Turning a plate of steel into a finished part takes specialized equipment and a deep understanding of what the plate undergoes during the process. From heavy cylinders to frame rails to crane booms, large structures can be formed with a high degree of control, but different projects call for different pieces of equipment. AT&F has world class equipment and expertise in metal forming going back to the 1940’s so you know your project is in good hands, no matter the size or dimensions.
How Forming Works
AT&F Cooks for the House
After arriving at the Ronald McDonald House in Cleveland, OH, the team of AT&F volunteers quickly unpacked the groceries and began preparations. This was not their first time making dinner for the house, and their confidence in the kitchen was reassuring to many of the guests. The team prepared pizza and made good use of the four ovens in the kitchen. With up to 55 families to feed, dinner had to be big. Fortunately, a five-person team made quick work of the bulk-purchased food.
AT&F Welders Support Wounded Warrior Recognition
Continuing on AT&F’s tradition of close involvement with the U.S. Military and showcasing our respect for the men and women of our armed forces, AT&F has partnered with the Wounded Warriors Project to donate 40 trophies, laser cut and welded from stainless steel.
While one of the most widely used and accessible methods of welding, gas metal arc welding (GMAW) is actually a balancing act of many important variables that greatly affect the quality of the weld. Commonly known as MIG welding (short for “metal inert gas”), this method utilizes a consumable metal as an electrode like shielded metal arc welding in the form of a wire. The wire is fed semi-automatically or automatically through a gun that supplies the shielding gas necessary for protecting the weld pool from exposure to the atmosphere.
Chemical heat exchangers, dealing with volatile chemicals at high temperatures, are prone to corrosion. Fortunately, tantalum is one of the most corrosion resistant metals on earth. AT&F Advanced Metals has experience with many specialty metals, including tantalum, and have manufactured many tantalum heat exchangers, lined pressure vessels, and other specialty application components that make use of the metal’s properties.
TIG Welding: Precision and Preparation
When a welding job requires precision, the obvious method to use is TIG welding. Gas tungsten arc welding (GTAW) is a welding method using tungsten as an electrode and argon or helium gas as a shielding agent. When GTAW was first introduced in 1941, it used exclusively helium as the shielding gas. This gave it its original name: Heli arc welding. It is now referred to as tungsten inert gas welding, or TIG for short. It is a slow and difficult method to master, but a trained welder can use TIG welding to produce very high quality welds. But what makes TIG welding so precision oriented? And why do TIG welders have to feed the wire by hand?
From the Floor: Weld Institute Expansion
AT&F is an industry leader in welding capabilities, with in-house robotic welding, and a Weld Institute that teaches students the fundamentals of welding—as well as advanced techniques—courtesy of our highly skilled welding engineers. Our Weld Institute, formed in (2015), is currently undergoing repositioning and expansion to accommodate larger classes and cover more welding types.
Safety When Welding
Welding, like any job in a fabricating facility, comes with risks. Some risks are inherent to the craft, and some are factors of the environment, but all risks can be assessed and mitigated, if not completely eliminated, by following procedures. Safety has been a pillar for AT&F since our creation in 1940. The priorities that drive our business are “Safety, Quality, and Productivity,” in that order, and welding is no exception. Our in-house Weld Institute starts every course with an overview of safety to set the standard as soon as our welders begin learning. With 90% of all injuries in the workplace occurring due to operator error, preventing accidents like these begins with proper procedures.
Press Release: AT&F Wisconsin Upgrades Facility
AT&F is pleased to announce recent upgrades to our Wisconsin facility, including a brand new plasma and oxy-fuel cutting table with a 5-axis beveling head, and improvements to a large capacity boring bar. In addition to the equipment upgrades, AT&F Wisconsin is pleased to announce the addition of a Certified Weld Inspector (CWI) to further enhance the welding quality and provide a valuable resource for proper procedures and training. These upgrades are part of AT&F’s continuous improvement initiative and bolster the Wisconsin facility’s capabilities for a competitive market.
The History of Welding
For millennia, metals have been manipulated to man’s wants and needs. But from primitive hammers and anvils to high-tech robotic lasers, man’s methods of manipulation have changed and evolved drastically over time. The impact of advancements in welding has built skyscrapers, automobiles, and even nuclear reactors, but the genesis of welding looked nothing like the advanced technology we have at our disp
osal today. Paving the way for modern structures and safer machines, welding plays a crucial role in our daily lives.
