These joints created by resistance spot welding form a “button” or “fused nugget.” Resistance spot welds are found typically on flanges, staggered in a single row of consecutive welds. Vehicle manufacturers use resistance spot welding in the factory []
Email: Dave@titespotIn resistance spot welding, aluminum deterioration of the electrode tip is further accelerated by the inherent physical, mechanical properties and surface condition of the work pieces. It is a well known and accepted fact that the resistance spot welding weldability of aluminum in the as received mill finish condition is both poor and erratic.

Welding aluminum is not as hard as you think. Turns out you can weld aluminum without a welder! This instructable will teach you how to use a propane torch and some aluminum brazing rods as a quick way to bond aluminum without using a welder. It makes for a very strong bond and with a little practice can be done quickly with great looking results.
1. The blue Bernzomatic will work just fine but I prefer using the yellow premium touch as it's hotter and works much quicker.2. You'll also need some aluminum brazing rods. I purchased all of these things at Home Depot.3. What I like about using aluminum is it's soft enough to cut with ordinary woodworking saw blades.4. I'll then chamfer the edges to allow a channel for the brazing material.5. Before brazing it's very important that the aluminum is clean.6. Clamp up the tubing and start heating the aluminum with a propane torch. Aluminum will start to melt at 1200deg Fahrenheit but the brazing rod w...7. Rub the brazing rod along the channel until it's filled in and finish it off with some more heat. If you don't get the aluminum hot enough the b...How Spot Welding works: while two metal sheets are held together by two copper electrodes, a substantial ac current passes via the electrodes and melts the sheet-metal right into a "spot" as a result welding both pieces together. Here at Metal Werks, Inc., we've various spot welding functions. Our experienced team is skilled in welding numerous ...

Resistance welding is a process that quickly and efficiently joins two or more thin sheets of metal, and “spot” welding is the most frequently used type of resistance welding. Here, the welded joint is formed by pressing electrodes with pointed tips at welding locations to focus the proper current and heat to particular places on the metals ...
Apr 16, 2019 When joints are located out of position and difficult to reach, pulse welding can produce cleaner welds. The base metal can congeal to the weld puddle during the trough in current preventing it from dripping out of the joint. [12] [13] Thin Metals. Pulse welding on thin metals reduces the risk of burn through. [14] Cosmetic Work
Aug 01, 2013 Gas metal arc welding (GMAW) is an effective method for joining light-gauge metals such as carbon steel and austenitic stainless steel. Thin-gauge materials—24-ga. to 0.1875-in. carbon steel and 18-ga. to 0.1875-in. stainless steel—are used in applications such as HVAC, automotive, mobile machinery guards and cabs, and small parts, as well as stainless steel food service and

In spot welding, a positive and a negative electrode make contact with the work piece-usually the parts to be welded are pinched between the electrodes. After the pressure has been applied a pulse of electrical current is released which causes the metal to melt between the welding electrodes. The result is a weld spot – hence the term “spot ...

Friction Stir Welding is a relatively new technique for joining metal. In some cases on aluminum joining, FSW gives better results compared with the arc welding processes, including the quality of welds and produces less distortion. The purpose of this study is to analyze the effect of high speed tool rotation on micro Friction Stir Spot Welding (μFSSW) to the shear fracture load of the welds.
