NBT47014 P38 Table 10, items 4 and 5 – could someone help explain this? I can’t understand it
For weld qualification of GMAW on 10mm thickness, what is the range for the base metal and weld thickness?
The root metal coverage thickness is 10–11 mm, while the weld metal coverage thickness is 0–20 mm.
First and foremost, it depends on what type of droplet transfer is used in your GMAW process. . . . In the case of a short-circuit transition with no impact requirements: for the base material, refer to row 4; for the deposited metal, refer to row 5. The coverage thickness of the base material is 1.5–11 mm, while that of the weld metal is 0–11 mm
