By Materials & Welding
Dear all
does anybody have expriences or interpretations about
QW 404.10 & 404.27(the alloy content of the weld metal is largely dependent(how can assess) upon the composition of the flux used, any change in any part of the welding procedure which would result in the important alloying elements in the weld)
 
QW 404.24:10% VOLUME IN TOTAL LENTGH OR NOT?
