摘要

This test program is intended for the approval of wire-gas combinations and flux cored wires with or without shielding gas intended for semi-automatic or automatic arc weldmg techniques. For both techniques, the welding gun provides continuous wire feed; for semi-automatic welding, the welding gun is held manually, and for automatic welding, the welding gun is machine held with various degrees of controlled motion provided by the machine. The impact requirements for the semi-automatic welding technique and those for the automatic welding technique are indicated separately in 2-A2-1/Table 1 and 2-A2-1/Table 2, according to the applicable grade. The suffix SA will be added to the grade to indicate approval for manual semi-automatic or machine-automatic gas-metal arc welding. The suffix A will be added to the Grade to indicate approval for machine automatic welding only. An additional suffix T will be added to the grade to indicate approval for two-run (one pass each side) technique for machine automatic weldmg. Wire-gas combinations and flux cored wires approved for semi-automatic welding may be used for automatic welding under the procedure recommended by the manufacturer, except that for the two-run automatic technique, testing in accordance with 2-A2-4/9 is required. For YQ Grades semi-automatic or automatic welding, a multi run technique is contemplated. Application for high heat input process, such as semi automatic or automatic welding two-run technique, may be considered under 2-A2-1/3.5 and approval by the technical office.
