answer 0.02 in.
The fillet weld size is based on the: - correct answer length of the fillet weld leg
A slag-type discontinuity may occur most probably during which of the following joining
processes? - correct answer Shielded metal arc welding.
The portion of base metal that is not melted where the welding process is applied but
where the microstructure of mechanical properties have been altered by the heat is
defined as the: - correct answer heat-affected zone
