What is multi spot welding?
Multi spot welding machine is a composite technology machine to achieve higher production. One of the methods employ common transformer and welding in sequence one after another spot welding. Initiating the cycle makes pair of electrode come down and weld two joints at a time. In sequence all the joints are welded.
What are the types of spot welding?
The types are: 1. ‘Pedestal Type’ Machine 2. Resistance Butt or Upset Welding 3. Flash-Butt Weld 4.
What is RSW in welding?
A resistance welding process that produces a spot weld at the faying surfaces of overlapped parts.
What is the maximum thickness for spot welding?
3 mm
Spot welding is primarily used for joining parts that are normally up to 3 mm in thickness. Thickness of the parts to be welded should be equal or the ratio of thickness should be less than 3:1. The strength of the joint depends on the number and size of the welds. Spot-weld diameters range from 3 mm to 12.5 mm.
What is the difference between seam welding and spot welding?
A seam weld is a continuous weld along a joint. Unlike a spot weld that uses a single point electrode, a seam weld uses a rotating wheel electrode that produces a rolling resistance weld. This process is most often used to join two sheets of metal. MIG and TIG welders can be used to do seam welding.
How are spot welding parameters calculated?
One general criterion of resistance spot-welding is that the weld shall have a nugget diameter of 5*t1/2, “t” being the thickness of the steel sheet. Thus, a spot weld made in two sheets, each 1 mm in thickness, would generate a nugget 5 mm in diameter according to the 5*t½-rule.
Which electrode is used in spot welding?
Electrode materials typically used for spot welding copper include molybdenum and tungsten.
What is the correct sequence for spot welding?
Spot welding involves three stages; the first of which involves the electrodes being brought to the surface of the metal and applying a slight amount of pressure. The current from the electrodes is then applied briefly after which the current is removed but the electrodes remain in place for the material to cool.

What are the dangers of Sparks in welding?
SPOT WELDING can cause fire or explosion. Sparks can fly off from the welding arc. The flyingsparks, hot workpiece, and hot equipment cancause fires and burns. Accidental contact of elec-trode to metal objects can cause sparks, explosion,overheating, or fire. Check and be sure the area is safe before doingany welding.
