Analisa Kekuatan Tarik pada Sambungan Las Baterai terhadap Kekuatan Arus Listrik Baterai

Abstract

Research analysis of the tensile strength of the weld on the battery to power an electric current battery has been done. The goal is to determine the tensile strength of welded joints using welding batteries with a variable flow battery, the thickness and diameter of the test material. Research methodology, including: (1) assemble welding battery (battery consists of 3 pieces) with the desired total current is 60 A, 80 A and 120 A, (2) arranging charging the battery and welding handle bar positive and negative, (3 ) welding on iron plate with thickness 4mm, 6mm and 8 mm with a current 60 A, 80 A and 120 A, (4) on an iron rod diameter 8mm, 10mm, and 12 mm with a current 60 A, 80 A and 120 A. The results showed the shape of specimens of iron, welding tools and strong currents thickness / diameter significantly influence the tensile specimens welded with welding tools batteries. The best treatment to iron rod the current round is 60 A at 8 mm diameter tensile yield amounted to 11.65 kg/mm2. The best treatment for the current iron plate is 80 A at 8 mm thick plate produce a tensile strength of 38.2 kg/mm2. From the calculation of economic, investment and operational costs-making tools, welding batteries cheaper than welding inventer and welding dynamo. However, welding batteries can not be regulated the size of the battery current.
