Bend Tests for Welded Materials

WELD BEND TESTS Bend tests are applied to welded metal strips in order to test the material at the bend location. Bending of the specimen is done around a cylinder of specified radius through a given angle. Once bent, the tested strips look like the letter U. The maximum extension occurs at the outside of…

Tensile Tests for Welded Materials

TENSILE TESTS Tensile/tension testing is a destructive test whereby controlled tension is applied to a sample either as a load for proof testing or until it fully fails. This is used to find out how strong a material is and how much it can be stretched before it breaks. This test method is used to…

Macro Examination for Welded Materials

MACRO EXAMINATION Macro examination is a procedure in which a specimen is etched and evaluated macro-structurally at low magnifications, typically x10 or lower.   For checking the quality of welds, macro examination can also be performed on a polished and etched cross-section of a welded material. During the macro examination, several features can be determined, including…

Micro Examination for Welded Materials

MICRO EXAMINATION   Micro examination is performed on samples either cut to size or mounted in a resin mold. The samples are polished to a fine finish, normally one-micron diamond paste, and usually etched in an appropriate chemical solution prior to examination on a metallurgical microscope. Magnifications of x50 and above are used for micro…

Notched Impact Tests

The Charpy/Izod impact tests are standardized high strain-rate tests, determining amount of energy absorbed by a material during fracture. This absorbed energy is a measure of a material’s notch toughness and acts as a tool to study temperature-dependent ductile-brittle transition. It is widely applied in industry due to easy to prepare and quickly and cheaply…

Welding Charpy Izod Test

Ultra-Low Refrigerated-Heating Circulators Welding Charpy Izod Test. Ultra-Low Refrigerated Circulators for heating and cooling. The units are suitable for external temperature applications with simultaneous operation in the bath tank. The units provide particularly high heating and cooling capacities for rapid heat-up and cool-down times even for large volume, external systems. ‚FP‘ models offer proportional cooling…

Carbon & Sulfur Analysis

  In accordance with ASTM E 1019 standard of combustion method, C & S analysis are conducted in our laboratory.   We started to analysis C & S in such various kind of materials as cast iron, ductile iron, cast iron with lamella/spherical graphite, ferro-alloy scraps and slags.
