Improve Your Welding &
Brazing Skills—Right Here!
motorcycle work can involve swapping engines, installing lift kits, building roll cages and tire carriers,
restoring vintage Willys frames or repairing the broken and fatigued chassis of a Jeep CJ or Wrangler. To do
this properly requires a knowledge of metals, especially their tensile strength, metallurgy and chemistry.
Filler rod or wire must match the base metals; aluminum requires special TIG (GTAW) welding; and each carbon
steel has its preferred welding method.
This section of the magazine offers
in-depth welding and brazing tutorial and how-to articles. Topics include learning to weld and braze,
metallurgy and safe use of welding equipment. Learn to weld properly and fabricate metal

Moses Ludel has welded
professionally and instructed welding processes and metals fabricating. Improve your skills at gas welding and
brazing, 'stick' SMAW welding, MIG/GMAW wire feed and spool welding plus the art of TIG/GTAW welding.
Professionalize your welding skills and make better Jeep modifications and repairs. There is much more to
welding than 'running a bead' on metal! Learn about steel alloys, heat treating, case hardening, metallurgy,
casting repairs and choosing the best materials for your project.

Apply various welding
techniques to your Jeep projects. Learn stick, MIG and TIG welding, gas welding/brazing and plasma
cutting techniques. Repair a Jeep 4WD frame, build a roll cage, create off-road accessories, build a
trailer, fix axles, weld alloy steel, tubing, aluminum and stainless steel, Modify or repair Jeep 4WD
suspension, axles and gear cases, using metallurgically correct, structurally sound
Fabricating with metal always
involves cutting. Plasma cutting, oxygen-acetylene, bandsaw or hole saw cutting is all part of metal
fabrication. Learn the various options for preparing and fitting metal pieces for welding and how to
avoid damaging sensitive heat treating and case hardening.
MIG or 'GMAW' is today the most
popular welding process for fabrication and industrial use. Many 4x4 shops and Jeep 4WD enthusiasts
have a wire-feed MIG machine. While MIG is fast, "forgiving" and quick to learn, there are many ways to
improve your MIG welding skills. Learn when and how to use MIG process.
TIG (GTAW) weldors earn respect
throughout the welding industry.This welding method, once associated with aluminum 'Heli-Arc', is now
used for titanium, all alloy steels, aluminum and stainless steel welding. Mastering TIG is both
creative and productive. TIG welding offers controlled, penetrating heat, precise filler deposits and
exceptional fusion. Requiring focus, good hand-to-eye coordination and the utmost cleanliness, TIG
welding can produce high strength, precise welds.
Welding properly and getting
safe, strong results require an understanding of metals and processes. This includes heat treating,
annealing, normalizing and case hardening. You need to know how heat affects metals. Choosing the right
filler materials or welding and brazing process depends on metallurgy, not guesswork or
A weldor is only as good as the
welding equipment—and vice versa!...Moses Ludel introduces Jeep 4WD enthusiasts and 4x4 shop owners to
quality, cost-effective welding and cutting equipment. Perform safe Jeep maintenance, restoration,
upgrades and modifications. Learn which tools and welding equipment will prove most useful and
cost-effective over time!
Moses Ludel has welded
professionally and taught adult vocational education welding and metal fabrication courses. He
understands metallurgy firsthand. Find answers or submit your own questions on welding and brazing
processes. Get professional answers, including the right choice of metals and filler materials for your
Jeep project. The punishment of desert racing and backcountry trail pounding demand the right
materials, most effective welding techniques and filler material choices for safe, lasting
If you repair, modify
or upgrade Jeep 4WD vehicles or four-wheel drive components, welding is a vital skill. This section of 4WD Mechanix
Magazine focuses on welding, brazing and safe metal handling practices. Safe, reliable fabrication work requires the right metal, the right
filler material and the right welding methods.
I have welded for over four
decades and instructed vocational adult welding for six years. Today, I approach the fusion welding processes,
brazing and spray welding techniques with a deep respect for metallurgy and a clear understanding of the best
practices for joining and repairing metals.
Welding requires hand-to-eye
coordination and the mastery of welding principles. Brazing and silver brazing are much different than fusion
welding; often, one process will work better than the other. The base metal has certain chemical and tensile
properties, and welding must respect these properties. If not, the end result will be a weaker, failure-prone
For that reason, the welding and
fabrication section at the 4WD Mechanix Magazine website
includes welding methods and an ongoing discussion about metals and structural design. Learn how I make crack-free
cast iron weld repairs, build strong motor mounts, construct roll bars and create frame brackets. Metallurgy is a
regular topic, including heat treating processes, case hardening, annealing and restoring tensile strength and
can benefit from stick (SMAW), MIG (GMAW) or TIG (GTAW) welding, brazing, silver brazing or plasma cutting, this
section provides the how-to articles, step-by-step welding videos and slide presentations to improve your welding
and brazing skills. Aluminum welding, silver brazing, working with case hardened metals and welding mild and
low-alloy carbon steel—each requires the right process, the right
technique and the right filler materials.
I enjoy welding and sharing the
various processes! Once past the basics, you will discover the creativity and problem-solving benefits of welding
and brazing. In addition to my HD videos and articles covering gas, stick, TIG and MIG welding, we'll explore newer
niche processes like metal spray welding and advanced TIG
how-to restoration tips for saving obsolete metal parts, including gears, brackets, iron castings and even 'pot
metal' or die castings. I encourage your mastery of welding, metals fabrication and metallurgy! Watch the
