Getting the right amps for TIG welding stainless steel is a balancing act. Too little current can leave a cold, sluggish puddle or incomplete fusion. Too much heat can cause burn-through, distortion, heavy heat tint, or loss of corrosion resistance.…
A poor MIG setup can ruin a weld before you pull the trigger. Gas flow, wire type, polarity, wire speed, voltage, clean metal, and the condition of your consumables all affect the final bead. Too little shielding gas can expose…
One thing I learned early in my welding career is that how you store low-hydrogen electrodes can make or break the result. I once grabbed a box of E7018 rods that had been sitting open in the shop. The arc…
Welding thin metal with self-shielded flux-core wire is possible, but the margin for error is small. Too much heat can open a hole or warp the sheet, while settings that are too cold can leave a raised bead with little…
Potassium chloride, usually written as KCl, is commonly used on the reference side of a pH electrode. It does not sense pH itself. Instead, it helps the reference system maintain a steady electrical potential so the meter can accurately interpret…
Undercut is the narrow groove that can form beside a weld toe or along a weld root when the arc melts base metal faster than the weld pool fills it. It may look small, but it reduces the effective section…
Pick the wrong welding process, and a simple repair can turn into extra grinding, poor fusion, excess distortion, or a weld that does not meet the job’s requirements. MIG vs TIG welding comes down to productivity, heat and filler control,…
One thing every welder learns sooner or later is that not every stick electrode can sit on the bench overnight and still perform the same the next day. Low-hydrogen electrodes can absorb moisture after their sealed package is opened, and…
Flux core aluminum welding rods sound like a gasless shortcut for welding aluminum, but that name is often misleading. Most products sold under it are low-temperature aluminum repair rods used with a torch. They do not work like steel flux-cored…
Flux core welding can feel rough at first. The arc is bright, the wire can spit, slag hides the bead, and thin steel can burn through quickly. The good news is that most beginner problems come from a small group…
