Our laboratory perform examinations in order to
investigate the cause of damages in connection
to failure. A part of the work is examining the
obtained materials through ocular, macroscopic and
microscopic examinations (through optic microscopes
and in a Scanning Electron Microscope), a so called
metallographic examination.

A basic definition of a damage or a breakdown is
the ability of a component, machine or process to
work in a correct and expected way. A breakdown and
damage analysis can involve extensive examinations,
which besides metallography also includes chemical
analyses and mechanical testing. The purpose of all this
is to find the cause of the incurred damage or failure
and through this be able to recommend applicable
measures to be taken and changes to be made.

Often a single cause isn't the basis for a damage or
failure, usually several factors comes into play. In some
causes, the absence of one of the contributing factors
have been enough to prevent a damage/breakdown.
The important part during an investigation is to keep
an open mind and not only focus on the most likely or most
easily accessible cause (a silver bullet theory, if you will),
since the cause can have many facets.

Damages and breakdowns can have causes such as
fatigue, corrosion, defects, temperature effects, choice of
materials, environmental factors and overloading to
mention a few. Safe Control has years of experience and
competence regarding problems and damages connected
to welding technology.
