Fusion welding is a method that makes use of heat to combine or fuse two or more materials into a melting point by heating them. The method may involve the use of filler material, or it may not. … Here is more on what is fusion welding.

Is Spot Welding also known as fusion welding?

Resistance welding is a fusion welding process that requires the application of both heat and pressure to achieve a sound joint. The simplest form of the process is spot welding where the pressure is provided by clamping two or more overlapping sheets between two electrodes (Fig.

What is plasma and fusion welding?

Similar to GTAW (Tig), the plasma arc welding process uses this plasma to transfer an electric arc to a work piece. The metal to be welded is melted by the intense heat of the arc and fuses together. In the plasma welding torch a Tungsten electrode is located within a copper nozzle having a small opening at the tip.
