One of the most frequently used weld tests is the bend test because you can quickly perform it with simple tools. It tests the skill of the welder and the integrity of his welds. The theory of the bend test is that two pieces of metal welded together at the top should withstand a cert...
In the present study, extremely low cycle material fatigue tests were carried out to examine the fatigue failure mechanism of two types of welded structural details, which were the plate butt weld (PB) specimen and cruciform load-carrying groove weld (CLG) specimen. Fatigue tests were performed ...

The test objects include root-failed plug weld specimens, as well as toe-failed out-of-plane gusset weld joint and T-joint specimens. The welding residual stresses near the root notch and weld toe are measured by X-ray diffraction technique. The assessment of the mean stress effect on ...
The material adopts high-performance alloy steel according to USA API standard and strictly checked by chemical content, metallographic structure, geometric dimension, NDT tests etc to ensure the stable quality of the products. Process of drill pipe body ...
You can get a variety of eye injuries if you are not wearing proper protection, especially in high-risk jobs. High-risk jobs include anything that has chemicals, lots of dust, excessively bright lights, UV lights, compressed air or even machinery that can chip, cut, weld, sand and all th...
Socket weld flanges are generally used onsmall-sized pipesin high-pressure environments. To fix these flanges in place, the pipe is inserted into the socket until coming to the bushing or plug; the upper part is then lifted out slightly and welded. This means that the inside part of the...
Solder ball shear testing is one of the more common tests performed on the welding strength tester, Used to test the bonding strength between the tin ball and the substrate after the ball is planted Bump Shear Testing TRY PRECISION Multifunctional Push-pull Tester can conduct bump shear testin...
This chapter provides an overview of the common types of defects found in various structural materials and joints in aircraft. Materials manufacturing methods (including large-scale production) have been established in the aircraft industry. However, as will be seen in this chapter, manufacturing defec...
