چکیده
Welding fumes have been found to be carcinogenic and stainless steel welders may at higher risk due increased formation of hexavalent chromium (Cr(VI)). The slag-shielded methods, identified generate most airborne particles Cr(VI), would potentially harmful. With ever-stricter limits set protect workers, measures minimize human exposure become crucial. Austenitic flux-cored wires 316L type developed with the aim reduce toxicity welding fume without compromised usability. Collected were compared formed using solid, metal-cored, standard wires. In part 1, new concluded improved weldability, even less Cr(VI) in wt.-% than solid wire acute toxic cultured bronchial epithelial cells as 2, two additional institutes created emission datasheets for same correlation data obtained 1. reported values showed large variations between three laboratories, having a significant effect on deviation. This is suggested result different parameters various ways collect analyze fume. More stringent specifications parameter settings collection required increase accuracy. means that present, it not possible compare from producers care should taken interpretation given available literature. Nevertheless, laboratories confirmed trends presented

An Evaluation of Welding Processes to Reduce Hexavalent Chromium Exposures and Reduce Costs by Using Better Welding Techniques
A group of stainless steel arc welding processes was compared for emission rates of fume and hexavalent chromium, and costs per meter length of weld. The objective was to identify those with minimal emissions and also compare relative labor and consumables costs. The selection included flux-cored arc welding (FCAW), shielded-metal arc welding (SMAW), and multiple gas metal arc welding (GMAW) pr...
متن کاملProfiling mild steel welding processes to reduce fume emissions and costs in the workplace.
To provide quantitative information to choose the best welding processes for minimizing workplace emissions, nine gas metal arc welding (GMAW) processes for mild steel were assessed for fume generation rates, normalized fume generation rates (milligram fume per gram of electrode consumed), and normalized generation rates for elemental manganese, nickel, and iron. Shielded metal arc welding (SMA...

J. Matusiak, J. Wyciślik, Institute of Welding, Gliwice, Poland The article presents the results of research into the fume and gas emission during MIG/MAG arc weld brazing. Investigations were conducted for hot dip coated steel sheets with zinc and zinc and iron alloy coatings. Steel grades of DX 54D Z 100 MBO and DX 54D ZF 100 RBO were used during research. ARC shielding gases applied were Ar ...
متن کاملCorrosion and Tissue Reaction to MP35N, L605 & 316L Guide Wires in Combination with a Conventional 316L Cannulated Stainless Steel Screw
INTRODUCTION: Cannulated screws, along with guide wires, are commonly used for a variety of orthopedic indications. Typically they are used for fractures in cancellous regions. Breakage or bending deformation of the guide wire is a clinical concern. Therefore it would be advantageous to use Co-Cr alloys such as MP35N and L605 in these applications as the occurrence of breakages and bendings wou...
