Abstract

Austenitic stainless steel has superior characteristic in corrosion resistance, but it tends to crack when welded. To prevent the crack during the welding, Cr equivalent can be increased to produce fasa ferit in austenitic metric. Austenitic stainless steel containing minimum 4% of ferit will avoid weld cracking; however, it will decrease the corrosion resistance. The aim of this research is to know the corrosion rate of austenitic stainless steel with different ferit content in the as cast and as weld conditions. The different content of ferit is obtained in two ways. First, in as cast condition it is obtained by choosing 3 different materials with different chemical compound. Cr equivalent and Ni equivalent are calculated so that by using Schaeffer diagram the ferit content in the main metal ( austenitic steel) can be identified that is ferit number 7, 9, and 10.The second way is obtained through the welding process using different electrode for different main metal. By taking 20% of the delusion, austenitic stainless steel containing ferit number 6,8,and 9 is obtained. Corrosion rate, tensile strength, and impact tests are done on these six materials. The findings show that in the same ferit number, as weld stainless steel is more corrosive and the impact strength is much lower than that of as cast. Meanwhile, in the same material(as weld as well as as cast) the bigger the ferit number the more the corrosion and the lower the tensile strength and the impact are.

Abstract

Welding is one of part importing in Manufacture process, because almost all manufacture product always get involve welding process, because of that process and welding result in manufacture process need to pay attention because this will be connected directly with quality of manufacture product. Mean while, as a judgmental in a production for stable in price is possible for using different material and has to weld by using welding process (dissimilar welding), in that hook, this research for knowing fisis characteristic and welding product mechanist between lowest carbon steel with endure corrosion steel by using direct dissimilar welding system and butter.In this research, was conducting welding by using low carbon steel material which have AISI standard 1020 and endure corrosion steel with ISI 304 series. Also AWS E 308 Welding was conducting by using SMAW system along with DC 80, 90 and 100 Ampere current variable. From that tarik tested that highest pull power had been result from welding with butter method and 90 ampere current is 44,79 Kg/mm2 and general result from tarik butter method test is better than direct method because all current variable has result bigger force than butter method. Mean while lowest pull power result on the direct welding with 100 amperes, its 43,3 kg/mm2. Mean while from the hardness result test that hardness distribution on the HAZ area and a good welding kernel result on the welding by using butter method with 90 ampere and direct method with 80 ampere. On the 100 ampere with butter method or hardness direct distribution not good because there are stepess on the hardness graphics that resulted. This point will be result in voltage concentration which is result in descending weld power.

AbstractThe community in Bugel 2 Hamlet, Bugel Village, Panjatan Subdistrict, Kulon Progo Regency, Yogyakarta Special Region Province, is a beach sand farmer who cultivates chilli, watermelon, melon and others. Every day they need water to watering the plants. Water is obtained by using a gasoline engine for water pump so it increases the cost of expenditure. Through a development program for sustainable education (ESD). The community was introduced to alternative energy, namely windmills as a driver of water pumps. Windmills are expected to be an alternative to change the water pump of gasoline engine. Windmill construction consists a stake was made of 4 m high cast concrete. Windmill functions to change the kinetic energy of wind into rotational motion, through eccentric wheels or crankshaft rotational motion is converted into translation. The translation motion moves the up and down pulling rod of the piston pump to pump water from the well to the surface. The piston pump was made using PVC pipe material. The capacity of the pump made from PVC pipe material is 4.5 litres/minute. While the minimum wind speed to produce this capacity is 4 meters/second.The involvement of making windmills includes lecturers, students and the community as a form of ESD-based learning. The number of windmills made as educational media made as many as 6 pieces scattered in several wells of residents. In terms of the social aspects of the community, pump technology and windmills are not very complicated technologies, it is easily mastered, socialization to the community as users. The technology of windmill is very helpful for the community. Keywords: windmills, water pumps, wells AbstrakMasyarakat di Dusun Bugel 2, Kelurahan Bugel, Kecamatan Panjatan, Kabupaten Kulon Progo DIY, merupakan petani lahan pasir pantai dengan budidaya tanaman cabai, buah semangka, melon dan lainnya.

Abstract

Welding is joining two or more metal parts by heating the metal until it melts and then adding material (electrode) to fuse like a complete object. The welding process on steel causes the metal around the weld area to experience changes in the thermal cycle, so before welding, providing preheating treatment with temperatures of 100°C, 150°C, and 200°C, then on the surface of the metal and to increase its hardness, a further process is carried out namely the hard facing process.   Hardfacing is a process where a harder material is applied to a parent material through welding. The hard-facing method is carried out by melting the HV-600 electrode wire on a plate until it obtains the desired thickness, resulting in a harder microstructural change on the metal surface. This research aims to determine the effect of preheating temperatures of 100°C, 150°C, and 200°C on the physical and mechanical properties of AISI 1040 steel material which is heat faced with HV – 600 electrodes in the Shield Metal Arch Welding process. The tests carried out in the research for physical properties were microstructure, and for mechanical properties were hardness and wear. The results of microstructure research at preheating temperatures of 100°C, 150°C, and 200°C, the magnitudes are 79.52%, 72.01%, and 68.56% respectively and the hardness values are 79.6 HRC, and 78 HRC respectively. and 75 HRC while the wear values are 0.0000587 m3/kg.m, 0.0000873 m3/kg.m and 0.0000917 m3/kg.m. From the results of this research, the optimum hardness and wear values are hard-facing with the preheating temperature of 100°C.
