Stick Welding Porosity Checklist
Porosity in stick welding shows up as gas pockets in the weld metal. The usual causes are moisture, contamination, poor technique, or unstable shielding from the electrode. Use this checklist to isolate…

MIG Porosity Causes and Fixes
MIG porosity is gas trapped in the weld metal as it solidifies. It usually shows up as pinholes, worm tracks, or a rough weld surface. The main causes are shielding gas problems,…

TIG Welds Turning Black and Sooty? Fix Gas Coverage Fast
If your TIG welds are coming out black, sooty, or “dirty,” you’re not alone—this is one of the most common early warning signs of shielding gas problems. It usually shows up mid-bead…

Bad Gas Coverage in MIG Welds? Replace Your Nozzle
Intro Your MIG welds are porous, and you can see the problem: the shielding gas isn’t covering the weld pool. The arc is exposed, hydrogen from the air contaminates the molten metal,…

Why Your TIG Welds Have Porosity (And How to Fix It in 15 Minutes)
Porosity in TIG welds—those small gas pockets trapped in the bead—kills strength and fails inspections. The good news: most porosity is caused by three fixable issues: contaminated gas, weak shielding coverage, or…

TIG Gas Lens Cups Cracking? Replace Them Before Porosity Hits
Intro Your TIG welds are starting to show porosity or inconsistent gas coverage. You’ve checked your argon flow, regulator pressure, and torch angle. Everything checks out—except the welds still look rough. The…

Worn MIG Contact Tips Causing Porosity? Here’s the Fix
Intro Your MIG welds are coming out porous, weak, or with inconsistent penetration. You’ve checked your gas flow, wire speed, and voltage—everything looks right. The culprit? A worn contact tip. A degraded…
