Welding to Win with Joe Gibbs Racing® Courtesy of Lincoln Electric Hidden along a tree-lined parkway of unmarked office buildings in suburban Charlotte, North Carolina, lies a brand new steel-and-glass white structure that could be home to any number of corporations in any industry. But through the main door it becomes clear that this is something more than an insurance agency or software firm. It's home to Joe Gibbs Racing®, bejeweled in trophies, racing jackets and display cases literally filled with artifacts from the nation's fastest growing sport. Past the receptionist, across the main lobby, an observation deck overlooks one of the most advanced auto shops in the world. Through a panel of high windows is a conspicuous absence of grease stained floors and stray tools. Instead, the vast open space of more than 150,000 square feet shines in pristine white and better resembles an operating room than a fabrication shop. It's a virtual racecar laboratory, where engineers work side-by-side with master fabricators to create the fastest machines possible within the guidelines established by their sport. Those team fabricators, in turn, rely on the welding experts at Lincoln Electric®...

Courtesy of Lincoln Electric TIG WELD 4130! The Lincoln Electric Company, Welding Services. June 2000 Yes, you can TIG weld 4130 tubing up to .120" wall thickness easily with the techniques and procedures described in this bulletin. Answered are the top ten most frequently asked questions about TIG welding 4130 Chrome-Moly. These attached procedures apply to typical sporting applications such as experimental airplanes, racing car frames, roll cages, go-carts, bicycles, and motorcycle frames. The suitability of these techniques and procedures must be evaluated for your specific application. Q. Can I weld 4130 using the TIG process? A. Yes, 4130 Chrome-Moly has been TIG welded in the aerospace and aircraft industries for years. As with all welding, proper procedures and techniques must be followed. Q. Do I need to pre-heat? A. Thin wall tubing (< 0.120" wall) applications do not typically require the normal 300ºF to 400ºF pre-heat to obtain acceptable results. However, tubing should be at room temperature (70ºF) or above before welding. Q. What filler material do I use? A. Although there are several good filler materials, ER80S-D2, is one you should consider. This filler material is capable...

Plasma Cutting: Determining if it's Right for You and What to Look for in a Machine Introduction Do you need a cutting tool for occasional repair and maintenance work? Have you recently embarked on a new project that requires higher cutting volumes? Or, are you looking for a new alternative to your current mechanical saw? All of these scenarios provide great reasons to investigate plasma cutting. With the cost of machines on the decline, smaller-sized, portable machines flooding the market and technology offering increased benefits and easier usage -- it may be time to take a serious look at plasma for your cutting applications. The benefits of plasma cutting include ease of use, higher quality cuts and faster travel speeds. What is Plasma Cutting Technology? In simplest terms, plasma cutting is a process that uses a high velocity jet of ionized gas that is delivered from a constricting orifice. The high velocity ionized gas, that is, the plasma, conducts electricity from the torch of the plasma cutter to the work piece. The plasma heats the workpiece, melting the material. The high velocity stream of ionized gas mechanically blows the...

How To Successfully Weld Aluminum with a Compact MIG Welder from Lincoln Electric By Jim Harris®, Product Manager, The Lincoln Electric Company and Frank Armao, Group Leader, Non Ferrous Applications, The Lincoln Electric Company When it comes to welding aluminum items around the home or garage, there are a few misconceptions we hope to clear up: 1) That you need to invest in a $4,000 welding machine and be highly skilled to have success; 2) With no practice you can make excellent welds the first time the wire feed welder is taken out of the box; and 3) You need an expensive spool gun suited for aluminum. The truth is that with practice, the right equipment and proper set-up, a compact MIG welder will be able to tackle occasional aluminum welding jobs. Using your MIG welder, you will be able to work on a variety of items around your home and yard, such as grills, railings, backyard furniture, boat docks and even decorative elements. Compact MIG welders, such as the SP, Weld-Pak or Pro models from Lincoln Electric, are available at distributors and retail outlets. A Word About Aluminum...
