introduction acute poisoning by oral ingestion of mixed hazardous materials can lead to multiorgan toxicity and may represent a special challenge in clinical management, in particular if little is known about the effects of the involved agents. this is especially true when industrial chemical substances have been swallowed, as a huge variety of toxic substances must be taken into account. concl...

V. Marušić, I. Samardžić, I. Opačak. Faculty of Mechanical Engineering in Slavonski Brod University of Osijek, Croatia. The research investigated properties of aluminum bronze welded to structural steel St 52-3 N. Surface material CuAl-A3 was welded in one and two layers. There were dimension, metallographic examination of structures and hardness measured before and after heat treatment and aft...

Currently there is a huge competition amongst the OEMs and manufacturers in the auto industry to reduce the weight of the car. A few design modifications or use of different size and grades of materials solves this problem greatly. This paper focuses upon the metal finishing process of Laser Welded Blanks (LWB) with simulation and reliability as well as new process development. These blanks are...

Welding involves a metallurgical union process that relies on base metal fusion, i.e. the constituent metal of the structure, with or without filler metal, to form the soldered joint. Thus, a definition of welding proposed by the AWS is an "operation which aims to get localized coalescence produced by heating to a suitable temperature, with or without applying pressure and filler metal, produci...

The problems of distortion, residual stresses and reduced strength of structure in and around a welded joint are of major concern in the shipbuilding industry and in other similar manufacturing industries. The present paper deals with the theoretical analysis of transverse shrinkage in a welded butt joint. The mathematical model used in this analysis is based on the assumption that the plate un...

This paper deals with an experimental investigation on the friction stir welding of pure copper. 4 mm thick copper plates have been welded in the butt joint configuration using a conical unthreaded tool, with and without preheating. An electrically heated backing plate has been employed to increase the initial temperature of the plates and to investigate the influence of pre-heating on the weld...
