Learn how to record a sudden increase in MIG spatter, check consumable identity and separate equipment, distance and arc-control questions.
Lack of fusion: why a tidy bead does not prove a bond
Learn what lack of fusion means, why access and travel matter, and how to organise a controlled investigation before changing settings.
TIG end craters: plan the finish before stopping the arc
Understand why a TIG weld can end in a hollow, how current and filler coordination matter, and when a suspect termination needs assessment.
Between-pass slag removal: what to check before welding again
Learn where slag can remain between weld passes, how to organise a cleaning checkpoint and why a clean surface cannot prove internal soundness.
