Seam welding is a variation of resistance spot welding. In resistance seam welding , however, the welding electrodes are motor driven wheels as opposed to stationary rods.

The seam may be a butt joint or an overlap joint and is usually an automated process. It differs from butt welding in that butt welding typically welds the entire joint at once and seam welding. FAQ: Preparing cast iron for .
FAQ: What is friction seam welding ? Intended for impenetrable sheet metal seams. Many engineers and welders find themselves confused with the difference between stitch welding and seam welding since they are often used interchangeably, but there is a definite difference between the two types of welds. In the welding fabrication worl it is important to distinguish the two because . In mash seam welding (RSEW-MS), there is a small overlap of sheets, typically about one to two times the sheet thickness. Sheets are then mashed together while current applie making a solid state joint. This final joint thickness can be . The seam welding process is an adaptation of resistance spot welding and involves making a series of overlapping spot welds by means of rotating copper alloy wheel electrodes to form a continuous leak tight joint.
The electrodes are not opened between spots.
Spot welding is most often used to connect metal parts that are usually around mm thick. The material to be welded is put between two copper electrodes. Electric current flows through the material to weld the two metals while pressure on them is maintained.
Intermittent and continuous seam welds are very similar. In fact they can be run on the same machine. The only difference is the spacing of the weld. A change in the machine settings could produce either weld. A continuous seam weld is one where the individual spot welds produced overlap and normally form a fluid tight.
Find out information about seam weld. A longitudinal weld joining of sheet-metal parts or in making tubing. Arc or resistance welding in which a series of overlapping spot welds is produced.
Explanation of seam weld. A form of resistance welding that uses copper roller electrodes to provide a continuous run of overlapping spot welds. Resistance seam welding.
One of the electrodes may be driven by an electric motor. The workpiece is moved between the rollers and pulses of current are supplied. Roller seam welding ensures continuous, tight weld seams in sheet metal processing and achieves higher cycle times than spot welding.
From Smallest Welding Spots to Continuous Seams.
