Abstract

Penelitian ini meliputii analisa efek thermal yang menganalisa pengaruh panas yang terjadi pada saat proses pengelasan FCAW pada pelat baja EH 36 yang mengakibatkan deformasi. Deformasi adala perubahan stuktur baja yang di sebabkan poses pemanasan,peleburan lokal dan pendinginan terhadap material plat baja sehingga terjadi penyusutan dan pemuaian pada material baja. Penelitian ini di lakukan dengn metode kuantitatif dengan menganalisa data yang menghasilkan efek thermal akibat pengelasan FCAW pada pelat EH 36 stool support. Tujuan dari penelitian ini ialah untuk mengetahui seberapa besar deformasi yang terjadi pada pengelasan FCAW dengan variasi posisi pengelasan dan ketebalan plate.hasil dari penelitian ini  didapatkan bahwa pada  peroses fit up  sambungan but joint posisi pengelasan 3G rata rata deformasi yang terjadi sebesar 5 mm, setelah proses pengelasan but joint posisi pengelasan 3G didapatkan hasil deformasi rata rata sebesar 8,25mm. Pada  peroses fit up sambungan filet posisi pengelasan 2G deformasi yang terjadi sebesar 2 mm. setelah proses pengelasan deformasi yang terjadi sebesar 2 mm This Research covered a thermal effect analysis that analyzes the effect of heat that occurs during the FCAW welding process on EH 36 steel plate which causes deformation. Deformation is a change in the steel structure which is caused by the process of heating, local melting and cooling of the steel plate material so that there is shrinkage and expansion of the steel material. This research was conducted with a quantitative method by analyzing the data that produces a thermal effect due to FCAW welding on the EH 36 stool support plate. The purpose of this study is to determine how much deformation occurs in FCAW welding with variations in welding position and plate thickness. The results of this study show that in the fit-up process of the joint butt joint, the 3G welding position average deformation is 5 mm, after processing. But joint welding with 3G welding positions obtained an average deformation of 8.25mm. In the fit-up process of the filet joint, the welding position was 2G, the deformation was 2 mm. after the welding process the deformation that occurs is 2 mm  
这项研究分析了热效应,分析了FCAW焊接对钢板EH 36的影响,导致变形。变形是一种钢结构的改变,它会导致局部冶炼和冷却钢板材料,导致钢材收缩和膨胀。该研究采用定量方法分析分析数据,这些数据产生FCAW焊接在EH 36罩支撑板上的热效果。本研究的目的是确定FCAW焊缝中砂浆的变形程度,其焊接位置和厚度的变化。这项研究的结果是,3G焊接位置的连接3G焊接平均变形为5毫米,焊接3G焊接工艺完成后,平均变形为8.25mm。peroses健康向上的菲力位置焊接2G连接2毫米大小发生了变形。焊接变形过程发生之后2毫米大小的这个研究覆盖a热力效应分析那效应》analyzes热那occurs during the FCAW焊接公司的过程在钢铁板哪种敢死队deformation呃36。变形是一种改变,其结构是由一系列的加热、局部融化和冷却的钢料引起的,因此在这种材料中存在了微小的收缩和扩展的钢铁材料。这项研究的目的是分析产生热效应的数据,以减少对36个线轴支撑的热量效应。这项研究的目的是确定,FCAW中存在对等变量的偏移。这项研究的结果显示,在关节关节的处理过程中,3G的平均分配是5毫米,经过处理。但3G焊工平均结果为8.25毫米。在处理filet合并的过程中,焊接的位置是2G,减减是2毫米
