For welded links, after checking batch materials by spectograph to ensure qualified raw material, we make welding quality checks and bend test to make sure the welded joint is of right quality. During bend test, three test piece samples are chosen and tested, they are bent in a shock free manner in the bend test equipment. Test pieces taken from the links to be tested will contain a central weld and will have a length of 5 times the link diameter.
