Question

Of the following which is a non contact welding process, requires no electrode and is not influenced by the presence of magnetic fields?

A) Gas Metal Arc Welding (GMAW)
B) Resistance Spot Welding (RSW)
C) Laser Beam Welding (LBW)
D) Submerged Arc Welding (SAW)

Answer 1

Laser Beam Welding (LBW) is a non-contact welding process that requires no electrode and is not influenced by the presence of magnetic fields.

Step-by-step explanation:

The non-contact welding process that requires no electrode and is not influenced by the presence of magnetic fields is Laser Beam Welding (LBW). In this process, a laser beam is used to melt and join the metal materials together. The laser beam provides the energy required for welding, without the need for an electrode or direct physical contact.
