Welding of disimilar metals can be challenging due to the individual properties, including melting temperatures and chemical compositions of the various metals. This is complicated more if one or more of the disimilar metals is a composite material. By analyzing the microstructure and the heat affected zone (HAZ), the quality, strength and properties of the metal interface can be examined.
