The ranges of qualification are specified in Tables 4 and 5.對接焊焊工資格測試是以材料厚度和外部管子直徑為基礎的。表4和表5說明了考核范圍。NOTE It is not intended that material thickness or outside pipe diameters should be measured precisely but rather the general philosophy behind the values given in Tables 4 and 5 should be applied.注意，并不是指須精確測量材料厚度外部管子直徑，而是應使用表4和5所示值背后的一般原理。For fillet welds the range of qualification for material thickness is specified in Table 6.角焊的考核范圍，表6中規(guī)定了材料厚度。In the case of branch welding the material thickness criteria to which Table 4 applies and the outside pipe diameter criteria to which Table 5 applies is as follows:在分支焊接的情況下，表4適用的材料厚度標準和表5適用的外部管子直徑標準如下：－ Set on: The material thickness and outside pipe diameter of the branch。－Set in or set through: The material thickness of the main pipe or shell and the outside pipe diameter of the branch.定位：分支的材料厚度和外部管子直徑； 焊進或焊入：主管或外殼的材料厚度，以及分支的外部管子直徑。For test pieces of different outside pipe diameters and material thicknesses, the welder is qualified for:不同外部管子直徑和材料厚度的測試件，考核焊工：1) the thinnest and thickest material thickness qualified in accordance with Table 4。1) 按表4，能勝任最薄和最厚的材料；2) the smallest and largest outside pipe diameter qualified in accordance with Table 5.2) 按表5，能勝任最小和最大的外部管子直徑。Table 4 — Range of qualification of material thickness and weld metal thickness (multi process) of test表4測試的材料厚度和焊接金屬厚度的考核范圍（多工藝） Dimension in millimetres尺寸以毫米計Thicknessa厚度atRange of qualification考核范圍t3t to 到2xtb3163。t163。12t to 到2xtct12179。5a For multi processes, s1 and s2 of Table 1 apply.a用于多工藝，表1的s1 和 s2適用。b For oxyacetylene welding (311): t to 1,5 180。 tb用于氧炔焊接（311）：t 至 1,5 180。 tc For oxyacetylene welding (311): 3 mm to 1,5 tc 用于氧炔焊接（311）：3 mm to 1,5tTable 5 — Range of qualification for outside pipe diameter a表5外部管子直徑a考核范圍 Dimension in millimetres 尺寸以毫米計Outside pipe diameter of test piece測試件的外部管子直徑DRange of qualification考核范圍D163。25D to 至2xDD25179。 (25 mm min.)（最低25mm）a For structural hollow sections, D is the dimension of the smaller side.a 對于結構空心的部分，D是較小一端的尺寸。Table 6 — Range of qualification of material thickness of test piece for fillet weldsa表6角焊測試件材料厚度的考核范圍aDimension in millimetres 尺寸以毫米計Material thickness of test piece測試件的材料厚度tRange of qualification考核范圍t 3t to 至 3t 179。 3179。 3a See also Table 9.a 也見表9. Welding positions 焊接位置The range of qualification for each welding position is given in Table 7. The welding positions and symbols refer to EN ISO 6947. ISO 6947。The test pieces shall be welded in accordance with the nominal angles of the welding positions according to EN ISO 6947.測試件應按EN ISO 6947，按焊接位置的標稱角度進行焊接。The welding positions JL045 and HL045 for pipes qualify for all pipe angles.管子的焊接位置JL045 和 HL045可考核所有管子角度。Welding two pipes with the same outside pipe diameter, one in welding position PF and one in welding position PC, also covers the range of qualification of a pipe welded in welding position HL045.焊接兩個相同外部管子直徑的管子，一個焊接位置PF，另一個焊接位置PC，還涉及焊接于位置HL045的考核范圍。Welding two pipes with the same outside pipe diameter, one in welding position PG and one in welding position PC, also covers the range of qualification of a pipe welded in welding position JL045. 焊接兩個相同外部管子直徑的管子，一個焊接位置PG，另一個焊接位置PC，還涉及焊接于位置JL045的考核范圍。Outside pipe diameters D 179。 150 mm can be welded in two welding positions (PF or PG 2/3 of circumference, PC 1/3 of circumference) using only one test piece.外部管子直徑D 179。 150 mm可焊接于兩個焊接位置（PF或PG 2/3周長，PC 1/3周長），只使用一個測試件。Table 7 — Range of qualification for welding positions表7—焊接位置的考核范圍Weldingpositionof testpiece測試件的焊接位置Range of qualificationa考核范圍aPA PBb PC PDb PE PF (Plate)（平板）PF (Pipe) (管子)PG (Plate) (平板)PG (Pipe)（管子）HL045 JL045PAX X– – – – – – – – – PBb X X– – – –
