Template Method

• This method of templating is recommended for use with full base ferrules.

• The template is usually a bakelite plate 2 mm to 5 mm thick. 

• Spacers are required to allow the gases to escape during the welding cycle.

• The ferrule can be held by a standard ferrule grip or where clearance is prohibitive a tube type set-up can be used.

• The recommended hole sizes on the template to locate the ferrules should equal the maximum outside diameter of the ferrule plus 1 mm.

• Holes may be drilled or bored at required locations. See stud specification sheets for ferrule details.
