These materials possess similar properties such as excellent formability, weldability, and strong corrosion resistance. Cylinders can be furnished with custom features including ribbed, custom formed ends, fittings, side holes, and weld flanged options. Forms are created by rolling flat sheets into a round shape, then sealing with a seam weld produced with Jetline TIG welding equipment. Once the metal cylinder is welded, the planishing operation also realigns the molecular structure of the metal to its original state. Our processing yields accurate dimensions, with smooth, strong weld seams.
Size capabilities for cone and cylinder parts are up to 72 in. in length, diameters from 5.5 to 48 in, and thicknesses from 0.030 to .134 in. The tightest tolerances of ±0.030 in are met for parts up to 1 ft in length, with higher tolerances for larger parts. Turnaround times are 2 to 4 weeks, and all parts and processes meet ISO standards as well as our own internal standards for excellence. Value added additional services include secondary forming, welding, metal finishing, engineering support, stamping, embossing, extruding, and, of course, spinning.
There are cut out, edge, profile and welding options available to customize the cylinder for a specific metal fabrication application. Toledo Metal Spinning Company forms and welds high quality sheet metal cylinders to work with other TMS products. Double flanged cylinders are used as non-welded spacers to extend the height of the deep drawn cups and hoppers. When welded construction is preferred, either a plain or single flange cylinder can be TIG welded to either the conical or flat cylinder ends. Using the cylinders in conjunction with our stock metal spun hoppers, deep drawn cups and stainless steel lids will permit a rapid development of a vessel that can be used for several applications mentioned below. For more information about our custom cone and cylinder fabrications or our other available services and products please see the table below or contact us directly.

Rolling
We can roll up to 6’ in length with up to a 4’ diameter. The thickess can range from .032” thick to .250” thick with materials like cold rolled steel, hot rolled steel, various stainless steels, and aluminum. Copper, brass, and Inconel are also available to roll.
Tabbing
Once the parts are rolled in the Davi roller, we take them over to the tabbing station to tab each end of the cylinder. The tabs are welded to the ends of the cylinder to prevent “blow through” on the cylinder ends. The seam welder will initiate the weld on the tab outside of the main cylinder and continue seam welding throughout the length of the cylinder and onto the exit tab.
Longitudinal Seam Welding
In our large roll and seam weld cell, we have a state of the art Davi roller. The large longitudinal seam weld cell can roll a minimum of .032” thick up to .250” thick by 6′ in length and 5′ in diameter.
Planishing
Once the seam welding is complete, the cylinder is taken over to the planishing machine to flatten the weld to near flush with the cylinder. Then, the cylinder goes to the cutoff machine to remove the tabs. Voilà! The cylinder has nice and even ends.
Flanging
At this point, the cylinder could be finished or it could go to the flanging process. We are able to make a single flanged cylinder or a double flanged cylinder. The customer can choose what flange radius they would like. The standard choices available are 1/4”, 3/8”,1/2”, 5/8”, or 3/4”, the radius depends on the material type and thickness. Typically, a radius of at least three times metal thickness is acceptable.
Material Types
The machine capacity will have a bearing on what the final dimensions of the rolled and welded cylinder will have. This is determined based on the material type, thickness, length, and diameter of the part to be formed. The different material types that can be used on the small and large longitudinal weld cells include but not limited to the following:
Lean Manufacturing ; One Piece Flow Technology
Instead of batching parts between each machine, one part is fabricated at a time so that when the part comes out of the cell, it is complete and ready to ship or go to the next cell or department. This method of manufacturing reduces the overall time that it takes to make a completed part.
Frequently Asked Questions about Rolled and Welded Cylinders
Our Rolling process begins with a laser-cut blank that we cut in-house. The blank is then put into our rolling machine, where it is rolled to a specified diameter.
Cylinders can be furnished with custom features including ribbed, custom formed ends, fittings, side holes, and weld flanged options. Forms are created by rolling flat sheets into a round shape, then sealing with a seam weld produced with Jetline TIG welding equipment. Once the metal cylinder is welded, the planishing operation also realigns the molecular structure of the metal to its original state. Our processing yields accurate dimensions, with smooth, strong weld seams.
Seam welding is the process of joining two similar or different materials together, at the seam, through the use of electronic currents and pressure.
How it works:
The gap creates an electrical resistance between the materials, which causes them to heat up at the seam. This process is most common with metals, because they conduct electricity easily, and are able to sustain high pressures. Seam Welding has a great reputation for building a clear weld every time, without needing filler.
A technical definition would be: as the current passes between the metals, heat is generated at the gap. The electrodes maintain and control the flow of electricity
As a welder, understanding the way the process works is extremely important. The amount of heat generated at the seams depends on the magnitude of the current flowing through it - too much electricity can cause deterioration. Another key factor is taking into account the type and hardness of the materials. Harder materials will need more welding force, than softer materials.
Seam welding is an automated welding process that produces airtight Welds quickly and efficiently. There is no filler required, helping lower costs and production time. Seam welding has a great reputation for providing a clear weld, and is one of the only welding processes that does not emit fumes or cause any gas formation, as with other processes.
It is also possible to combine seam welding and spot welding to create gas-tight and liquid-tight joints.
Seam welding is utilized for the cylinder forming process, ensuring a strong weld every time. A tab is welded onto the cylinder for a complete weld from start to finish, for weld integrity. After the tabs are cut off, a continual, dependable weld is left, all the way through the cylinder's edges. Our automated welding systems and skilled welders provide a consistent and even weld, which is highly rated in our industry. Because of our technology, a consistent and repeatable weld is provided for every part, every single time.
After achieving the seam weld, we planish the weld to ensure that it is smooth all the way down the cylinder. The planishing process means that the molecules are realigned in the weld, which makes the weld much stronger and more reliable. It is possible to combine seam welding and spot welding to create gas-tight and liquid-tight joints, which is necessary for certain cylindrical components. All of our custom cylinders are made with a dependable seam weld to be utilized for any application.
Once the seam welding is complete, the cylinder is taken over to the planishing machine to flatten the weld to near flush with the cylinder.
Planishing is a highly effective technique used to reduce weld build-up and enhance the cylinder or tank's surface finish of the welded areas. The planisher seamlessly blends the weld into the surrounding base metal, increasing its strength and durability. This also allows for a finish to be added rather easily, if needed, while eliminating the need for grinding.
After the planishing process is complete, the cylinder goes to the cutoff machine to remove the tabs. Voilà! The cylinder has nice and even ends, with a seamless and durable weld that extends through the entirety of the part.
The machine capacity will have a bearing on what the final dimensions of the rolled and welded cylinder will have. This is determined based on the material type, thickness, length, and diameter of the part to be formed. The different material types that can be used on the small and large longitudinal weld cells include cold rolled steel, hot rolled steel, various stainless steels, and aluminum. We can also roll Copper, brass, and Inconel.
There are four common types of electric resistance welding:
- Resistance Spot Welding
- Projection Welding
- Butt Welding
- Seam Welding
