The first and second level welds must pass the inspection of flaw detection, and shall meet the design requirements and the provisions of the construction and acceptance specifications, and check the weld detection report.2. Grade I and ii welds shall not have cracks, welds, burn-through, arc pits and other defects.The second-level welds shall not have defects such as surface pores, slag inclusion, arc pits, cracks, arc abrasions, etc., and the first-level welds shall not have defects such as undercut or incomplete welding.3. Even appearance of welding seam, smooth transition between welding bead and base metal, and clean welding slag and spatter.Alaska Pipeline Construction Welding:First-class welding seam is not allowed;The allowable diameter for each 50mm length of third-level weld is less than or equal to 0.4t.And 2 stomata ≤3mm, stomatal spacing ≤6 times of aperture. Second-level welding seam: edging depth ≤0.05t and ≤0.5mm, continuous length ≤100mm, and the overall length of edging on both sides ≤10% of the welding seam length.In the technical sense, a standard is a uniform agreement issued in the form of documents containing technical specifications or other precise criteria that can be used to define rules, guidelines or characteristics for activities and their results within a certain scope, with the purpose of ensuring that materials, products, processes and services meet the needs.In general, standard documents are developed through a consultative process and approved by a recognized body.
