Mechanical testing for Welding Quality Control
(1130 votes)Welding Quality Control
Mechanical Welding-testing is regarded as the most reliable and least expensive to determine strength and other properties. Welding-testingspecimens to destruction is one of the most important means to assess the quality of welds. The other complementary element, you can find in another page, is nondestructive WELDING INSPECTION of actual welded structures.
Among mechanical Welding-testing, classic tensile tests are performed using instruments called Universal Mechanical Testing systems, on prepared test specimens precisely machined through weld material to the dimensions and shape required by Standards. Sometimes Specifications require to get strength results in the weld equal at least to those of the base metal. Other times they permit that a weld exhibit a given percentage (80%, 90%) of the base metal strength.
Do you need a fancy Lab. for testing?
In house Welding-testing or outside? If it is performed with simple testing instruments, (like tensile testing of spot weld coupons) and if it is routine and repetitive you may gain time from testing with some simple instrument and getting the answer on the spot, so that you may easily reweld and retest.
Simple testing…
What are non instrumented Welding-testing? These are tests that anybody can perform in the shop, and give a measure of understanding and of confidence in the results. It is recommended to perform some sort of these tests just to know for yourself. You should first establish the form and dimensions of the test piece, to reproduce features as similar as possible to those of the real weld, and weld it.
