Tungsten Inert Gas welding (TIG) process is an important component in many industrial operations. The TIG welding parameters are the most important factors affecting the quality, productivity and cost of welding. This paper presents the influence of welding parameters like welding current, welding speed on strength of low carbon steel on AA1050 material during welding. A plan of experiments bas...

Martensitic stainless steel AISI 431 and low carbon 1020 are materials used together in many different industries. However, important problems encountered when welding (fusion welding) these to each other. For this reason, friction process (Solid-state is join dissimilar metals. There very few studies on joining with welding. Therefore, the optimization of parameters pairs great important. In a...

A novel approach for predicting the intermetallic compound (IMC) formation during friction stir welding (FSW) of AA6061 to commercially pure copper has been developed, in addition their effect on mechanical properties. The temperature distribution aluminium weld nugget determined by a finite element model, use an Al–Cu phase diagram and elemental concentration have combined predict validate sev...

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...

Resistance spot welding is a common process to join metals in the automotive industry. Adhesives are often used as sealers to seams of metals that are joined. Anti-spatter compounds sometimes are sprayed onto metals to be welded to improve the weldability. Spot welding produces complex aerosols composed of metal and volatile compounds (VOCs) which can cause lung disease in workers. Male Sprague...

Metals in particulate matter (PM) are considered a driving factor for many pathologies. Despite the hazards associated with particulate metals, personal exposures for at-risk workers are rarely assessed due to the cost and effort associated with monitoring. As a result, routine exposure assessments are performed for only a small fraction of the exposed workforce. The objective of this research ...

A literature review of studies and researches has been attempted in the field of dissimilar metal welding. Dissimilar metal welds have numerous industrial applications in area of thermal power generation, chemical, petrochemical, automobile, aerospace industries and nuclear plants etc. The purpose of this paper is to review: (a) Dissimilar metal welds, their Metallurgical and Mechanical aspects...

Dissimilar metals joining, especially Aluminum (Al) to copper (Cu), have gained importance in batteries for electric vehicles. Although friction stir spot welding (FSSW) has recently been used dissimilar materials, progress very slow toward understanding the effect of temperature on diffusion condition between two materials with same FCC crystal structure. The thermo-mechanical modeling define ...

An improved welding electrode for producing weld metal having low amount of hydrogen therein so that hydrogen assisted cracking in weld zone is minimised. This is especially beneficial for welding high strength steel having tensile strengths of about 70000 psi or above. The reduction of slag /metal reaction temperature during welding have been found to have additional advantage of reducing the ...
