Checking welds
WebSelecting a welding electrode for joining is typically done by identifying the mechanical properties (tensile, yield, ductility and impact strength) of the steel you are welding, and selecting a filler material that duplicates those properties. Hardfacing electrodes, in contrast, are very highly alloyed electrodes. This is what makes them so hard. Webiv) To check whether shop/field welding being executed is in conformity with the relevant specifications and codes of practice.
