  • GMAW(Gas Metal Arc Welding) processes are usually used in industrial side in order to get its high productivity. But those are only adopted in the semi-automated welding equipment because of a lot of welding spatters. Many industrial robot actually percents from being engaged in the welding processes. The welding spatter problem of causes blocking them being a fully automated welding process.This study was carried out to investigate the optimal conditions for minimizing welding spatter generation at GMAW robot. The spatter can be significantly reduced below 2% of welding spatter generation at the following conditions ; First, below 18V at the wire-feed rate 2.0mm/min Second, below 23V at the wire-feed rate 3.6mm/min Third, below 24V at the wire-feed rate 5.5mm/min.

  • This study developed HanScript, which is an educational Hangul programming language, in order to make programs easily and conveniently and applied it to the school fields. To evaluate HanScript, additionally, the researcher divided the properties of educational programming languages into easiness to read, easiness to write and easiness to debug and, based on them, compared HanScript with Visual Basic. According to the result, HanScript was expressed in Korean language style, so was easier to read and debug than Visual Basic. But it was not different from Visual Basic in debugging. Due to fewer libraries compared to Visual Basic, however, it was difficult to implement complex functions using HanScript. In addition, HanScript did not include an editor to edit source codes. Thus, if HanScript is equipped with rich libraries, detailed debugging information and an editor for source code edition, it will be a useful educational programming language.
