ASTM 1045 Weldable? - Metal and Metallurgy engineering Jun 08, 2009 · The remaining weld looks like it was welded a little cold. It looks like the weld is still there and it failed at the toe/HAZ. If you look at toe between 12 and 1 o'clock you can see the weld looks to have been under-filled or undercut the base metal. Also, in this area the weld has convexity this is an indication of the volts being to low.

In many cases the manufacturer that uses ASTM steels will find that it's not necessary for the weld to match the mechanical properties of the steel, (its often better for the weld to have more ductility than the plate) and therefore low hydrogen, highly ductile SMAW E7018 / E70S-3-6 MIG wires or E7XT-X flux cored electrodes are used.

Heat Affected Zone and Weld Metal Properties in Welding Oct 01, 2016 · Heat affected zone. During the selection of steels, the characteristics of the HAZ are more important than the weld metal. This is since the metallurgical and mechanical properties of the HAZ are directly linked to the selected steel. However, these properties can be adjusted by welding parameters and post weld heat treatment (PWHT).
