“Man, that looks sweet! It would be cool if you did a video on the
weld. Is that too much to ask?”

Not really set up to do video but I plan to show in great detail how I
welded and tested by destruction my hemi-joint threaded tubing inserts
(bungs). This will be reflective of my unique and particular
hemi-joint threaded tubing insert (bung) welding experience and only
relevant to the variables related to my particular set of materials,
welding, and weld testing.  If the welding of my hemi-joint threaded
tubing inserts is successful, it is in no way a guarantee, that
someone else with a different set of materials, machines, welding
abilities, methods, and technique variables would achieve the same
results.
I currently have four extra hemi-joint threaded tubing inserts on
order to be used for welding and weld testing by destruction. I have
added  this from the Miller Welding forum

MILLER WELDING FORUM: Hemi-joint threaded insert welding.
Note: Suspension and steering related hemi-joints are considered to be
critical welded parts in that weld/part failures could result in
severe injury and death. If you don’t have absolute confidence in your
parts/materials, welding, and weld testing, knowledge and abilities,
take them to a professional welder.
Here is the related posting.
“Now some will say they got nice hot welds on the bungs they did with
MIG. I do not know what their experience is but having a MIG weld go
in "nice and hot" is certainly no guarantee if it is sound or not.
Only practicing and destruction testing on your welds will show if
welding and parameters were correct. So, I buy some extra bungs and
weld them as practice. Once welded, I cut long and sideways through
the center and examine for fusion. This is the only way I can know for
certain. Anytime I change any variable such as tubing material, even
the thickness, hemi-joint threaded insert material/dimensions, welding
wire/rod, welder settings, etc. I destruction test the new welded
combination. It is the only way I can be certain that my welding and
parameters were correct.”

I posted a copy of this post here because it might be of some benefit
to anyone planning, starting, or currently building a Batman Tumbler.

Here from weldguru.com is the best and most comprehensive article I
have ever seen on the web for assessing and testing the quality of
welds. I put the table of contents below. Go to weldguru.com to read
the whole 2593 words on the subject. It is very informative and worth
reading for anyone interested in, and/or worried about the quality of
their welds.  vertigo

Guide to Weld Quality Testing
“To ensure the satisfactory performance of a welded structure, the
quality of the welds must be determined by adequate testing procedures.
Therefore, they are proof tested under conditions that are the same or
more severe than those encountered by the welded structures in the
field.”

This page contains visual inspection tips. The following pages contain
inspection methods for GMAW and physical weld testing.

Here is one the most comprehensive websites I have found for MIG welding.

Weldguru.com

“Hi, my name is Garrett… (owner of weldguru.com)

For the past 5 years I’ve helped well over 10,000 beginners and
hobbyists get started learning to mig weld through my free training.

With the recent postings focus on welding I have decide to post on a
question frequently asked of me by those interested in or new to
welding.

“What is the best start out welding book for someone wanting to learn
about or improve on their minimal welding abilities?”

The best current book that meets the needs of those wanting to learn
about or improve their minimal welding abilities is: The Art of
Welding

It really has no current competition in succinct to the point
descriptive text or quality of photo images and illustrations.

Many Junior High schools, High schools, colleges, and welding schools
now use this as their 101 welding introduction text.

The Art of Welding
by  William Galvery
former Professor of Welding Technology
Orange Coast College of California
With input from Ryan Friedlinghaus
Founder and CEO of West Coast Customs
