WELDING ATTACHMENTS
Weld heads or welding hand attachments will be chosen based on electrode access, and the type
of application. When both sides (top and bottom) of the work piece can be accessed, an OPPOSED
type weld head or welding hand attachment is ideal. When the user only has access to one side
of the work piece, either a PARALLEL weld head or a welding hand attachment can be used. Weld
heads are typically the best option, as the welding force is consistent from weld to weld, and is not
dependent on the user.
ELECTRODE CONFIGURATIONS
is figure shows several electrode configurations used
in resistance welding. Example A is called a direct weld.
Current is passed from one electrode through both
workpieces and out an opposing electrode. Example B
shows a step electrode configuration. is configuration
is used when there is access to only one side of the workpiece and an electrode can be placed on
both materials. Example C is a series configuration. Electrodes can only be placed on one metal
surface from one side. Current is divided between the two parts. is weld configuration requires
more weld energy.
