TD339 Stagecraft III


Welding Projects

Spring 2008

Apart from the first project, it is expected that you spend a significant amount of time outside of class
in the completion of this work. Good welding takes lots and lots of practice. All of the preliminary projects
are designed to better your skills in preparation for the final project – which includes welds that must be
safe enough to hold human weight and other heavy objects without any possibility of failure.
Plan on being in the shop as much as three to four times per week working on these.

Don't forget that it takes time to set up all the equipment and that a one hour fire watch is
required at the end of every welding session. Also, if you're welding at times when the shop isn't
normally in operation, you'll need to recruit an assistant.

Due Date Project

(in class project)


EXPERIMENTATION
Complete the following from the Lab Manual, substituting
16-gauge, 2" square tubing in place of the plate steel:
1-9 (p.23) - Effects of Current Settings
1-10 (p.27) - Electrode Extension
1-11 (p.29) - Gun Angle
2-1 (p.39) - Stringer Beads
4-1 (p.163) - Stringer Beads on a 45° Angle

HORIZONTAL WELDING
Complete the following from the Lab Manual,
substituting 16-gauge, 1" square tubing:
(Repeat these projects several times and hand in your best work.)
Only make horizontal welds at this point.
Inspect your welds using the information
from pp.146-152 in the Classroom Manual.
2-2 (p.41) - Butt Joint

2-3 (p.43) - Lap Joint
2-4 (p.45) - Tee Joint
See also Griffin pp.93-99

VERTICAL WELDING
Using the unwelded, vertical joints from your
previous pieces, complete the following:
All welds should be done vertically at this point.
4-4 (p.169) - Butt, Lap, & Tee Joints (see also 4-12, p.187)
Corner Joint (similar to Griffin pp.97-98)

Ultimately, you should be handing in four total examples of joints.
Grind and clean up your best pieces before submitting them for a grade.
While it is possible to do all of these welds horizontally, if you don't practice
them now, it will come back to haunt you in your next two projects.

WELDING WORKBENCH

Build a welding workbench.
We will discuss materials and design in class.

 

5/2


FINAL PROJECT

Design and build an elevator trap that can raise an adult performer
a distance of at least six feet, using a predominance of steel.
(The platform, for instance, could be plywood attached to a steel frame.)
You will need to recruit assistants for your performer and any stagehands help required.
