Desa Burengan adalah desa yang terletak di kecamatan pesantren kota Kediri. Masyarakatnya sebagian besar bermata pencaharian bercocok tanam dan berdagang. Saat ini banyak para pemuda membutuhkan lapangan pekerjaan ketrampilan untuk berwiraswasta. Inilah melatar belakangi dari kegiatan pengabdian ini, yaitu sangat terbatasnya minimnya kelurahan Burengan. Tujuan memberikan keterampilan kedepan bi...

The focus of this work is to design parameters for shielded metal arc welding to ensure continuous and leak proof joints. To achieve the object an attempt has been made to selected important welding parameters. The selected welding parameters are welding current, welding speed, electrode angle and electrode angle. The selection is purely based on field expert’s suggestions, literature Survey an...

The objective of this laboratory study was to identify and measure manganese (Mn) fractions in chamber-generated welding fumes (WF) and to evaluate and compare the results from a sequential extraction procedure for Mn fractions with that of an acid digestion procedure for measurement of total, elemental Mn. To prepare Mn-containing particulate matter from representative welding processes, a wel...

Residual stresses induced by the welding processes may, in some cases, result significant warping and distortions that can endanger integrity of welded structures. This document reports an investigation process to make a dissimilar T-joint through advanced Finite Element (FE) modelling dedicated laboratory test. The consisted two plates materials, AISI304 S275JR steels, both having thickness 5 ...

The high strength carbon steels such as API X65 is widely used to build the pipelines. In this study, the corrosion behavior welds region of the gas pipeline was studied. For this purpose, Shield Metal Arc Welding (SMAW) was used to evaluate the proposed method. The welding processes were performed with E6010, E6013, and ER70S-6 electrodes as filler metal and welding carried out in 3 passes by ...

This study investigates the effect of increased welding layers welded by SMAW process on distorsion, thickness, microstructure, hardness, and corrosion. The method used in this research is experimental. Low-carbon steel with a size 150x10x10 mm was technique using an HV 450 electrode. Variations are single, double, triple. three variations samples were observed digital camera optical microscope...

This work proposes a new methodology for the detection of discontinuities in the weld bead applied in Shielded Metal Arc Welding (SMAW) processes. The detection system is based on two sensors-a microphone and piezoelectric-that acquire acoustic emissions generated during the welding. The feature vectors extracted from the sensor dataset are used to construct classifier models. The approaches ba...
