Process piping has its own unique requirements and challenges. Welders must adhere to strict codes when welding in these applications, as well as take precautions to avoid potential defects like lack of fusion, porosity, or other weld defects that could compromise the integrity of the completed weld.
As a means to gain a competitive advantage, some welders have chosen to move away from the shielded metal arc welding (SMAW) or gas tungsten arc welding (GTAW) processes common in this industry and convert to wire processes.
Advanced technologies like modified short-circuit GMAW or pulsed gas metal arc welding (GMAW-P), as well as conventional GMAW and flux-cored arc welding (FCAW), can help speed production, ease training, and produce high-quality welds in process pipe applications.
Some welders may find that using a solid or metal-cored wire for the root to cap passes provides the most productivity, while others may require a combination of other processes. Whatever the decision, it is critical to select high-quality filler metals for the job to prevent potential defects and ensure the weld quality and productivity needed to gain a competitive advantage from a wire process.
