Resistance welding uses heat and pressure to create a bond between two materials. The heat generated by electricity in this type of welding. The materials typically joined together by resistance welding will be metal, but plastic can also be joined using resistance welding methods. If handled properly, resistance welding is a fast and efficient way to bond two pieces of material together. However, if not handled properly, the weld seam may crack or fracture, leading to many other problems.

Spot welding machine is a method of resistance welding used in small projects and maintenance processes. Spot welding is also used to bond metal sheets together. In spot welding, electricity is transferred between two copper electrodes, causing heat to melt and the metal sheets to bond together. Caused by heat, this also contributes to the adhesion of metal sheets. Another aspect of spot welding, as its name implies, is that the weld seam is strategically placed at small points, rather than long welds all along the edges where the two pieces of material are gathered together.

Flash butt welding machine is used to manufacture butt joints for straight or tubular components. For example, when two pieces of metal come together in a large size, this is the type that will be used for welding. For many people, this is what they consider to be the type of welded joint. This type of weld is used in the construction of large buildings, in certain areas of automobiles, and in other applications where large pieces of metal come together. This is a solid joint weld that, if handled properly, can be very strong. This type of welding requires high temperatures to complete.

Seam welding machine is used to seal the seam between two pieces of metal. It is necessary to use two wheeled electrodes for welding with this type. The wheel hub design of the electrode allows for long-term continuous welding of reinforced metal, making the weld seam as strong as possible. Many types of welding require one person to complete the correct welding, but welds are usually done by machines. This makes fast and precise welds very strong. After the product is produced by the machine, it will be manually inspected, and any errors will be fixed by manual spot welding.
