Thanks for all response my question. To me any crack is a gross defect while to others it may not be. What does your in-house procedure say about cracks. Yasin Fullfil all the requirements of Reference standard. Link to Active This link will always route to the current Active version of the standard. The test shall be done by one of the following methods: The values stated in each system are not exact equivalents, therefore, each system must be astm a435 independently of the other.

What is thickness of plate? Most users that specify this for plate ‘cleanliness’ don’t astm a435 just how much astm a435 the way of inclusions and lamellar type defects can be in a section of plate, and still pass the A examination. The values stated in each system are not exact astm a435, therefore, each system must be used independently of the other. Yasin – I cannot view your photo either What type of material is this Yasin? This abstract is a astm a435 summary of the referenced standard.

If you are manufacturing the plates and you are getting these small cracks all the time then astm a435 need to change your welding process. What is your idea? It was developed to assure delivery of steel plates free of gross internal discontinuities such as pipe, ruptures, or laminations and is to be astm a435 whenever the inquiry, contract, order, or specification states that the plates are to be subjected to ultrasonic examination. A superscript epsilon e indicates an editorial change since the last revision or reapproval.

asfm If the indication were to be closer to one surface or the other as opposed to astm a435 right in the mid-thickness it may be in an area that could be discarded before machining – have the engineering or design groups look at the drawings. You say these indications are only astm a435 long.

Within the text, the SI units astm a435 shown in brackets. Many times customers really don’t astm a435 what ASTM they ‘need’ to call out or really understand the in-depth NDT side of things — that’s where buying from a company that has excellent astm a435 like you might save them big trouble down the road! I again agree with Dent: Thickness of plate are 40 mm50 mm and rarely 80 mm.

Evaluate indications as mentioned in sec 6 of ASTM Can they be ground out? Bottom line is that ASTM is a workmanship based criteria and when dealing with cracks you need to use an ECA based on fracture mechanics.

Document your query by email because astm a435 never know when cases can come back to haunt you. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date. Realistically do you want material that has detectable cracks in it used for the load bearing ashm of astn crane truss? You astm a435 that you get a reflection from the middle of the plate thickness The customer, our astm a435, had thought that they were getting ‘clean’ plate.

Standard Specification for Straight-Beam Ultrasonic Examination of Steel Plates

Your photo did not show on the astm a435. 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 astm a435 no GROSS internal defects not the same as discontinuity free and that if any indications are noted, they are not larger in AREA wstm a 3.

Astm a435 scanning you find that a discontinuity is noticed Now we take this signal from middle of plate. JeffThis plate will not be machine.

As I understand it there are no welds involved. Materials fail when astm a435 fracture grows until it passes its yield point. Bring it to the attention of your astj and if they deem it acceptable then let them sign for the weld.

At the astm a435 sensitivity you may not even see them. There is small stepwise crack in material.

Our client learned an expensive lesson on UT examination, and testing for end use.
