hi,
I have to prepare a porosity test acc. to AWS C2.23m/NACE on zinc coating made on steel, but i have a few questions, I will be really grateful if You would like to answer me:
1. Metallograhic samlpe should be made on bend test, which was made on point 3.2.4 ?
1.2. Sample of bend test sample should be similar to 100x50mm/200x1.3mm, but how big is the testing zone ? Full dimentions (100x50/200x1.3) after 180* bending ?
3. Were can i get a% parameter? It described by AWS or customer order?
4. Porosity measurement could me made by graphic analysis on computer?
greets, and thanks for answer!
