Welding fumes are common ambient air pollutants in manufacturing facilities, and have been shown to have deleterious effects on human health. An experimental effort is conducted to study the formation and composition of respirable fumes from a SMAW process. The responses examined are the fume particle size distribution (mean diameter) and formation rate (particle number and mass concentration)....

Selecting a process for welding large scale equipment on site demands special expertise due to the numerous variables be considered. This paper is aims applying decision support methodology selection of 16000 cubic meter storage tank welded site. Five processes are chosen select from, namely, Gas Metal Arc Welding (GMAW), Shielded (SMAW), Submerged (SAW), Flux Cord (FCAW) and Tungsten (GTAW). T...

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 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...

Shielded Metal Arc Welding (SMAW), an arc welding process, is widely used in applications. In practice, SMAW applied to the process on hollow square pipe. Performance expected from this tensile strength of weld joint. The influenced by parameters which have possibility for optimization become ‘robust’. Robust a design less sensitive effect uncertain quantities or noise factors. Taguchi method m...

The prediction of the weld bead geometry parameters is an important aspect welding processes due to it related strength welded joint. This research focuses on using statistical design techniques and a deep learning neural network predict shape shielded metal arc (SMAW), inert gas (MIG), tungsten (TIG) processes. With techniques, experiments were carried out obtain data for generating regression...

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...

In industries and research organizations most widely used welding methods are shield metal arc welding (SMAW), gas metal arc welding (GMAW), gas tungsten arc welding (GTAW) and submerged arc welding (SAW). The SAW process is often preferred because it offers high production rate, high melting efficiency, ease of automation and low operator skill requirement. This review will be very helpful for...

Welding is a very important part of the development and growth industry because it has role in engineering, reparation, construction. Shielded Metal Arc (SMAW) or conventional arc welding process particularly dominant structural joints, pressure vessels maintenance repair work. In welding, different metals are joined economically at much faster rate as compared with other fabrication processes ...
