@@vivekravindran4472 could you please Elaborate your Question or share the Background of your Question.

There are two methods, I explained in the video. Either method can apply..For example, as you mentioned for 30-degree dihedral Angle, you can use the graph shown in the video at 21:38 to find the dihedral angle. Regarding the second part of your question, if you’re dealing with an angle for which we don’t have a graph, such as the 25-degree dihedral angle you mentioned, please note that the method no. 1, which I explained in video..can be applied. This approach works for angles that don't have corresponding graphs. Finally, remember that the local dihedral angle depends on three elements: brace angle, stub diameter and chord diameter.

Different types of joints and welding processes require different bevel angles for preparing the joints. Here are some common bevel angles: - V preparation: groove angle 50~60 degrees (both sides) / Single side 25~30 - Single bevel preparation: 40-50 degrees. These angles can vary based on factors like structure design welding methods and cost considerations. For Exact requirements. it is best to check the Welding Procedure Specification (WPS) for the specific project.

Thanks for comments, sure i will try to upload more Videos.

The work piece should have enough thickness. Please check the user manual of leeb hardness tester you are using. Generally Without coupling leeb hardness tester is not recommended for 4mm thickness. In addition, leeb hardness test on rod or tube may not be accurate when curvature radius of surface is less than 30mm for D, DC, D+15, E , DL impact device and less than 50mm for G type Impact device.

Sure Dear i will prepare and upload one Video on DAC

It's quite straight forward. On 3 points: Get the reflection at half-skip .. mark. Get the reflection at full-skip .. mark. Get the reflection at 1 1/2 skip mark. Proceed to deeper holes and repeat. On 2 points ID-OD notch: Same procedure basically. Before all that make sure your index point is marked on the probe and that you have set the sensitivity at 80% FSH.

Ahora incluí subtítulos en español en Video. Por favor mira mi video y dame tu opinión. Gracias

It's all depends on acceptance criteria... Just take the example of ISO ISO 23279 and ISO 11666, in accordance with afore stated standards all planner indications are not acceptable. and Lack of side wall fusion falls under Planner Category.

@@TechMechX so all planer defect rejected.

@@allwinthivan6795 yes if you are doing UT as per ISO standards and your acceptance criteria is ISO 11666. Remember same rule doesn’t apply if you are doing UT in accordance with AWS D1.1. Even In AWS D1.1 there are different, different criteria, base on structural loading such as static / cyclic etc. So As I mentioned earlier it’s depends on Acceptance criteria and governing code against which Examination is being performed.
