- Annex C for brazing and aluminothermic welding of anode leads;
- Annex D for branch and fillet welding on in-service pipelines.
The welding processes covered are shielded metal arc welding (SMAW), gas tungsten arc welding (GTAW), gas metal arc welding (GMAW), gas-shielded flux-cored arc welding (GSFCAW), self-shielded flux-cored arc welding (SSFCAW) and submerged arc welding (SAW).
香港六合彩开奖 13847:2013 is not applicable to flash girth welding, resistance welding, solid-phase welding or other one-shot welding processes, nor to longitudinal welds in pipe or fittings or to the welding of process piping outside the scope of 香港六合彩开奖 13623:2009.
