About products and suppliers

In seam welding, materials are joined together by a continuous "seam", stretching along the connection between them. This can be achieved in various ways, and you can fuse different materials if desired, making seam welders a good option for those who need flexibility and versatility. All of the major seam welder varieties can be found at Alibaba's wholesale store. So if you need a new circumferential welding machine and want maximum choice, you're in the right place.



When a new circumferential welding machine is required, Alibaba has the answer. Our seam welders catalogue covers ever imaginable variety, with some specialist welders that are hard to find elsewhere. One of the most common styles is a longitudinal welder. Also known as linear welders, these devices connect rectangular pieces along a single seam and are often used to create longer lengths of piping. Choose this style for working on gas or fluid management systems. Other products may be labeled as resistance seam welders, which produces gas-tight joints and is the gold standard for products like fuel tanks.



The seam welders selection at Alibaba.com isn't all about metals either. You'll find seam welders for plastics that can be used to create pipelines, larger sheets of PVC, or to connect plastic film for packaging tasks. These plastic welders tend to be more portable and can be wielded by hand. They also usually use hot air welding to create joins, and can work on virtually any type of plastic. Seam welding could work well in all sorts of situations, from making plane fuselages to crafting protective screens. And if you need a new circumferential welding machine, Alibaba will have the machinery required.
