Spot Welding Aluminum Sheet Metal

For commercial quality welds on 1 2mm mill finished sheets weld settings are typically in the region of.

Spot welding aluminum sheet metal.

In this video lazze shows how you can spot weld aluminum with a standard 220 volt spot welder that is probably already in your shop. A 5356 filler metal also works for 5052 materials specifically. For designers welding also offers a lot of freedom because you don t have to design flanges to accommodate a rivet or spot weld and geometry can be more dynamic. Share this trick and if.

Welding aluminum requires a thorough understanding of the tig welding process and also requires a tig torch. The high quality finish and verstaile nature make it a common choice for welding aluminum and other metals. Aluminum spot welding is becoming more common as aluminum replaces steel in many applications where weight is main such as automobiles. The standard bs en iso 18595 resistance welding spot welding of aluminium and aluminium alloys weldability welding and testing provides useful guidelines.

When welding sheet metal the main thing to look out is to prevent warping and burn through. It s also easy to do with a spot welding machine which has 2 electrode tongs about 6 inches 15 cm long that pass an electrical current through the metal to fuse them together. To prevent burn through and warping don t whip or weave the torch. It requires a lot of experience patience and skill to get the desired results.

Even professional welders can create excessive heat affected zones and burn through while welding sheet metal. This type of electrical power is wanted for the big output current that spot welding requires. The more time the arc is in an area the hotter it. Techniques for welding sheet metal.

We all know that welding is cool to watch with special shields or goggles on of course and welds have a nice surface finish once they are ground and polished. Spot welding uses the heat from an electrical current to join 2 pieces of metal quickly and is typically used for joining sheet metal. Typical aluminum alloys for sheet fabrication are 3003 and 5052. Tig welding is an advanced technique that involves the use of both hands in a slow and controlled manner.
