Third-Party Welding Inspection Services

Your Global Welding Inspection Company

To ensure that the weld is of a high enough standard for its intended industrial application, quality assurance is crucial in welding. Mars Quality provides its services in inspection with extensive experience providing welding and related services both domestically and abroad.
The function of QC welding inspectors is crucial since they need to comprehend the welding-related drawings, symbols, joint designs, and procedures. For the purpose of removing flaws or discontinuities that go beyond what is considered acceptable, our welding inspectors execute welding inspection and testing in line with welding codes and standards. 

Responsibilities of Mars Quality:

• • • To verify and check the welder performance that the qualified welder will conduct or perform at your project.
    • To organize a cross-check of the materials that will be used in your project and to verify the factory test certificate.
    • Visual Examination.
    • Checking dimensions and tolerances against drawings, specifications, and contract amendments.
    • Magnetic particle testing or dye penetrant testing are used to discover surface and subsurface defects.
    • For discovering interior defects in welding, use ultrasonic or radiography testing.
    • Inspection of Coating Thickness and Roughness.

The Welding Procedure Specification will give welders or welding operators instructions on how to produce welds of sound and high quality that adhere to the requirements of the drawing and the code.

Before beginning the welding at your project, you need to engage a certified inspector to choose the best welder using several types of welding inspection test procedures.

QA/QC inspectors carry out fabrication inspection and manufacturing process verification. Inspectors verify Certified Material Test Reports (CMTR) for materials used and visually check materials to ensure compliance with approved specifications, plans, and codes.

Fabrication facilities monitor materials and components during critical stages of the manufacturing process. As appropriate to the project’s scope, Mars Quality, certified QC welding inspectors also observe welder and welding procedure qualification exams.

Our Third-Party Welding Inspection Services Routine

Different welding criteria, including as weld size, reinforcement, fillet size, weld coverage, and position, are checked to ensure the weld is proper and of high quality. To make sure the welded connection satisfies the performance and weld quality acceptance criteria, every aspect of the weld is visually evaluated. We do third-party witness and inspection of welding techniques and welder tests, which aid in reaching quality at its best price with industry safe standards.

As a third-party quality inspection service, Advising contractors on secure welding techniques. Operator requirements for welding automation. Outsourcing for project-based NDT management. Third-party witnesses for both non-destructive tests and laboratory metal tests, along with tests for tensile strength, bend strength, impact strength, macro- and micro-examination, hardness, chemical analysis, corrosion, etc.

Materials that we process our testing services on: Carbon Steel, Low Alloy Steel SS, Duplex and Super Duplex SS, Inconel, Aluminium / Welding Types: Welding & Weld Overlay (CRO, HFO).

Processes for welding include SMAW, SAW, GTAW, LBW, GMAW, and FCAW.

Some of our other enlisted procedures include:
Observing pressure testing of welded items such as pressure vessels, cross-country pipelines, gas pipelines, plumbing and fire-fighting pipes, process piping, and storage tanks using methods such as hydrostatic pressure testing, leak testing, pneumatic testing, and more. Applications include sheet metal, steel constructions, pressure vessels, storage tanks, and piping.
