For many 4×4 shops and Jeep 4WD owners, welding plays an important role. If you repair, modify or upgrade Jeep 4WD vehicles or four-wheel drive components, welding is a vital skill.

A professional weldor can do far more than run a bead. 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.
Jeep 4WD 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.
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 finished product.
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 hardness.
If you 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 techniques.
Follow my 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! Send me your questions through the welding ‘Q & A’…
