Wavebit Infratech Interview Questions and Answers

There are various types of welding positions, including flat, horizontal, vertical, and overhead positions.

• Flat position: Welding is performed on a horizontal surface.

• Horizontal position: Welding is performed on a vertical surface with the weld axis in a horizontal plane.

• Vertical position: Welding is performed on a vertical surface with the weld axis in a vertical plane.

• Overhead position: Welding is performed on a surf

DPT stands for Dye Penetrant Testing. It is used to detect surface defects in non-porous materials.

• Ensure the surface is clean and dry before applying the dye penetrant.

• Apply the dye penetrant evenly and allow it to dwell for the specified time.

• Remove excess penetrant and apply developer to draw out any defects.

• Inspect the surface under appropriate lighting conditions for indications of defects.

• Evaluate the indications

DPT Accepting Criteria refers to the set of conditions that a product or system must meet in order to be accepted for use or release.

• DPT Accepting Criteria are the requirements that a product or system must fulfill to be considered acceptable.

• These criteria are typically defined by the quality control (QC) team or the customer.

• They may include factors such as functionality, performance, reliability, safety, and complia...read more

Electro rod backing is a process used in welding to provide support and stability to the electrode rod during the welding process.

• Electro rod backing is used to prevent the electrode rod from bending or sagging during welding.

• It involves attaching a backing material to the electrode rod to provide support.

• The backing material can be made of copper, aluminum, or other heat-resistant materials.

• The backing material is typ...read more

Methods used to create WPS

• Welding Procedure Specification (WPS) can be created using various methods.

• One common method is to follow the guidelines provided by welding codes and standards such as AWS D1.1 or ASME Section IX.

• Another method is to conduct welding procedure qualification tests to determine the parameters for the WPS.

• WPS can also be created by referencing existing qualified procedures and making necessary mo...read more
