Photobiological hazards in shielded metal arc welding
Physica Medica, 2023Photobiological hazards caused by artificial optical radiation are assessed for the most commonly used arc welding technique, the SMAW (Shielded Metal Arc Welding), which operates with a hand-held system and is widely used both at occupational and domestic environments, expanding our previous investigation of a robotic arc welding process.The complex ...

Effects of External Magnetic Field on Welding Arc of Shielded Metal Arc Welding. [PDF]
Indian Journal of Applied Research, 2011 The main aim of this study is to show the characteristic changes obtained by the deflection of welding arc in the presence of external magnetic field. The magnetic field has been applied from various orientations upon the weld bead and its effects have been discussed accordingly.

Evaluation of Shielded Metal Arc Welding Consumables for Repair of Weld-Zone Corrosion [PDF]
Canadian Metallurgical Quarterly, 1989 AbstractFive SMAW consumables were evaluated as candidates for repairing weld-zone corrosion in Canadian Coast Guard ships constructed of Grade A, Grade E and Grade EH steels on the basis of mechanical properties and corrosion resistance. A spectrum of corrosion rates was observed but several electrodes were found to be compatible with all baseplates ...

A shielded metal arc welding expert system
Computers in Industry, 1993Abstract Shielded metal arc welding (SMAW) has been the welding industry's mainstay and heavily used in construction. SMAW is governed by a large variety of factors, and so it is very difficult to gain expertise in SMAW procedures. This paper presents an expert system to help plan and train shielded metal arc welding (SMAW) operations.

The importance of spatter formed in shielded metal arc welding
Materials Characterization, 2007Spatter results when droplets of liquid metal that have been ejected from the weld pool by the impact of small droplets from the covered electrode solidify and weld to the surface of the base material. The present paper studies spatter and reveals why these small droplets do not oxidise during their short trajectory and accounts for why they arrive ...

EVALUATION AND MONITORING OF UVR IN SHIELD METAL ARC WELDING PROCESSING
Health Physics, 2007This study established a comprehensive approach to monitoring UVR magnitude from Shield Metal Arc Welding (SMAW) processing and quantified the effective exposure based on measured data. The irradiances from welding UVR were calculated with biological effective parameter (Slambda) for human exposure assessment.

Effect of current and chemical composition on the hardness of weld in shielded metal arc welding
Materials Today: Proceedings, 2020Abstract Shielded metal arc welding is the most general purpose and popular welding process. Current of welding is the main controlling factor for the properties of welded product. Hardness of the product is generally required property while in work which depends upon the chemical composition of the product. The main purpose of this research work was

To study the influence of process parameters on weld bead geometry in shielded metal arc welding
Materials Today: Proceedings, 2021Abstract Mechanical properties of welded joints are greatly affected by weld bead geometry. Reinforcement height, depth of penetration and weld bead width are considered to be extremely important factors of weld bead geometry. In this research work, the influence of input process parameters like welding current, welding voltage, welding speed and ...

Metal gas reactions in gas-shielded arc welding
Welding International, 1988Abstract Mixed gas-shielded arc welding is becoming more and more popular. The influences of the gas components on arc and material transfer are known to a considerable extent. There is as yet no general quantitative description of the chemical behaviour of the gases dependent on the composition of the gas shield in arc welding.
