چکیده
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 + O2, Ar + CO2, Ar + H2 and Ar + CO2 + H2 gas mixtures. Analysis of the results covers the influence of chemical composition of shielding gas effect on the emission rate of total fume, nitrogen oxides and carbon monoxide.

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 کاملInfluence of shielding gas composition on weld profile in pulsed Nd:YAG laser welding of low carbon steel
Weld area and weld depth/width ratio can be considered to be of the most important geometrical factors in pulsed laser welding. The effects of carbon dioxide and oxygen additions to the argon shielding gas on the weld properties in pulsed laser welding of low carbon steel is investigated. Presence of carbon dioxide and oxygen up to 10 and 15 percent respectively decreases the weld geometrical f...

متن کاملInfluence of shielding gas composition on weld structure in pulsed Nd: YAG laser welding
This work studied the effect of additions of carbon dioxide to argon shielding gas on the weld shape and microstructure of ST14 steel in pulsed Nd: YAG laser welding. By additions of carbon dioxide up to 15%,the weld area and depth/width ratio decreases while rising of carbon dioxide up to 25% causes increasing of weld area and depth/width ratio. It is observed that the weld metal microstructur...
