Seam welding is the process of joining two similar or different materials together, at the seam, by electronic current and pressure. 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 can sustain high pressures. Seam Welding has a great reputation for building a clear weld every time, with no filler needed. 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.
It is crucial to understand how the process works, because 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 the most common welding process, used to join metal sheets with a continuous, seamless weld.
It is possible to combine seam welding and spot welding to create gas-tight and liquid-tight joints.
At Toledo Metal Spinning, we utilize seam welding for our cylinder forming process. This ensures a strong weld every time. For weld integrity, we weld a tab onto the cylinder for a complete weld from start to finish. After the tabs are cut off, a continual, dependable weld is left, even at the 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.
What is the Trimming Process and How is it Performed? Trimming is a process used to remove excess material to achieve a desired shape, size, and finish, while removing burrs and smooths out sharp edges. To trim a part, it is put on a lathe and processed by a highly skilled metal spinner, or a
The Metal Finishing and Polishing Process The polishing process is a secondary metal fabrication process that is done to create a smooth and shiny surface by utilizing abrasives or chemical treatment, and can be done by hand or robotic automation. The purpose of adding a finish or polish is to improve the appearance by creating
Metal Fabrication: What is the Beading and Edge Rolling Process? Beading and edge rolling are the metal forming processes of adding a radius, raised edge, or indented ridge along the edge of a piece. This process is done to increase stability and durability of the part, and can also increase its functionality by allowing for
Secondary Metal Fabrication Processes At TMS, our secondary metal forming processes consist of: Beading and Edge Rolling Trimming Welding Metal Finishing and Polishing Each process can be done manually or automated, depending on the part. Beading and Edge Rolling Beading is very similar to edge rolling. During the beading process, a radius is added to
The Benefits of One-piece Constructions At Toledo Metal Spnning Company, we have been forming metals since 1929. With nearly a century of experience, we have mastered a wide range of processes including laser cutting, metal spinning, deep drawing, machining, rolling and seam welding, to build strong and durable high-performance parts. But what truly sets us
Laser Cutting 101 What is laser cutting and how does it work? The laser beam is a heat source which can melt metals rather quickly. When the concentrated beam comes into contact with the material, in this case, metal, the beam’s energy is absorbed into the metal, causing it to melt. However, the laser beam
Laser cutting produces efficient, precise cuts with smooth, uniform edges in both small and large runs on materials up to 1 in. thick. It’s no surprise that the process has become extremely popular, and manufacturers and fabricators now rely on laser cutting more than ever. Laser Cutting Basics A laser is a source of intense
Cylinders – The Forming Process Custom cylinders are made through a process that begins by putting a flat sheet of material into the laser and programming it to cut rectangles out of various materials to specific sizes. If the cylinder has any customizations or features including custom holes, windows or other shapes, these are cut
What is Weld Distortion? Weld Distortion is the deformation or misalignment of metal components caused by the expansion and contraction of the weld metal and base metal during welding process. This occurs accidentally, and there are many techniques to avoid distorting the metal throughout the welding process. Weld Distortion occurs when an incorrect amount of
