Why does CIGWELD 170 HF have gas pockets or porosity in the weld metal?
Porosity in the weld metal of your CIGWELD Welding System can occur due to several reasons: damp electrodes, which can be solved by drying electrodes before use; welding current that is too high, which requires a reduction in welding current; or surface impurities like oil, grease, or paint, which means the joint needs to be cleaned before welding.
What to do if the CIGWELD 170 HF Welding System weld run does not fuse to the metal surface?
If portions of the weld run in your CIGWELD Welding System aren't fusing to the metal surface, consider these factors: small electrodes used on heavy cold plate – use larger electrodes and preheat the plate; welding current being too low – increase the welding current; wrong electrode angle – adjust the angle to direct the arc into the base metal; travel speed of the electrode being too high – reduce the travel speed; or scale/dirt on the joint surface – clean the surface before welding.
How to fix a gap left by failure of weld metal in CIGWELD Welding System?
If your CIGWELD Welding System leaves a gap due to the weld metal not filling the root, it could be because: the welding current is too low, so increase it; the electrode is too large for the joint, so use a smaller diameter electrode; there's insufficient gap, so allow a wider gap; or the sequence is incorrect, so use the correct build-up sequence.
Why is there cracking in CIGWELD 170 HF weld metal after solidification?
Cracking in the weld metal of your CIGWELD Welding System shortly after it solidifies can be attributed to: joint rigidity, which can be fixed by redesigning to relieve stress or using crack-resistant electrodes; insufficient throat thickness, so travel slightly slower to allow greater build-up; or a cooling rate that's too high, so preheat the plate and allow it to cool slowly.
