Abstract:

Laser welding of metals and alloys is extensively used in industry due to its advantages of controlled heating, narrow weld bead, low heat affected zone (HAZ) and its ability to weld a wide range of metals and dissimilar metals. Laser welding of dissimilar metals such as carbon steels and stainless steel is still a challenging task, particularly due to the formation of brittle phases in the weld, martensitic formation in the HAZ and solidification cracking in the fusion zone. These issues can significantly deteriorate the strength of the welded joint. The aim of this work is to investigate the

Abstract:

Plain C-Mn steels such as SA-516 Grade 65 are used as steam lines to transport high temperature steam under pressure. Plain carbon steels that are in service at elevated temperatures (typically 400-450°C) for prolonged periods of time (typically in excess of 20 years) may experience an undesirable microstructural change in the form of secondary graphitization. Secondary graphitization of carbon steels is classically defined as the decomposition of cementite into carbon (present as the graphite phase) and iron (ferrite). Many cases have been documented where the decomposition reaction occurs mo

Abstract:

The majority of spot welds in a wide range of sheet metal products e.g. automotive body in white structures and general engineering applications involve the joining of two or more dissimilar sheet thickness. Research to date has concentrated on the welding of two similar thicknesses.

Abstract:

CMT+P welding is less susceptible to hot cracking than the MAG welding process due to use of low heat input properties. Solidification cracking was found in all weld specimens that had greater 0.39KJ/mm heat inputs. Cracking occurs because of the contraction stresses generates during cooling. Hydrogen cracking is found in HAZ with low heat input parameters, this type of cracking occurred because of very rapid cooling and therefore not enough time to allow the hydrogen to dissipate from the specimen. To eliminate this type of cracking the experiment could be repeated by adding heating during we

Laser welding, unlike conventional arc or gas welding, can be effectively utilised to produce high quality, clean and tough welds in high carbon steels. Results of welding high carbon steel are presented. The weld characteristics related to the fast cooling rate were critically evaluated and methods to reduce the rate of cooling were developed. The grain size produced in the fusion and narrow heat affected zones significantly affected the mechanical properties of the welded joint. Three lasers were used: Nd:YAG, CO2 and a high power laser diode (HPDL). The investigations were carried out using

The welding tool is made of tungsten carbide with a diameter of 20 mm, and a mild steel rod is embedded within the ring of tungsten carbide, so that they have the same end plane. The load cell and the thermocouple are used to measure the axial load and the temperature rise, respectively. The effect of feeding speed on the faying surface and the maximum failure load is investigated at

It was found that both the weldments revealed the coarse grain structure in low carbon steel HAZ and 304 HAZ and the sensitization around 304 HAZ. Moreover, the carbon migrated from the low carbon steel base metal to the higher chromium weld metal side and formed chromi

The material used is carbon steel because carbon steel is widely used in the industry, especially in the shipping industry. This experiment uses the Gas Tungsten Arc Welding (GTAW) process. GTAW Welding or more popularly called Tungsten Inert Gas (TIG) is one type of electric arc welding with gas guard. To produce an electric arc, an unused electrode is made of tungsten or alloyed metal which has

The temperatures between the steel sheet of thickness 2 mm and the aluminum alloy of 5 mm were measured during the FSSW process using K-type thermocouples. Results showed that the maximum interface temperature could achieve about 740°C using either the assembled-type or plain tools, but the temperature rise rate
