MECHANICAL TESTING

MECHANICAL TESTING  It determines the mechanical properties of the material. It is an important part of the product design and manufacturing process. Preserving the integrity of finished goods such as strength, toughness, hardness to ensure the safety and efficiency of material design.  There are 6 Main Services :

1. Tensile Test 

Our universal testing machine ranges in capacity from 50 kN to 1800 kN and is designed to perform tensile, compression, shear tests, and more. these systems are compatible with numbers of grips and fixtures in accordance with standards such as ASTM, ISO, JIS and other industry standards.

2. Bending Test

The bend test uses a coupon that is bent in three point bending to a specified angle. The bend test may be free formed or guided and is the type of test specified in the welding procedure and welder qualification specifications. For example, it may be a requirement in ASME , AWS , BS EN ISO  and more.

1.3 Hardness Test

A hardness test is a means of determining resistance to penetration and is occasionally employed to obtain a quick approximation of tensile strength.

-Rockwell hardness test (HRA, HRB, HRC)

-Brinell hardness test (HBW)

-Vickers hardness test (HV1, HV5, HV10)

1.4 Impact Test

A Charpy V-notch impact test is a dynamic test in which a notched specimen is struck and broken by a single blow in a specially designed testing machine. The measured test values may be the energy absorbed or the percentage shear fracture. Our impact testing machine meets the indirect verification requirements of the current ISO 148-2 and ASTM E23

1.5 Nick Break Test / Fracture Test

This test is useful for determining the internal quality of the weld metal to reveal the internal imperfections (if present) such as slag inclusion, lack of fusion, incomplete penetration, porosity, etc. The weld specimen is fractured along an artificial notch that is intentionally machined on the center line of the weld specimen to facilitate fracture in the center of the weld.

1.6 Flattening Test

The flattening test as commonly made on specimens cut from tubular products is conducted by subjecting rings from the tube or pipe to a prescribed degree of flattening between parallel. The severity of the flattening test is measured by the distance between the parallel plates and is varied according to the dimensions of the tube or pipe.
