The entire point of the weld test is to see if the weld or the material is stronger. A good weld would not break in the weld area as it is stronger than the base material. The specimen will always fail at its weakest point and production weld testing will find bad welds or processes.
@@jeongikkim3340 A proper weld should break outside the welded area with a properly machined specimen. If not there should be a specification assigned to it with a value for breaking strength.
Could you test a 16mm and 20mm deformed rebar welded joint just like you did there? Also advise the type of electrode you use. Do a plain bar as a benchmark to compare with. Add another coupler splice for comparison if possible. I need to see the test results please
Yes we can perform the testing for you. We do not do the welding in house as the customer would send a welded specimen to us for testing. Contact us for details! www.frankbacon.com or fbmechanicaltesting.com
Yes you could definitely test a 3mm thick specimen. That would not be an issue. We could either get you into a test system to bring your testing in house or we can test it for you. FB Mechanical Testing is our test lab division. Let us know how we can help!
@@davidcarao6421 Ok if you are following a specific standard such as AWS B4.0 then go exactly with what the standard says to do. Go with 38mm per the AWS procedure & specifications.
Do you have a video of doing CVN testing? Or would you be willing to make one? Thanks.
We do have a basic video of performing a Charpy Impact Tester on our channel!
if the break in the weld area does that mean the test is successful?

If the non heat treatable metals like ETP Cu or OFC is welded? Where would it break?

Hi Frank, I am a question, Could i make a tensile testing with 3mm thickness for stainless steel and aws 308l-16 electrode?

@@frankbaconmachinery hi Frank, thank you for you answer. for this specimen with 3mm thick i could to use the dimensions W as 38mm or as 25mm
@@davidcarao6421 For a 3mm thick specimen I would go with the smallest width so 25mm.
@@frankbaconmachinery ok, got it. but the norm AWS B4.0 figure 4.2, recommend me for T < 25mm ---> W = 38mm. i am confused.

How are test samples made?
First the two metals samples are welded per ANSI/AWS standards. Then they are cut into dogbone specimens on a mill, water jet or cnc machining center.
