Many utilities around the world have been discovering abnormal or aberrant P91 base and weld metal microstructures in their plants, leading to, or with a potential to lead to, early cracking and ...

Metal segregation is a common phenomenon in the welding process, which refers to the inhomogeneous chemical composition distribution in the metal alloy. Some scholars have studied the influence of ...

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.

The Keygree TIG205PACDC to 630PACDC series transforms welding from a craftsman-dependent process into a programmable, ...

Regular carbon steel welding is dominated by the standard ER70S wire. Since it’s the primary option, filler metal selection ...

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 ...
