Shielded Metal Arc Welding (SMAW) is one of the liquid welding processes (fusion welding) that produces a homogeneous fusion electrode with base metal (base metal), which caused by an electric arc generates high heat to melt and metal). simultaneously protected shielding gas from chemical reaction flux. The depth formed determined input, angle direction. research was conducted at Mechanical Eng...

In this work, the development and validation of a methodology for robotic welding with covered electrodes (SMAW) using a variation of the tool center point (TCP) model is shown. The covered electrode becomes part of the kinematic model of the robot as an additional prismatic joint, whose movement is determined by the electrode consumption or melting rate. This allows programming the trajectory ...

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...

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...

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 ...
