Stress - Strain - Elongation - Fracture

The skill of welding operator is fore most factor to achieve high quality welds and hence one has to verify and ensure the welder performance before initiating any project.

Welder performance can be assessed by making few weld coupons depends on type of intended job and tested as per applicable codes as well standard specifications to access the welder skill. Upon qualifying the tests welder can be considered for making sound welds.

It’s good to have demonstrate the welder performance against his skills and capabilities to follow the welding specification to ensure weld quality as well trust among the customers.

Our Mechanical Testing facility has been instrumental in qualifying Welding Procedure Specification and Welders for our various clients through PQR Test and WQT Test.

VARIOUS APPLICABLE STANDARDS AND CLASS

We undertake Procedure Qualification and Welder Qualification for various applicable standards and marine class which include:

• ASME BPVC Section IX
• AWS D1.1
• Marine Class DNV GL
• Marine Class LR
• Marine Class ABS
• Marine Class ClassNK
• Marine Class IRS
• Marine Class GL

SIGNIFICANCE OF TENSILE TEST

Typically, the NDT and destructive mechanical tests required for such qualification include:

• Radiography
• Magnetic Particle Test
• Liquid Penetrant Test
• Tensile Test
• Bend Test
• Charpy Impact Test
• Macro Etch Test
• Weld Hardness Survey
• Microstructural Test

EILAB CAPABILITY FOR PROCEDURE QUALIFICATION TEST

Typically, the welder qualification tests may include the Non-Destructive testing (Radiography) as well Visual examination, destructive/mechanical testing in accordance with the relevant standard specifications. EILAB is equipped with inhouse testing facilities for NDT, Mechanical property evaluation as well Metallurgical examination in less turn around lead time.
