In SMAW Welding Process DCEP and DCRP are same?
yes Electrode Positive is the same as Reverse Polarity
Why do you change polarity DCRP-DCSP in SMAW?
Using DCSP when welding thin material causes more heat to be concentrated in the electrode than in the base metal. This prevents the arc from burning thru thin materials before the electrode melts.
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 is reverse polarity in welding?
This is applicable to DC supply Arc Welding.In Layman language, when the electrode is given positive potential and the work piece is given negative potential, the weld formed is shallow and wide, this method is called 'Direct Current Reverse Polarity' (DCRP) welding procedure.When the machine is set on straight polarity, the electrons flow from the electrode to the plate, concentrating most of the heat on the work. With reverse polarity, the flow of electrons is from the plate to the electrode, thus causing a greater concentration of heat at the electrode. Because of this intense heat, the electrode tends to melt off; therefore, direct current reverse polarity (DCRP) requires a larger diameter electrode than direct current straight polarity (DCSP). Notice that DCSP produces a narrow, deep weld. Since the heat is concentrated on the work, the welding process is more rapid and there is less distortion of the base metal. Overall, straight polarity is preferred over reverse polarity because you can achieve better welds. DCRP forms a wide and shallow weld and is rarely used in the GTAW process. The exception to this is when it is used to weld sections of aluminum or magnesium.DCRP has excellent cleaning power that results from the action of positive charged gas ions. When these gas ions strike the metal, they pierce the oxide film and form a path for the welding current to follow. This same cleaning action occurs in the reverse polarity half of an alternating current welding cycle.
What is the welding cert roster code for welding?
roster welding
Name of the type of welding?
One type of welding is tube welding. Another type if mig welding.
Difference between ERW and SAW welding?
SAW welding is a type of arc welding while ERW welding is spot or seam welding. SAW stand for submerged arc welding while ERW stands for electric resistance welding.
What are smaw welding?
smaw welding is sheilded metal arc welding
What is the difference between ultrasonic welding and radio frequency welding?
what is the difference between ultrasonic welding & radiographic welding
What type of welding machine use in spot welding or resistance welding?
Mainly In spot welding & resistance welding two type welding machines are used :- 1. Air Cooled & 2. water Cooled.
What is cs welding?
CS Welding is known as Carbon Steel welding that is more beneficial and easy to use for welding purpose.
