Seam welding

Ideal for continuous welding of long welded materials! Resistance welding that allows for continuous welding.

We would like to introduce the 'seam welding' that can be handled by Tokiwa Bane Industry Co., Ltd. Using roller-type (cylindrical) electrodes, the workpieces are clamped from above and below, and while applying pressure and current, they are rotated to join. This method is suitable for continuously welding long workpieces. Since it can weld in a linear fashion, it is used for sealing welds in areas where airtightness is required. 【Features】 ■ Suitable for areas requiring airtightness ■ The joints are linear, so there are no breakages ■ Can weld even very thin plates ■ Work time is shorter than spot welding ■ The joining surface finishes beautifully *For more details, please refer to the PDF materials or feel free to contact us.

Seam welding | For products that require airtightness, such as tanks.

Welding used for products where airtightness is important, as well as airtightness inspection after welding, can also be accommodated.

Seam welding is widely used for products that require airtightness, and because it welds while sandwiching the materials, it can be performed even if the precision of the materials being welded is low and there are gaps between them. Our company has welded various sizes, materials, and thicknesses, from 4.5L portable cans to 200L home tanks. We can also weld materials other than iron, such as stainless steel, to meet customer requirements. Additionally, leveraging our experience in manufacturing gasoline portable cans, we can also conduct airtightness tests after welding. Because it provides higher strength compared to other welding methods, it has been used not only for tank products but also for a wide range of applications, including conveyor belt components. ◆ Technical Features - Capable of high airtightness welding. - A welding method with greater strength compared to other welding techniques. - Can weld even if the precision of the materials being welded is low, as it welds while sandwiching the materials. - We also possess vertical seam welding machines, allowing us to seam weld products without flanges. - Our company can also perform airtightness tests after welding. *For more details, please refer to the related links or feel free to contact us.
