POSSIBLE WELDING DEFECTS
POSSIBLE WELDING DEFECTS POSSIBLE WELDING DEFECTS
POSSIBLE WELDING DEFECTS
DEFECT CAUSES ADVICE
POROSITY Acid electrode on steel with a high
sulphur content.
Excessive swinging of the electrode.
Distance between the parts to be
welded is too great.
Part being welded is cold.
Use a basic electrode.
Move the edges to be welded closer
together.
Advance slowly at the start.
Decrease the welding current.
CRACKS Material to be welded is dirty (e.g. oil,
paint, rust, oxide).
Insufficient current.
Cleaning the parts before welding is
a fundamental principle for obtaining
good welding seams.
POOR
PENETRATION Low current.
High welding speed.
Inverted polarity.
Electrode tilted in position opposite
its movement.
Regulate the operative parameters
and improve preparation of the parts
to be welded.
HIGH SPLASHING Excessive electrode inclination. Make the necessary corrections.
PROFILE DEFECTS Incorrect welding parameters.
Passing speed not linked with the
needs of the operative parameters.
Electrode inclination not constant
during welding.
Respect the basic and general weld-
ing principles.
ARC INSTABILITY Insufficient current. Check the state of the electrode and
the connection of the earth cable.
THE ELECTRODE
MELTS
OBLIQUELY Electrode with core not centred.
Magnetic blowing phenomenon.
Change the electrode.
Connect two earth cables to the op-
posite sides of the part to be welded.
