2. Strike arc precisely
in center of broken stud and begin build-up. Take your time. Continue re-striking
“dead-
center” on build-up. (See Figure
2). Building-up deposit off-center will cause stud to be welded to sides of
cavity.
Do not overheat. Allow build-up to cool. 3.
Before building
deposit above top of cavity, allow weld deposit to cool. This precaution will
help avoid welding
deposit to top
edges of cavity. 4.
Carefully chip away only top center of slag. Build-up
enough deposit above top edge of cavity to be able to
weld a nut and
washer to deposit without welding them to part edges. 5.
Allow deposit
to cool slightly. Weld a washer and nut of same or smaller size to built-up column
of metal to
center of deposit.
(See Figure 3). Do not weld nut and washer to part edges.
6. Allow
assembly to cool before using a wrench, or appropriate tool, to unscrew broken
part. If there are any (Fig.
