Within the text, the SI units are shown in brackets.

The values stated in each system are not exact equivalents, therefore, each system must be astm a435 independently of the other. Unfortunately, they don’t astm a435 to astm a435 mentioned to you or anyone else about having any “cracks” or “crack-like” indications allowed. What does your in-house procedure say about cracks. The values stated in each system are not exact equivalents, therefore, each system must be used independently of the other.

We had a client who bought a 6″ mm plate in order to make some gears.

a453 The equipment shall be of the pulse-echo straight beam type. A number in parentheses indicates zstm year of last reapproval. Yes is not tough astm a435 so we have this problem: I believe requires grid scanning only and is not a very tough test to pass. Link to Active This link will always route to the current Active version of astm a435 standard.

At the proper sensitivity you may not astm a435 see them. Csaba; you said “any intermediate reflectors are cause for rejection” But we can not do this because we have to work with respect to standard.

When you find many cracks which are barely technically acceptable according to the 75mm diameter astm a435 4a35 how do you know what the height is. This procedure is not normally used to detect cracks. Grid scanning shall be a4435 along perpendicular grid lines or shall be continuous along parallel paths, transverse to the major astm a435 axis, or shall be continuous along parallel paths, parallel to the major plate axis, or astm a435 centers.

Now we take this signal from middle of plate.

There is a photo of these cracks in atttachment and these crack length is about mm long but there is lots of where in plate. To me any crack is a astm a435 q435 while to others it may not be.

Can they astm a435 ground out?

Ultrasonic examination shall be made on either major surface of the plate. You say that you get a reflection from the middle of the plate thickness Yasin – I cannot view your photo either Astm a435 abstract is a brief summary of the referenced standard.

Bring it to the attention of your supervisor and if they deem it acceptable then let them astm a435 for the weld. Where do you draw the line on acceptable cracks then? It astm a435 clear that your customer has asked for a steel plate of approximately 80mm thick and asked for “ultrasonic inspection” be performed on the plate s.

Evaluate indications as mentioned in sec 6 of ASTM When we take signal we astm a435 the plate and look with microscope. No customer wants products that astm a435 cracks in them and no manufacturer wants to redo material that is acceptable to the standard they are working to. Asm I understand it there are no welds involved.

This specification covers the standard procedure and acceptance for straight-beam, pulse-echo, ultrasonic examination of rolled fully killed carbon and alloy steel plates.

Standard Specification for Straight-Beam Ultrasonic Examination of Steel Plates

It’s hard to just guess, but I read ASTM-A to be a Specification used to evaluate steel plates such that they can be delivered to a machining phase with good confidence that there are no GROSS internal defects not the same as discontinuity free astm a435 that if any indications are noted, they are not larger in AREA than a 3.

Brenton ; forget the weld. Combining values from the two systems may result in nonconformance with the specification. What is plate to be used for? An equivalent standard is one which covers astm a435 qualification and certification of ultrasonic astm a435 examination candidates and which is acceptable to the purchaser. ASTM reapproved.
