Welding Inspection Standards Quiz

Cracks that occur in the heat affected zone (HAZ) near the weld due to the melting of low melting point constituents in the material.

Cracks that form during the cooling and solidifying process of the weld metal, often along the center of the weld.

Cracks that are caused by the presence of hydrogen in the weld metal, occuring after the weld has cooled.

Cracks that occur in the weld metal due to a high carbon or impurity content in the weld.

Cracks that occur in the HAZ and are influenced by the geometry of the weld and the type of metal used.

A type of cracking caused by the weld metal's resistance to tearing in the direction parallel to the weld bead, often related to the layering of materials.

Cracks that develop from a central point and radiate outward like spokes on a wheel.

Cracks that branch out from a main crack, forming a interconnected network.

Reference samples help define acceptable standards for weld details like surface finish, toe blend, and root profile.

A welding inspector ensures that all inspection tools are in good condition and properly calibrated based on quality control standards.

Welding inspectors must prioritize safety by understanding regulations and ensuring the availability of appropriate safety equipment.

Before welding, materials must match drawings or WPS, have traceable test certificates, and be free from damage or contamination.

Welding Procedure Specifications (WPS) must be approved and readily available to both welders and inspectors.

All welding equipment needs to be in good working condition and calibrated according to the appropriate standards.

Welding preparations must adhere to WPS or drawing specifications to ensure proper join alignment and joint fit-up.

Welders must be qualified for each WPS used, and their certificates must be current.

The minimum light intensity required for visual weld inspection, as per ISO 17637. It recommends 500 lux, but the minimum is 350 lux.

The distance from the eye to the weld surface during visual inspection, ensuring adequate detail visibility.

The minimum angle required for a clear view of the weld during visual inspection. It ensures the inspector can see the full weld profile without obstruction.

Specialized tools used for visual inspection of restricted areas, often used in agreement with the client and fabricator.

A visual inspection performed on a weld after welding is completed. It's a minimum requirement for all welds, but can be followed by other inspection methods.

The document or agreement that defines the extent and stages of required weld inspection activities, specifying the necessary inspection procedures and methods.

Specialized tools used for measuring weld dimensions and characteristics, ensuring conformance to design specifications.

The tools used for measuring the distance between the welding surfaces before welding. It's crucial for ensuring proper weld penetration and joint preparation.

Small, hollow spaces or holes within the weld metal caused by trapped gas during solidification.

Caused by moisture or contaminants on the welding surface, electrode, or filler material.

Elongated or tubular cavities formed by trapped gas in the weld metal, often appearing in groups.

Caused by trapped gas as the weld solidifies, often due to contaminants or inadequate surface preparation.

A gas pore that breaks through the surface of the weld, forming an open hole.

Occurs when gas is trapped in the weld metal during solidification, resulting in a variety of pore shapes and sizes.

Ensure surfaces are clean and free from contaminants before welding.

Use dry electrodes and minimize air entrapment.

A small, round hole or cavity in the weld metal caused by gas entrapment.

A type of porosity where gas cavities are evenly dispersed throughout the weld metal.

Porosity that is clustered in specific areas of the weld.

A large, elongated cavity in the weld metal, often found under the weld surface.

Porosity that appears as a line or series of small holes along the weld bead.

A shrinkage cavity at the end of a weld run, usually caused by cooling and contraction of the weld metal.

Solid foreign substances trapped in the weld metal, such as slag or metal oxides.

A process of reducing the weld current in a series of steps to avoid excessive shrinkage at the end of a weld.

A type of destructive test that measures a specific mechanical property of the weld, like tensile strength or hardness.

A type of destructive test that assesses the overall quality of the weld, looking for defects or soundness.

A destructive test used to verify that a welded joint is free from defects and meets quality standards by applying a bending force.

A destructive test that involves examining the fracture surface of a broken weld to identify the cause of failure.

A type of destructive test designed to assess the strength of a welded joint by pulling the test piece apart.

A specific type of transverse tensile test used to evaluate the strength of a welded joint.

A set of standards specifying the dimensions and procedures for conducting transverse tensile tests.

A requirement for transverse tensile tests in welding procedure qualification. It ensures that the welded joint meets the strength requirements of the design.

A union of pieces of metal made by welding.

An operation where two or more parts are joined by heat, pressure, or both.

The metal added during welding to fill the gap between the pieces being joined.

The metal melted during the welding process and retained in the weld zone.

The part of the parent metal that is affected by the heat of welding but not melted.

The boundary between the weld metal and the HAZ in a fusion weld.

The zone that includes both the weld metal and the HAZ.

The surface of a fusion weld exposed on the side where the weld was made.

The zone on the side of the first run furthest from the welder.

The boundary between the weld face and the parent metal or between runs.

Weld metal lying outside the plane joining the toes.

The angle at which the edge of a component is prepared for welding.

The angle between the planes of the fusion faces of parts to be welded.

The portion of a fusion face at the root that is not bevelled or grooved.

The minimum distance at any cross-section between edges or surfaces to be joined.

The radius of the curved portion of the fusion face in a component prepared for a single or double J or U weld.

The straight portion of a fusion face between the root face and the radius part of a J or U preparation, usually 0.

A weld where the weld metal fully penetrates the joint with complete root fusion.

A weld joint without full penetration.

An imperfection produced by a local rupture in the solid state, which may arise from the effect of cooling or stresses.
