Quality Control Tools

reduce the defects in Orbital TIG Welding
such as lack of fusion, porosity, mismatch, root
concavity, burn through, excess penetration,
incomplete penetration and other some major
defects are identified and the reasons for
occurrence are studied in detail, using the
statistical quality tools such as Pie-chart,
Histogram, Cause and effect diagram. After
introducing these tools the productivity in
TIG is measured. The major reasons for the
defects are analysed through constant
monitoring. Then improvised process and
results are achieved after changing the welding
parameters. Then the reduction in defects are
shown with the help of Pie-chart.
