What is a Simulator ? • Simulator is a software that provides the user an Interactive Virtual Experience of Reality. • A good Simulator captures the Physical Phenomena using Mathematical Models through Software & Graphics. • Every Simulator balances accuracy with resources and speed.

Weld Inspection In Simsonic, weld geometry can be defined internally using Pre-defined Objects option. The type of Weld can be selected from the list as shown in the following snap-shot:
Weld Inspection (Contd.) The Weld Geometry is defined using parameters as shown in the diagram
Weld Inspection (Contd.) The video in the next slide shows the A-scan with different wedges at different positions for the above sample. It may be noticed that for the wedges L45, L60 and S30, echo from different regions (front wall, side walls and from the beads) are received and it would be difficult to identify the echo from the defect in the weld. With the wedge S45, the echo from the defect can be seen distinctly and though the ray picture shows some rays received from the sidewall, they are very weak in intensity. Likewise, a right wedge can be selected in SimSonic to detect defects.
Weld Inspection (Contd.) For the weld sample with S45 wedge, the echo from the defect are well detected. The A-scan with and without defect are shown below: The A-scan drawn in red color dotted lines is without defect and the A-scan drawn in green color is with the defect.
