Have any of you ever used this test and is it an effective test to determine weld strength. Any links to info on weld test is appreciated.
There is no single test for determining weld strength. It depends on what aspect of "strength" is of interest. Destructive testing takes place on a "coupon" which is subjected to different individual tests. The ASME codes (3 and 8) used to give details of various tests, as I recall for pressure vessels. For other applications of welding, look at the applicable code, e.g. for construction.
Otherwise, try one of the weld societies or manufacturers of welding rods. And Lincoln does have a fine reputation.
Finally, if your product is being tested for an export market, it is worth checking the national or international standards that will apply as well as the compatibility of materials standards (American vs other nationals, e.g. British, German whatever.)
If you do not have the in-house facilities, look for a certified laboratory or independent weld testing service. They will be sure to have the necessary standards, equipment and so forth.
Hope that helps.
