Abstract

Generally, this thesis is discussed about how to solve the problem of undercutting and porosity in arc welding by using the TRIZ Methodology. TRIZ is one of the methods to solve the problems in the market. A theory designed for solving problem that has a presence of contradiction and having its own inventive problem solving tools. Initially in this report, the major problems that occur in process arc welding are determined. Secondly, the causes that affect the welding problem to occur are discovered before the TRIZ is implemented to solve the problems. Basically, the 39 Engineering Parameters and 40 Principles tool which are available in TRIZ are used to solve arc welding problems. Although the principles are developed long time ago and it can be represented as the solution for today’s problems to show the relevancy of the theory that is general in idea but deep in meaning. Based on the proposed solution from guidance of principle 04 to solve the undercut problem, the result is exposed in Figure 4.14. The undercut problem can be reduced or remove by using proposed solution. Besides, Table 4.12 shows that frequent occurrences of porosity can be reduced based on the proposed solution which guidance from principle 13. A lot of suggestions to solve the arc welding problems are proposed and presented in this report.
