Iranian Scientists Reach Technology to Join Dissimilar Alloys
Reducing production costs and increasing productivity in various industries are among the advantages of using these high-tech parts.
“In this method, dissimilar metal parts are joined at a temperature of 1150 degrees through induction welding, a method that increases the strength of the joints by 20 to 30 percent,” said Faraj Tati Khani Verdi, the designer of the dissimilar metal joining device.
He explained that dissimilar bimetallic materials like nickel-based superalloys or a high-entropy alloy can be joined with a device made with a special filler made of a high-entropy alloy, adding that parts made with mechanical alloying technology increase the strength and life of the parts and increase efficiency.
“The foreign model of this tool is capable of machining 8,000 parts, but with this manufacturing method, it can machine over 24,000 parts. In other words, the life of the part has tripled,” Tati Khani Verdi said.
Joining dissimilar metals is a critical aspect of many engineering and manufacturing applications. Whether in the automotive, aerospace, or HVAC industries, creating reliable joints between different metals, such as steel and copper or aluminium and stainless steel, requires careful consideration and the right materials. Understanding how to join dissimilar metals is essential for ensuring structural integrity, minimising corrosion, and achieving optimal performance.
Dissimilar materials provide industry with combinations that can fulfil specific service requirements for a range of applications. These include offering increased performance and functionalities, as well as desirable characteristics, such as combinations of high strength and light weight, or preferential galvanic corrosion in the presence of an electrolyte.
