There are different types of welding, which leads to the need for different types of weld fasteners. There is not comparing one to the other as each is designed for a particular type of welding process and equipment. It is, however, important not to use the incorrect fastener type with the welding system.
However, the different welding results using resistance or arc welding systems can be compared for different types of work. The choice of using weld fasteners rather than having to drill a hole and use a bolt or other type of fastener is time-saving, cost-saving and requires the welder to only have access to one side of the workpiece.
The ability to create permanent fasteners that are welded to the workpiece and only require access to one side to create the system to attach the two steel plates or steel plates, girders or beams to another material is also important for aesthetic purposes. The positioning for the fastener on one side of the plate cannot be seen on the other side.
With arc welding, which may be called drawn arc welding, even small sizes of weld fasteners and thin workpieces can be attached using the process. A controlled electrical arc is used between the fastener and the workpieces, causing both to melt and form a pool of molten metal into which the fastener is pressed. This is done very quickly, so the rest of the workpiece does not become hot.
Resistance Welding and Fasteners
The use of resistance welding to apply fasteners is also common. There can be spot welding or projection welding. Both of these are often used for large plates and fasteners where additional heat, current, pressure and time are used to create the bond between the workpiece and the fastener.
