        abstract = {This study investigates the effect of wire 
preheating and feed rate on laser beam welding of X
series pipeline steels (API 5L grades such as X52, X65, 
and X70). Experimental analysis revealed that these 
parameters significantly influence weld quality, 
microstructure, and mechanical strength. Preheating 
enhanced fusion, reduced residual stress, and promoted 
finer grain structure across the X-series grades. An 
optimal wire feed rate ensured uniform material 
deposition and improved joint integrity. The results 
demonstrate that precise control of wire preheat and 
feed rate is essential for achieving high-performance 
welds in X-series pipeline applications.},
