Layers of Fe-Cr-C Hard facing material containing various amounts of chromium were deposited on mild steel base metal. Optical Microscope (OM), Scanning Electron Microscope (SCM) and X-ray diffraction (XRD) were used to investigate the effect of chromium content of micro structural characteristics of Fe-Cr-C hard facing layers. The M7C3 carbide refinement mechanism exists on base metal. The exp...

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)....

The papers for investigation this were considered 2010 date 2021. A total 20 research...

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...

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...
