At Welder Testing Inc., we provide industry-leading mechanical testing services to evaluate the properties and performance of welded materials. Our well-equipped facility and experienced team ensure that all testing is conducted with precision, adhering to the highest industry standards. Mechanical testing is a crucial step in verifying the strength, durability, and reliability of welded components across industries such as oil and gas, petrochemical, power generation, shipbuilding, and heavy manufacturing.
Our mechanical testing services include a range of critical tests that assess material properties under various conditions. These tests are conducted to ensure compliance with AWS, ASME, ASTM, and other relevant industry codes and standards.
Tensile testing measures the strength of a welded material by applying controlled force until failure. This test helps determine:
Ultimate tensile strength (UTS) – The maximum stress a material can withstand before breaking.
Yield strength – The point at which the material begins to deform permanently.
Elongation and ductility – The material’s ability to stretch before breaking.
Reduction of area – The amount a material contracts at the point of fracture.
Tensile testing is essential for verifying the mechanical integrity of welding procedures and ensuring they meet required specifications.
Hardness testing assesses the resistance of a material to deformation, penetration, or wear. We perform hardness testing using various methods, including:
Brinell Hardness Test (BHN) – Suitable for softer metals and materials with coarse structures.
Rockwell Hardness Test (HRB, HRC) – Measures hardness based on the depth of penetration of an indenter under load.
Vickers Hardness Test (VHN) – Uses a diamond-shaped indenter for precise hardness measurements on thin materials or small areas.
Knoop Hardness Test (KHN) – Ideal for microhardness testing, particularly for small welds and coatings.
This test is valuable for assessing the material’s resistance to wear and potential brittleness, ensuring long-term durability.
Impact testing determines a material’s ability to absorb energy under high-strain conditions. This is particularly important in applications where welded structures are exposed to extreme temperatures or sudden force. We perform:
Charpy V-Notch (CVN) Testing – Measures a material’s toughness by striking a notched sample with a pendulum hammer and analyzing the absorbed energy.
Drop Weight Testing – Determines a material’s ability to resist brittle fracture under sudden impact.
These tests are crucial for industries such as offshore drilling, shipbuilding, and heavy equipment manufacturing, where materials must withstand harsh environments.
Metallographic examination involves microscopic evaluation of a weld’s internal structure. This test helps assess:
Grain size and microstructure
Heat-affected zones (HAZ)
Presence of inclusions, cracks, or other defects
We follow ASTM E 562 for Determination of Volume Fraction by Manual Point Count, ensuring precise and reliable results for weld evaluation.
Bend testing evaluates the ductility and soundness of a weld joint by bending a sample at a specified angle. This test helps identify surface and subsurface discontinuities, such as lack of fusion or excessive porosity, ensuring weld quality and adherence to procedural standards.
Mechanical testing evaluates the strength, durability, and reliability of welded materials to ensure they meet industry standards. It helps verify compliance with AWS, ASME, ASTM, and other relevant codes, ensuring welds can withstand operational stresses.
Industries such as oil and gas, petrochemical, power generation, shipbuilding, and heavy manufacturing rely on mechanical testing to confirm the integrity and performance of their welded components.
Tensile testing measures a material’s response to tension, determining:
Hardness testing assesses a material’s resistance to deformation and wear. We use methods such as Brinell, Rockwell, Vickers, and Knoop hardness testing to determine a material’s durability and suitability for various applications.
Impact testing, including Charpy V-Notch (CVN) and Drop Weight Testing, determines a material’s ability to absorb energy under sudden force. This is crucial for structures exposed to extreme temperatures or high-strain conditions.
Guided bend testing evaluates the ductility and soundness of a weld by bending a sample to a specified angle. It helps detect surface and subsurface discontinuities, such as lack of fusion or porosity, ensuring high-quality welds.
Metallographic analysis uses microscopic evaluation to examine grain size, heat-affected zones, inclusions, and weld defects. This helps ensure material consistency and proper welding procedures.
We adhere to industry standards such as AWS, ASME, ASTM, and ANSI to ensure reliable and compliant test results. Our lab is also ISO/IEC 17025 accredited, ensuring technical competency.
Turnaround times vary depending on the complexity of the test, but we prioritize fast and accurate results. Contact us for expedited services if needed.
