Duties Before WeldingCheck all documentationCheck all consumablesCheck materials, dimensions and conditionPreheating, method and temperatureCheck fit and set-up.Ensure no undue stress is applied to the jointCheck welding equipment

M.S.Rogers

During WeldingCheck amperage, voltage, polarityEnsure the correct technique, run sequence.Check run out lengths, time lapses.Cleaning between passesInterpass temperaturesConsumable controlMaintenance of records and reports

M.S.Rogers

After WeldingPost cleaningVisual inspection of completed welded jointCheck weld contour and withPWHTDimensional accuracyWeld reportsTie up with NDTMonitor any repairs

TWI Multi-purpose Welding Inspectors GaugeM.S.RogersMisalignmentThe scale is used to measure misalignment of components by placing the edge of the gauge on the lower one and rotating the segment until the pointer contacts the higher pieceAngle of preparationThe scale reads from 0o to 60o in steps of 5o. The angle is read against the chamfered edge of the segment

M.S.RogersUndercutThe scale reads from 0 in the negative up to 5m. The segment is rotated until the pointer reaches the full depth of the undercut.Excess weld metalThe scale is used to read off these dimensions up to a maximum of 25mm and 1 inch60504001/41/23/4105101520INMMMM151/2TWI Multi-purpose Welding Inspectors Gauge

M.S.RogersFillet throat thicknessThe sliding pointer reads up to 20mm and 3/4 inch. In measuring throat thickness it is assumed that the fillet weld has normal root penetrationFillet weld leg lengthThe scale is used to read off these dimensions up to a maximum of 25mm and 1 inch.TWI Multi-purpose Welding Inspectors Gauge
