This Document replaced NB/T 47018.6-2011 Technical Permission of Welding Materials for

Pressure Equipment - Part 6: Bare Aluminum and Aluminum-Alloy Welding Electrodes and

Rods. Compared with NB/T 47018.6-2011, the major technical changes of this Document are

as follows besides the structural adjustments and editorial modifications:

a) Deleted the relevant contents on model classification and model compilation method (see

Clause 3 of the 2011 Edition);

b) Modify the model representation method of aluminum welding wire and filler wire

according to GB/T 10858; delete the uncommon aluminum alloy welding wires SA14009,

SA14011, SA14010, SA14145, SA14643, SA15654; and add SA15087 (see Table 1 of

this Edition; Table 1 of the 2011 Edition);

c) Delete the table of chemical composition requirements for aluminum welding wire and

filler wire; and implemented it according to GB/T 10858 (see 3.2.1 of this Edition; 4.2.1

and Table 2 of the 2011 Edition);

d) Add barreled welding wire and specific requirements (see 3.3.2 of this Edition);

e) Add relaxation diameter and warpage and specific inspection requirements (see 3.5 of this

Edition);

f) Change the designation of the parent materials used for the test (see Table 3 of this Edition;

Table 3 of the 2011 Edition);
