GTAW is the Gas-Tungsten Arc Welding process A defect means something's wrong with the weld. There are hundreds of kinds, and every kind of defect has a different cause--and sometimes there are seven or eight causes for one defect.
The defects detection is the validation process. The defects prevention is a verification process.
For GTAW Process use ER90-B9 and for the SMAW Process use E 9018-B9, or E 9015-B9
During the manufacturing process, once the product is finished, a quality control process is usually followed where defects are detected--hence defect detection.
GAS TUNGSTEN ARC WELDING
The Oxford Dictionary describes Defect in noun form as a shortcoming or fault, in verb form means desert one's country/cause/etc. for another. defect means like damage that happened during the manufacturing of the product.
The tip of the tungsten electrode has to be hot in GTAW because you are trying to weld two pieces of metal together, and that takes a lot of heat.
High frequency stabilized alternating current power supply is the most used GTAW process for aluminum with pure tungsten electrodes.
The purpose of shielding gas in Gas Tungsten Arc Welding (GTAW) is to protect the weld area from atmospheric contamination, which can lead to defects and weaken the weld. It helps to stabilize the arc and improve the quality of the weld bead. Common shielding gases used in GTAW include argon, which is the most widely used due to its inert properties, and helium, which can be used for specific applications to enhance heat input and penetration.
The term flaws is meant to state that there is a deficiency or imperfection within in a object or thing. Another accurate definition is that flaws indicate a defect impairing legal soundness or validity.
Incident is an unexpected behaviour which needs further investigation. It can be a defect in AUT, in Test case or in the test environment.
