t1for welding process 2:t = t2according to Table 4t = t1 + t2welding process 1only for welding ofthe root area5.3 Product typeThe qualification test shall be carried out on plate or pipe. The following criteria are applicable:a) welds in pipes, outside pipe diameter D > 25 mm, cover welds in plates;b) welds in plates cover welds in pipe:¾ of outside pipe diameter D ³ 150 mm, for welding positions PA, PB and PC;¾ of outside pipe diameter D ³ 500 mm, for all welding positions.5.4 Type of weldThe qualification test shall be carried out as butt or fillet weld. The following criteria are applicable:a) butt welds cover butt welds in any type of joint except branch connections (see also 5.4 c));b) in cases where the majority of work is fillet welding, the welder shall also be qualified by an appropriate filletwelding test; in cases where the majority of work is butt welding, butt welds qualify fillet welds;c) butt welds in pipes without backing qualify branch connections with an angle ³ 60° and the same range ofqualification as in Tables 1 to 8. For a branch weld the range of qualification is based on the outside pipediameter of the branch;d) for applications where the type of weld cannot be qualified by means of either a butt or fillet weld test then aspecific test piece should be used to qualify the welder, e.g. branch connection.

The welding positions and symbols refer toEN ISO 6947.The test pieces shall be welded in accordance with the nominal angles of the welding positions according toEN ISO 6947.The welding positions J-L045 and H-L045 for pipes qualify for all pipe angles.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 H-L045.Welding two pipes with the same outside pipe diameter, one in welding position PG and one in welding positionPC, also covers the range of qualification of a pipe welded in welding position J-L045.Outside pipe diameters D ³ 150 mm can be welded in two welding positions (PF or PG 2/3 of circumference, PC1/3 of circumference) using only one test piece.
