The weld should bend, but not break. If it breaks, then the weld is brittle. Weld another test piece and clamp it in the bench vise. Hit it hard with a hammer. The weld should also bend and not break. If the weld fails either one of these tests, you need more practice. 2 ...
It is determined by analyzing a test ingot sample obtained during the pouring of the steel from a ladle. Lamellar TearA system of cracks or discontinuities aligned generally parallel to the worked surface of a plate. Usually associated with a fusion weld in thick plate. LaminationAn abnormal ...

You can also perform ultrasonic testing in accordance with EN10160 standard, EN10164 standard test Z15, Z25, Z35, weld bending detection, PWHT detection,etc. We have ISO9001: 2000 quality management system certification, and obtain the quality certification from all the well-known certification...
A Charpy impact test is applied on LTCS at − 46°C to evaluate the resistance of the materials against breakage. A V-notch is created on a sample of the material (see Fig. 12.21) and the required energy to break the material through the V-notch is measured. The mechanism of low ...
Some customers require a randomly selected destructive test on the welds as well. Cutting, bending, or flattening the weld occurs in order to ensure it comes apart in the correct manner. If a weld does not become destroyed in its intended way, that means it was not welded accurately. ...
Test 1. Our stretch correcting machines can check chains link by link, can guarantee weld quality. If welded place break when stretch, then the chain will not pass the test, as waste product. 2. After finish produce, will choose several links randomly, do the breaking ...
355JR steel is a high tensile strength structural steel which can be readily welded to other weldable steel. J denotes the notch impact test (done at; JR: room temp, J0: 0 °C; J2: −20 °C). The simple meaning is that S355JR can withstand an impact energy of 27 J at ...
Microstructural elements reported to affect localized corrosion behavior are metal sulfide inclusions (Ca, Mg, Mn sulfides), the pearlite structure (preferential iron dissolution on pearlite phase), microalloying metals (e.g., Cu), and weld zones (e.g., preferential attack of the heat affected zo...
