ARC WELDING | PRINCIPLE OF ARC WELDING | POLARITY IN WELDING | DCSP | DCRP | DCEN | DCEP

Hello Friends
In this Lecture, we are going to understand the Arc Welding in details with appropriate diagram . If you have any doubt you may ask in comment section, I will try to reach you with your answers soon. We will study the following topic in this video:
*Arc Welding or Electric arc Welding.
*Working principle of Arc welding.
*Different between Arc and spark.
*What is Polarity meaning in Welding.
*Straight Polarity.
*Reverse Polarity.
*Depth of penetration in various polarity.
*Depth of penetration in Straight polarity.
*Depth of penetration in AC.
*Application of Arc welding.

[@philuong9729]

Why the depth of penetration you showed is difference from SCWIP 3.1:
- DCEP: When the electrode is on the positive pole of the welding circuit, the workpiece
becomes the negative pole. Electron flow direction is from the workpiece to the
electrode. When the electrode is positively charged (DC+ve) and the workpiece is
negatively charged the two thirds of the available heat energy is at the tip
of the electrode, with the remaining one third being generated in the parent
material, resulting in an increase in weld penetration.
- DCEN: When the electrode is on the negative pole of the welding circuit, the workpiece
becomes the positive pole, electron flow direction is from the electrode to the
workpiece. The distribution of energy is now reversed. One third of the available
heat energy is generated at the tip of the electrode, the remaining two thirds in
the parent material.
Direct current with a negatively charged electrode (DC-ve) causes heat to
build up on the electrode, increasing the base metal melting rate and
decreasing the depth of the weld penetration depth.

[@mechanicalnexus]

In DCEP- weld deposition is high and in DCEN - high heat on workpiece introduced high penetration rate. Your words are right... I appreciate it. 👍

Globular transfer means the weld metal transfers across the arc in large droplets (i.e. more than dia of electrode), and mainly uswd for carbon steel, and here CO2 used as shielding gas
