Abstract: This study aimed to analyze and optimize deposition welding parameters using a pulsed tubular wire process (FCAW - Flux Cored Arc Welding), where the influence variables adopted were average current, pulsation frequency, speed contact-tip-workpiece distance, with each variable being tested at three different levels. The geometric characteristics evaluated, that is, response variables,...

Selecting a process for welding large scale equipment on site demands special expertise due to the numerous variables be considered. This paper is aims applying decision support methodology selection of 16000 cubic meter storage tank welded site. Five processes are chosen select from, namely, Gas Metal Arc Welding (GMAW), Shielded (SMAW), Submerged (SAW), Flux Cord (FCAW) and Tungsten (GTAW). T...

HUNDREDS OF THOUSANDS of people work in welding, cutting and brazing. It is estimated that welders compose 1 to 2% of the U.S. working population, including a significant segment of the aging workforce. According to OSHA’s Christine Petitti, the most commonly used welding processes are: 1) Flux-cored arc welding (FCAW). This process uses an arc between a continuous filler metal electrode and th...
