Welding is a fabrication or sculptural process that joins materials, usually metals or thermoplastics, by causing coalescence. This is often done by melting the workpieces and adding a filler material to form a pool of molten material (the weld pool) that cools to become a strong joint, with pressure sometimes used in conjunction with heat, or by itself, to produce the weld.

Welding is the process of permanently joining two or more metal parts, by melting both materials. The molten materials quickly cool, and the two metals are permanently bonded. Spot welding and seam welding are two very popular methods used for sheet metal parts.

Spot welding is primarily used for joining parts that normally upto 3 mm (0.125 in) thickness.

Similar to Soldering and Desoldering (removing the Electronic components viz Transistors, Integrated Circuits etc) process is there also a Dewelding Process ?

Since the Two and more metals are permanently bonded by the welding process is there any way again to separate the same ?. Can dewelding process help in the same ?

As accuracy, precision is required in welding process, it may happen that the welding process either by human intervention or by an automated machine may not give the best results i.e. weld (alloy).

In this case, what are the alternatives ?.

Do we have to try another two metals viz steel, iron etc for welding process ? This could be similar or dissimilar metals.

There are different types of welding viz spot, arc, oxyfuel gas etc, maybe dewelding process may work in some of the welding processes.

Do you feel dewelding process can give us the original metal parts back ?
Do you feel the only alternative if weld is not properly done is to throw
the weld ?
Do you feel dewelding process may not work with dissimilar metals but might work with similar metals ?

Note : The Dewelding process may or may not work with all types of welding process.

Can the Welding, Cutting Process be made Fully Automated ? i.e. without Human Intervention.
