Weldability Factors –Base Metal
Some metals melt too easily; e.g., aluminum
Metals with high thermal conductivity transfer heat away from weld, which causes problems; e.g., copper
High thermal expansion and contraction in metal causes distortion problems
Dissimilar metals pose problems in welding when their physical and/or mechanical properties are substantially different
