Did you know that brazing is often used in welding? With brazing, two pieces of the same type of metal are joined by a filler metal that is heated hotter than the melting level. As that filler cools, the process joins the two similar metals together. It is a type of soldering.
In manufacturing, cast iron is typically heated until it liquefies, and then it's poured into any of a variety of molds. As it cools, it becomes brittle and can even shatter if treated roughly. What makes cast iron so brittle? It's made using a relatively high percentage of carbon.
Once your construction company starts taking on more large contracts, it’s a smart idea to begin working with welding contractors. This will ensure that the welding is completed by a professional welder while still allowing other aspects to be completed by your crew.
During World War II, many of London's iron railings were removed. Though the government claimed that the iron was used for ships and munitions, many suspect it was unusable and dumped into the Thames or given to British colonies.
If you have steel or other metal that needs holes or slots, we can help. Depending on what is the best application, we will drill, plasma cut, laser cut, or flame cut the metal to your specifications. Call or bring in a sample.
Though usually thought of as an older decorative form, wrought iron is making its way back into home décor. Wrought can be manipulated into a number of different styles and shapes for banisters, fireplace screens, as well as gates.
In oxy-fuel welding, a torch is used to join metals. As in other types of welding, the pieces of material are heated to the melting point, and a filler material is added to create a strong joint. The type of filler material varies according to the materials being welded.
Iron work can be as large as a balcony rail or as small as hand crafted handles for your kitchen cabinets, and anywhere in between. Why not speak to a master iron worker and see what they have to offer?
There are many advantages to shielded metal arc welding (SMAW). The process is relatively simple, which helps to keep down costs, and it’s versatile and thus good for confined spaces and out of position welding.
Most custom installed ironwork railings, gates, and doors have preinstalled frames or similar fixtures in place that allow for easy assembly, reassembly, or replacement should you need to replace or redisign the pieces.
The 5-story iron frame at the Oswego Starch Factory in New York is possibly the largest iron structure in the world. It weighs around 300,000 pounds, and is made from huge hollow iron columns.
What’s the difference between “fusion” and “penetrate” when it comes to welding? “Fusion” refers to how deep the weld pool goes into the surface of the base metal, whereas “penetrate” distinguishes how far the weld pool goes into the joint.
Interior and exterior metalwork can add distinct elements to your décor. The metal naturally provides contrast in terms of color and texture while imparting interest and beauty to make a unique design statement for your home.
Did you know that welding techniques were developed as early as the Bronze Age more than 3,000 years ago? It was during this time that experiments with newly discovered metals – and their alloys – laid the groundwork for today’s welding technologies.
Many items described as wrought iron made today are actually made from mild steel. They are still referred to as wrought iron as they were worked by hand historically.
The earliest form of welding was actually called "forge welding" and was performed by blacksmiths. The blacksmiths would heat the metal until it was bright red, and then pound the two pieces of metal together to form a bond, using an anvil.
It’s the finials that give an iron fence or railing its authentic traditional look. Finials are one of the easiest parts of the fence to customize and come in a wide range of design styles, from pointed to rounded to crimped.
Because oxygen and nitrogen can create brittle and porous welds, as early as 1890, C.L. Coffin was promoting gas shielding to create a non-oxidizing welding environment. The technology didn’t fully evolve until the 1920s, when H.M. Hobart began using helium to create a gas shield.
One of the benefits of railing made with wrought iron is that it’s extremely strong and can stand up to practically anything. Due to its construction, its form is also streamlined, which means it takes up less space than other materials.
Did you know that early blacksmiths were regarded as sorcerers and magicians for the way that they could shape iron and other metals? Their craft was held in high regard as they used the elements fire and water to shape matter.
Shop welding and fabrication can be used in conjunction with field fabrication. It can also be used in the fabrication of saws, shears, benders, drill presses, and plasma cutting equipment, along with catwalks and steel and stainless steel structures.
Did you know that there are many different forms or methods used for welding? Welding can be done using various tools including electric arch, gas flame, laser radiation, electronic beam, rubbing, and ultra-sound.
Ironwork is malleable, which means it's flexible and can be manipulated into lots of different shapes. Iron gates and other artistic or functional objects made from iron can conform to almost any architectural style and work with any motif you have in mind.
So what’s the difference between the welding process and other methods of joining two pieces of metal together, such as soldering and brazing? In soldering and brazing, the metal pieces being joined remain unaltered, whereas welding always changes the workpieces.
The cast iron fence around St. Paul's was disavowed by Christopher Wren, the cathedral's architect. The original fence was molded in the Weald of Kent and weighed two hundred tons. It cost over 11,000 pounds, all paid for by a tax on coal.
While iron furniture, railings and staircases will last for generations, rust can be a concern with time – especially in areas where the iron has been chipped. If you see rust forming on any areas on your ironworks, be sure to remove the rust immediately.
An alloy of iron is often used to reinforce concrete structures. Can you guess this alloy? If you guessed steel, you're right. Reinforcing steel rods used in construction are often referred to as "rebar."
