shielded metal arc welding an overview ScienceDirect

Mar 18, 2013 · Shielded metal arc welding (SMAW) is the simplest, least expensive, and mostly widely used arc welding process (Figure 2).It is often referred to as ‘stick welding’ or manual metal arc welding. This process produces coalescence of metals by heating them with an arc between a covered metal electrode and the base metal work piece.

flux cored arc welding an overview ScienceDirect Topics

Flux cored arc welding (FCAW) is a more economical alternative to shielded metal arc welding (SMAW), since it is a continuous wire process and good, effective deposition rates can be achieved as a result of the inherently high duty cycle. The process also lends itself readily to mechanization.

Effect of welding thermal cycles on the heat affected zone

The X65 (a) i.e. the seamless pipe was showing a complete loss of toughness when subjected to the single, double and triple thermal cycles, while the X65 (b), which is a TMCP material was showing excellent toughness in most cases when subjected to the same thermal cycles at

Complying with NACE Hardness Requirements TWI

Introduction. Carbon steels in service in the offshore and oil refinery industries are susceptible to a cracking mechanism known as sulfide stress cracking (SSC) or hydrogen stress cracking (HSC) when in sour service, ie when hydrogen sulfide (H 2 S) is present in the process fluid. Although the cracking is described as stress cracking, the main problem is the hardness of the parent metal

Influence of Inclusions on Strength and Toughness of X70

In this paper, SEM, EPMA, and micro shear experimental method were applied to analyse the structure, inclusion morphology and composition, micro area strength and toughness of the X70 pipeline steel girth weld joint. The results show that inclusions are mainly nonmetallic oxides, sulfides and calcium compounds. The length of inclusions can be up to 1mm, which have substantially reduced the
