A Comparative Evaluation of Welding Consumables for Dissimilar Welds between 310 Austenitic Stainless Steel and Inconel 657
The current work was carried out to characterize welding of AISI 310 austenitic stainless steel to Inconel 657 nickel-chromium superalloy. The welds were produced using four types of filler materials; the nickel-based corresponding to Inconel 82, Inconel A, Inconel 617 and austenitic stainless steels 310. Of the two joints involved, this paper describes the choice of welding consumables for the...

Metal arc welding ranges from primitive (manual) to increasingly complex automated welding processes. Welding occupies 1% of the labour force in some industrialised countries and increasing knowledge of health risks, necessitating improved assessment strategies and controls have been identified by the International Institute of Welding (IIW), ILO, WHO and other authoritative bodies. Challenges ...
متن کاملInstruments and consumables
Our recent issue on “Equipment for eye care” (number 73, September 2010) addressed the importance of equipment in the delivery of eye care and covered maintenance, repair, training, purchasing, and donations. This issue (number 76) addresses similar concerns around surgical instruments and consumables. For an eye unit to function, instruments must be carefully managed so that they remain in goo...
متن کاملEvaluation of the Pulmonary Toxicity of a Fume Generated from a Nickel-, Copper-Based Electrode to be Used as a Substitute in Stainless Steel Welding
Epidemiology has indicated a possible increase in lung cancer among stainless steel welders. Chromium (Cr) is a primary component of stainless steel welding fume. There is an initiative to develop alternative welding consumables [nickel (Ni)- and copper (Cu)-based alloys] that do not contain Cr. No study has been performed to evaluate the toxicity of fumes generated from Ni- and Cu-based consum...
