Analysis on the Industrial Applications of Flux Cored Arc Welding on an International Scale

Abstract

The study focuses on analyzing the industrial applications done by international companies using Flux Cored Arc Welding, considering the factors of welding quality, productivity, economy, practices, problem and solutions. With the aim to determine the techniques done by companies around the world to prevent complications experienced upon welding, the researchers surveyed 43 international companies from different regions of the world. The responses are presented into pie charts and bar graphs that were interpreted into a qualitative analysis. Inferential statistics, specifically one-way Analysis by of Variance (ANOVA) and one-sample T Test in hypothesis testing with the means of statistical software Minitab and IBM SPSS Statistics respectively, are conducted to distinguish the influence of variables to the key words of the study. The significance level of most of the test variable in one-way ANOVA were greater than the 95% confidence interval, confirming the similarity of results given by the companies. FCAW is still one of the most used welding methods by the industrial companies internationally due to its ease of use. Welding problems are encountered despite of this and having welders training. Additionally, the researchers obtained sample mean of competitiveness in terms of product quality and performance level, having 4.6 for domestic and 4.33 for international (5 being the highest level). With the test value of 4.46, it showed no significant differences between domestic and international, meaning that the industrial companies believe that their product quality and performance level are at a proficient competency in domestic and international market.
