摘要

This test program is intended for the approval of automatic or semi-automatic, single-electrode submerged arc welding. Provisions are made for the testing of weld metal deposited by multi-run and two-run (one pass each side) techniques. For YQ Grades automatic welding, a multi-run technique is contemplated. Application for high heat input process, such as automatic welding two-run technique, may be considered under 2-A2-1/3.5 and approval by a technical office. Where a manufacturer states that a particular wire-flux combination is suitable for welding with both techniques, both series of tests are to be carried out. The suffix T, M, or TM will be added to the grade to indicate two-run technique, multi-run technique, or both techniques, respectively.
