Photobiological hazards in shielded metal arc welding

Physica Medica, 2023
Photobiological 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 ...

A shielded metal arc welding expert system

Computers in Industry, 1993
Abstract 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.

Shielded Metal Arc Welding

1993
Abstract Shielded metal arc welding (SMAW), commonly called stick or covered electrode welding, is a manual welding process whereby an arc is generated between a flux-covered consumable electrode and a workpiece. This article discusses the advantages and limitations and applications of the SMAW process and describes the equipment used ...

EVALUATION AND MONITORING OF UVR IN SHIELD METAL ARC WELDING PROCESSING

Health Physics, 2007
This 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.

L51416 Hyperbaric Shielded Metal Arc Welding - Cold Cracking

1982
Cranfield Institute of TechnologyResults incorporated in this report show that SMAW may be successfully applied to underwater repair and maintenance tasks. However, process tolerance is tight in view of limitations on acceptable pre-heat levels usable in confined sub-sea habitats.

Metal gas reactions in gas-shielded arc welding

Welding International, 1988
Abstract 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.

L51401 Hyperbaric Shielded Metal Arc Welding

1980
It is common knowledge that the welding arc is affected by the surrounding atmosphere (gas and pressure) and it was believed, prior to starting the present work, that metallurgical problems could also occur under hyperbaric conditions. These were mainly associated with the belief that some atmospheres could increase the heat extraction and consequently
