What else can I help you with?
In SMAW Welding Process DCEP and DCRP are same?
yes Electrode Positive is the same as Reverse Polarity
What are smaw welding?
smaw welding is sheilded metal arc welding
How do you reverse polarity on ac motor?
Reversing polarity is not possible with an ac motor. Some do have wiring that will allow you to change rotation. The type and model of the motor can tell you if it is reversible.
What SMAW rod is known as the code rod?
1040.
If we change the polarity of capacitor in ceiling fan why it starts rotating reverse direction?
by changing the polarity of capacitor of single phase ceiling fan can we change the direction of rotation from anticlockwise to clockwise
In SMAW Welding Process DCEP and DCRP are same?
yes Electrode Positive is the same as Reverse Polarity
Will changing the polarity of the current change the polarity of the electo magnet?
Yes!
What are the effects of the electrode polarity on welding in the SAW process?
Think of Polarity as water flow in a pipe. Reverse Polarity means the flow is from the work to the machine. Straight Polarity is flow from the machine to the work. Heat is released when the flow tries to jump the gap. So in Reverse Polarity (where most SMAW is done) the heat builds up in the base metal which is usually thicker than the Electrode. The extra heat there helps melt the base metal. Straight polarity is usually employed when welding thin metals.

Can the earth pole shift change battery polarity?
no it cannot
How do molecules generate friction or heat?
How is heat created in a chemical reaction? you say; It is created from bonds cracking.Each bond has large energy,when it cracks, releases its energy. We know that when friction accurse there is a release of electrons. We also know that the release will cause a polarity change or change in polarity intensity. Is this change, not the same as the change taking place in the chemical reaction? Is it not polarity that bounds atoms? I THINK..... the answer is the same in both cases. change in polarity, intensity or the release of electrons. MY name is JACK D PRESNULL.

The polarity of an electromagnet is determined by what?
The polarity of an electromagnet is determined by the direction of the electric current flowing through the wire coil. Reversing the direction of the current will change the polarity of the electromagnet.
What is the minimum thickness of metal normally welded using the smaw process?
The minimum thickness for SMAW welding is about 18 ga. with a steady hand.
Why ac current attract?
As we touch an ac supply in which due to body resistance , we create a phase difference between the ac supply and us . As ac reverses polarity , so do we , but our polarity change is opposite to that of the polarity change of ac supply , hence our body gets attracted to the ac supply .
What are the advantages of SMAW?
Advantage of smaw :*equipment is relatively inexpensive Equipment is portable because the welding machine can be powered with gasoline or diesel powered w/ engines.
What is the difference in welding rods for ac welders and dc welders?
The difference in the ac/ dc , or polarity of welding rods is in the makeup of the flux coating , or the alloy of the metal, and in the case of SMAW ( Shielded metal arc welding ) rods , which have a flux coating, are usually marked on the base of the rod.
How do you calculate nomber of electrode in SMAW welding?
no need
