Welding Of Dissimilar Metal Joint. SomeDifferent materials are joined by using a suitable filler material in between the two. The electron beam welding process has several advantages for welding dissimilar metals.
A number of methods are there to join the material having dissimilar properties. Welded or brazed joints must be used. Ultrasonic welding is also used for welding dissimilar metals since very little heat is developed at the weld joint.
To avoid undue stressing the weldmetalshouldifpossible have an expansion coefficient intermediate between the two parent alloys ie providing a buttering layer Figure 4.
The electron beam welding process has several advantages for welding dissimilar metals. This higher ferrite content can minimize weld dilution and prevent weld cracking. The results of the survey abridged are briefly summarized in Table 1 and the reader is urged to review the entire survey for a complete picture. The electron beam welding process has several advantages for welding dissimilar metals.
