Joining aluminum sheet in the automotive industry—A 30 year history. Welding Journal (Welding Research). 2012; 91What is Spot Welding? (A Complete Welding Process Guide)Spot welding (also known as resistance spot welding) is a resistance welding process. This welding process is used primarily for welding two or more metal sheets together by applying pressure and heat from an electric current to the weld area. It works by contacting alloy electrodes to the sheet surfaces, whereby pressure and electric

Jul 25, 2018· However, little research has been conducted on using micro resistance spot welding (mRSW) to join SS and Al by inserting a (Zn) sheet between them as an interlayer. The automotive industry uses a process to weld dissimilar metals, such as aluminum alloy (AA) and (SS), to reduce vehicle weights and thereby improve fuelSpecification for Automotive Weld Quality—ResistanceMar 09, 2017· This document contains both visual and measurable acceptance criteria for resistance spot welds in aluminum. The information contained herein may be used as an aid by designers, resistance welding equipment manufacturers, welded product producers, and others involved in the automotive industry and resistance spot welding of aluminum.Welding: Controlling the risks from welding - HSEGood general ventilation is usually sufficient to remove welding fume from low intensity resistance spot welding processes where the welding is on clean uncoated metal. Eye protection is required to safeguard against splatter. COSHH Essentials sheet WL3 gives more advice on fume control. Prevention of arc-eye using welding curtainsResistance Spot Welding in the Automotive IndustryTypical body structure assembly plants are based upon resistance spot welding technology as it is flexible, low-cost, fast, and can be applied to both aluminum-aluminum and - joints.
