摘要

其中一个铁路设施采用不锈钢作为主要建筑材料。不锈钢材料的连接方法，尤其是应用最广泛的是SMAW焊接技术。本研究的目的是确定不锈钢304材料的SMAW焊接接头的抗拉强度在填充材料的棒材直径的变化和直流逆变电焊机电流的变化。棒状填料作为填料的直径有1mm、2mm和3mm。电焊机直流逆变器的电流变化量为70a、100a、120a。结果表明:在目前的电焊逆变器上，304不锈钢焊接接头的抗拉强度最高，平均拉应力为34.48 MPa;线缆采用120a，填充棒直径2mm。当电焊逆变器电流为70a，焊条填料直径为3mm时，304不锈钢材料的焊接接头抗拉强度最低，平均抗拉应力为17.01 MPa。关键词:SMAW焊接，填料，电流，不锈钢

Pengaruh Variasi Diameter Filler Dan Kuat Arus Terhadap Kekuatan Tarik Hasil Pengelasan SMAW Material Stainless Steel 304

One of the railway facilities uses stainless steel as the main construction material. The method of joining stainless steel materials, especially the most widely used is the SMAW welding technique. The purpose of this study was to determine the tensile strength of SMAW welding joints on stainless steel 304 material with variations in diameter of rod filler as filler material an d variations in current from DC inverter electric welding machine. The diameter of rod filler as filler material is 1 mm, 2 mm and 3 mm. The variation of the current of the DC inverter of the electric welding machine is 70 A, 100 A and 120 A. The results show the highest tensile strength of the 304 stainless steel welded connection with an average tensile stress of 34.48 MPa on the current electric welding inverter. 120 A is used and the diameter of the rod filler is 2 mm. And the tensile strength of the welding connection of the 304 stainless steel material is the lowest with an average tensile stress of 17.01 MPa at the electric welding inverter current used is 70 A and the diameter of the rod filler is 3 mm.Keyword: SMAW welding, filler, current and stainless steel
