What is dcrp in welding?
dcrp = direct current reverse polarity
What is polarity in welding?
Polarity in welding has to do with the direction of the current in the welding process. With direct current (DC) the welding circuit can either be straight, or reverse polarity. When the machine is set for straight polarity, the current flows from the electrode to the weld surface and creates considerable heat in the metal. When the machine is in reverse polarity, the current is backwards and is flowing from the metal to the electrode causing a grater concentration of heat at the electrode.
What is the difference between the welding current produced by alternator and the one produced by a generators?
Alternators produce Direct Current, Generators produce Alternating Current. Todays' cars have Alternators to charge the batteries.
What is cs welding?
CS Welding is known as Carbon Steel welding that is more beneficial and easy to use for welding purpose.
Can a DC motor be turned into a welder?
A dc is an acronym for direct current & 2 be put in to use,changed to ac which could then be used in welding
What do the following abbreviations mean ac dcen dcep dcsp dcrp?
These abbreviations as related to welding: AC is alternating current (current that cycles between positive and negative peaks 120 times a second in the USA on a 60 HZ cycle) DCEN is direct current electrode negative DCRP is direct current reverse polarity and is the same as DCEN DCEP is direct current electrode positive DCSP is direct current straight polarity and is the same as DCEP
What do the following abbreviations mean ac dcen dcep dcsp and dcrp?
These abbreviations as related to welding: AC is alternating current (current that cycles between positive and negative peaks 120 times a second in the USA on a 60 HZ cycle) DCEN is direct current electrode negative DCRP is direct current reverse polarity and is the same as DCEN DCEP is direct current electrode positive DCSP is direct current straight polarity and is the same as DCEP
What is the purpose of a magnetic field produced by charges in a current?
Depends whether Direct Current or Alternating Current. Only Alternating Current produces magnetic field.
Explain welder polarity?
Welder polarity has to do with DC (Direct Current) welders. Essentially, polarity is the direction of the current. Straight polarity means that the current is running from the electrode, to the metal, and back through the grounding clamp. Reverse polarity means that the current is going the opposite way, from the grounding clamp, through the metal, and up through the electrode.
What determines weather the polarity of a welding machine is set for dcen or dcep?
DCEP supplies about two-thirds of the heat at the end of the rod, which allows more digging action, or penetration, into the base metal. It's what you want to use for thick steel. For thin steel, direct current electrode negative (DCEN) is best.
What is the term tw refers to in welding?
TW = thermite welding, a welding process that requires no external source of heat or current.
Where you get welding objective type question and answer?
welding current for 2mm thick. ms plate
