METHODS OF STUD LOCATION
Economic stud location may be obtained using any one of the follow-
ing methods, depending on the type of work involved :
-
Tripod leg assembly.
Nose cone Ø20, Ø25, Ø30 mm Length 63
-
75mm.
Extended leg assembly.
TRIPOD LEG ASSEMBLY.
This is generally used for low volume production and one off compo-
nents. The spacing of the tripod legs allow for ease of stud placement
onto a scribed or pencilled mark. Centre punch indentations must not
be used.
NOSE CONE ASSEMBLY.
This is generally used for high volume and repetitive work, or where a
greater level of accuracy is required. Simple jigs made from Tufnol (a
thermo
-
setting plastic) or sheet metal can easily be made, allowing for
speedy and accurate production. Advice on jig manufacture can be ob-
tained from your sales representative.
EXTENDED LEG ASSEMBLY.
This is used where a requirement for welding very long studs is neces-
sary. The extended leg assembly allows studs up to 200 mm long to be
welded.
IMPORTANT NOTE !
Manual centre punch indentations must NOT be used for stud
location as this will have the same effect as shortening the pip
on the weld stud and could adversely affect the weld quality.
If practical considerations compel the use of indentations, then we
would suggest the use of either an automatic centre punch or a punch
press set only to produce the shallowest of indents consistent with the
ease of stud location.
The setting chart parameters may have to be altered to achieve the op-
timum conditions detailed in the setting up and welding procedure.
If in any doubt, please seek the advice of your local technical repre-
sentative.
