摘要
PT. Barata印度尼西亚(Persero)法律水资源部门是水机械车间之一,专门从事水机械并支持水资源部门的制造和安装。本次工作坊的重点是水结构的机械工作,如压力管道,阀门和水坝的垃圾架,水坝的闸门和防洪泵。这项研究的题目是“在PT Barata印度尼西亚(Persero)水资源部门使用SMAW焊接工艺的sm400b钢焊接过程中强电流对抗拉强度的影响”。本研究的目的是确定电流强度对抗拉强度的影响,并确定由不符合焊接程序规范(WPS)的电流引起的焊接缺陷。检验方法是先寻找支持文献,然后收集现场资料,再进行数据分析。材料为sm400b钢,焊条为e7016,直径为3.2,采用SMAW焊接。根据已经完成的研究,已知电流越大,抗拉强度值越大,反之亦然,冶金工程与加工技术杂志,第2卷,第0期。2, 2022年2月,pp.39-46 P-ISSN: 2723-6854, E-ISSN: 2798-1037 40电流下,拉伸强度值越小。此外,电流强度必须与WPS匹配。如果焊接电流与WPS不匹配,则会产生焊接缺陷。焊接电流过低会造成凹口、焊接飞溅等形式的焊接缺陷,而焊接电流过高则会造成气孔、熔透不完全等形式的焊接缺陷。关键词:焊接;电流强度;抗拉强度;

PT. Barata Indonesia (Persero) Tegal Water Resources Division is one of the hydromechanical workshops that specializes in hydromechanical and supports the fabrication and installation of the Water Resources Division. This workshop focuses on mechanical work for water structures such as penstock pipes, valves and trashracks in dams, sluice gates in dams and flood control pumps. This research is entitled "Effect of Strong Current on Tensile Strength in SM 400 B Steel Welding Process Using SMAW Welding Process at PT Barata Indonesia (Persero) Water Resources Division-Tegal". The purpose of this study was to determine the effect of current strength on tensile strength and to determine welding defects caused by currents that are not in accordance with the welding procedure specification (WPS).
