MIG Welding Explained: How GMAW Works, Where It Fits and Where It Doesn’t
Plain-English guide to MIG (GMAW) welding: wire feed, shielding gases, transfer modes, ER70S-6 wire, flux-core outdoors, common defects and when a mobile welder picks MIG over stick.
A Practical Guide to Welding Processes: Stick, MIG, Flux-Core and TIG
A practical comparison of SMAW, GMAW, FCAW and GTAW welding: how each works, strengths and limits, best metals, outdoor use, cutting and brazing, joint types, prep and finishing.
Truck Frame Welding: What Is Safe, What Is Regulated, and What to Ask First
What is safe and legal in truck frame welding: manufacturer body builder guides, heat-treated rails, FMCSA 49 CFR 393.201, bolted reinforcement, inspection and when a welder declines.
Automotive Welding Basics: What Can Be Welded on a Car or Truck, and What Shouldn’t
What is safe to weld on a car or truck: exhaust, brackets, body panels and rust repair, versus unibody structure, suspension, steering and fuel tanks that need a body shop or replacement.
Steel Support Beams for Load-Bearing Walls: How the Welding Fits Into the Job
How a steel beam replaces a load-bearing wall: engineer sizing, permits, shoring, footings, bearing plates, and where field welding fits into the job.
How Aluminum Is Welded: Processes, Prep and Why It Is Harder Than Steel
Why aluminum is harder to weld than steel: the oxide layer, AC TIG and spool-gun MIG, cleaning, 4043 vs 5356 filler, preheat, HAZ softening, porosity and cracking.
Automotive Frame Welding: Unibody vs Full Frame, and the Repair Rules That Apply
Unibody vs body-on-frame, why high-strength steels cannot be MIG-welded conventionally, manufacturer procedures, frame measuring, airbag and insurance issues.
Common Automobile Welding Repairs and How They Are Done Properly
Exhaust, brackets, floor patches, hitch mounts, aluminum tanks and cast manifolds: how each automotive welding repair is done, the prep, and the safety limits.
