Due to its exceptional corrosion resistance and high strength, DSS is the best metal to use in harsh settings such as reactors, petroleum tankers, deep-sea pipelines to transport petroleum material, ...

As with traditional welding techniques, materials are melted in the weld zone, although laser-based techniques use quicker heating and cooling cycles (Figure 1). These rapid thermal cycles are a ...

If the material being welded is a precipitation hardened aluminum-copper alloy, the heat affected zone close to the weld melt region will be raised above the overageing temperature. The top diagram ...

Rajeev Ranjan in his thesis investigates the influence of low-frequency vibration-assisted welding on the mechanical properties and microstructure of shielded metal arc welded mild steel plates.

Friction stir welding joins previously unweldable materials. Friction stir welding, a relatively new process, is having a tremendous impact on welding dissimilar alloys. It was developed in 1991 by ...

When materials are joined by a welding process they are locally melted, re-solidify, and cool down to room temperature. The joining of two steel plates (pearlite) by welding is shown in the top ...
