repairing back into its ideal condition.  Choosing Your Medium According to Your Purpose While blasting is an excellent way to strip away rust, damaged paint, stains, and other damage to an object that you are trying to restore, not every job requires stripping an item. In some cases, all you need to do is clean up an object. For example, if you have stuck-on grime such as tar or resins that you can’t remove with a pressure washer, you should be able to blast away the grime with the right blasting media. While abrasives such as aluminum oxide are ideal for your stripping tasks, they would be the wrong choice for cleaning. Instead, you should consider a softer medium such as corn cob.  Companies that manufacturer blasting abrasives are always experimenting with new materials that can be used to accomplish different tasks. Not only does this increase the demand for their blasting equipment, but it allows you to use your equipment in new ways. If you are in the business of making old, dirty, or otherwise damaged equipment look new, then a good stock of blasting abrasives is just what you need to expand your ability to take on new jobs.  Contact companies like Steel Coatings Inc for more...

Why You Should Hire A Fabrication Company For Your Metal Fence

Posted by on Mar 3, 2016 in Uncategorized |

If you are excited about welding your own metal fence to give it a unique look and add more character to your house, you might want to opt for professional assistance instead. You don’t have to do the welding on your own and risk getting injured, as a fabrication company can create a fence that is based on your design. Take a look at the list of reasons below to discover why hiring a fabrication company is the best route to take for customizing a metal fence. 1. You Can Avoid Buying Welding Equipment If you don’t have welding equipment already, it is wise to seek help from a fabrication company for your metal fence project. You will have to buy multiple pieces of equipment and safety supplies in order to accomplish the task on your own. Besides the arc for bonding metal pieces together, you might also need a downdraft table and exhaust fan to safely work on the project. You risk getting injured from manganese or welder’s flash if you don’t have the right safety equipment. Don’t end up having to spend a lot of money on equipment that you don’t intend on using on a regular basis. 2. The Fence Design Will Be More Precise The skills of professional fabricators can be helpful when you want a fence design that has a lot of curves and other shapes to achieve the unique look that you want. The fabricators will not only be able to cut each piece of metal with precision with a lathe machine, but computerized equipment can also be used to accomplish the task with the precise cutting of lasers. Even if you were to invest in your own lathe machine and computerized equipment, your cuts may not be precise if you don’t have the right kind of welding experience. 3. More Than Welding Can Be Done Hiring a fabrication company is ideal because they can make the finished metal fence look more appealing than you can. Rather than just painting the metal, professional fabricators can also give the fence a shiny look or make it look dull. The texture of the metal can have a big effect on how good the fence will look with paint on it. You can even opt for getting a powder coating on the fence to make the color last longer, as it will be baked into the metal. Contact a fabrication company, such as Suburban Welding & Steel LLC, and discuss your metal fence ideas so professionals can do the...

How Enzymes And Grease Traps Can Protect Your Septic Tank

Posted by on Mar 2, 2016 in Uncategorized |

One of the hardest products on your septic tank is grease. Grease can easily be introduced to your tank by pouring leftover grease down the drain when cooking and when using a garbage disposal. The best way to stop grease is to not pour it down the drain in the first place. However, a grease trap and special enzymes are also helpful when keeping your septic tank clear of grease. The Worst Sources Of Grease Grease comes from various food products, including meats, cooking oils, lard, butter, shortening, sauces and baked goods. Rather than stopping grease, a garbage disposal simply breaks the grease up and allows it to reach the septic tank. Given that grease is lighter than water, it floats on the top. It can also combine with the solids, toilet paper, and soap residue to form a hard crust. This then flows into the drain field, where it will then cause the septic tank to back up. How Enzymes Can Help Enzymes added to a septic tank attack the grease by destroying the connections between its individual molecules. Once this happens, the molecules will have no way to join together and form grease deposits. Enzymes will not eliminate all of the grease, though they can eliminate enough to make a difference. However much the enzymes eliminate depends on the temperature and pH. The enzymes can be added by simply pouring them down the drain or toilet. When You Should Get A Grease Trap Grease traps are usually not used in homes because the average household does not produce enough grease to justify one. However, if you like to fry donuts or if your cooking habits lead to you pouring a lot of grease down the drain, the grease wouldn’t be mixed well enough with dish detergent to mitigate the risk. A home will usually need the smallest grease trap available. Grease traps are installed either under the sink or outside the home. How To Install The Trap How the grease trap is installed depends on the particular model. There are usually three connections, with one connection attached to the holding tank vent, one connected to the sink that will be the source of the grease and one connected to the pipe that travels to the septic tank. The last connection is on the lower right of the grease trap. Even if you have a grease trap, make sure that you do not flush solids down the drain. Click here for more...

Accentuate Your Nuptials With A Touch Of Concrete

Posted by on Mar 2, 2016 in Uncategorized |

Concrete has become quite a hot trend in the past few years. In fact, a random Google search of the word “concrete’ can get you approximately 364 million hits and counting. At a cost of between $3.25 and $5.25 and with the flexibility to be used in a variety of ways, concrete can be incorporated in almost any project or event that you are planning – including your wedding. Of course, it can be used in the flooring, walls and ceilings as well tabletops, garden pathways and furniture to help give your wedding that rustic feel. However, concrete has so much more potential in the ways that it can be used both before and during your celebration. So, if you are among the 2.3 million couples who are expected to tie the knot this year and you are looking for some unique accents to make your wedding extra special, here are a few concrete ideas for you.  You are invited Consider for a moment the possibility of concrete invitations. While this idea is a bit unusual, it can be done as either a DIY project to custom make your invitations or you might be able to find a wedding invitation designer who is game enough to assist you. Whichever you choose, you should ensure that they are ready at least 10 to 12 weeks before the wedding. To get this done, you will need letterpress plates to create the molds which will be used to imprint each concrete invitation.  Since they are breakable, invitations to those who are far away may need to be bubble wrapped and express delivered. The others might probably be best hand delivered to ensure their safety. With this ring While most people will want to go with the traditional gold, silver and diamonds, an option that is available is that of steel and concrete rings. While this is probably a good idea for the groom, the agreeable bride can also have her wedding bands made from these materials. The imagery and meaning behind a concrete wedding band is also powerful symbolically as concrete gets stronger over time and can be used to indicate the strength of the marital union. The designs themselves are only limited by the desires of the bride and groom and can range from fingerprint to filigree designs. A custom-made concrete wedding band can cost approximately $40 to $49 and can be appropriately brought to the altar on a concrete ring dish instead of the traditional pillow.
