Describe fusion as it relates to welding operations.
Explanation of Solution
Fusion welding refers to a generic term for welding procedures which depends on melting to join materials having similar melting points as well as compositions. Owing to the high-temperature phase transitions inherent to such procedures, a heat-affected zone gets formed in the material though a few techniques such as beam welding at times lessen the effect by introducing comparatively less heat into the workpiece.

- When steel is joined using arc welding, only the liquid fusion zone must be protected by a gas or flux. However, when titanium is welded, both the front and back sides of the welded metal must be protected. Why must these extra pre-cautions be taken when joining titanium?arrow_forwardWhat problems can occur to stainless steel as it is allowed to form carbide precipitation during welding?arrow_forwardThrough illustrations explain the process of TIG Welding.arrow_forward
