What is the national standard for TIG welding of tungsten stainless steel?
There are three inspection standards for any welding:1, surface examination, the main test whether there are edges, surface cracks, surface pores and slag inclusion;2, nondestructive testing (such as RT, UT, MT) detection is mainly superficial and internal as well as the root of all welding defects, such as porosity, crack, internal slag, burn, incomplete penetration defects etc.;3 、 final pressure test (strength, pressure and tight pressure), whether or not the weld is leaking.Inspection standards are mainly based on design documents and standards and specifications: such as the transmission of toxic, harmful, flammable medium pipes, welding requirements nondestructive testing, I level or II level qualified, standards are different
New standard YB/T5092-2005, old standard YB/T5092-1996.This standard specifies the classification, grades, sizes, shapes, technical requirements, test methods, inspection rules, packaging, marks and quality certificates of stainless steel wire used for welding.This standard applies to the production of welding wire welding core, arc welding, submerged arc welding, electroslag welding with stainless steel wire welding.
New standard YB/T5092-2005 this is
