What is DC Welding? Direct current is an electric current that has a constant polarity flow in a single direction. This current can be positive or negative. With DC welding, since the magnetic field and current of the arc are constant, stable arcs are produced. Advantages The advantages of ...

Welding is a fabrication process that joins two or more materials using heat, pressure, or both to form a strong, permanent bond.
I. What is Polarity in Welding? 1) Types of Polarity Direct Current (DC):DC welding machines offer two types of polarity – direct current electrode negative (DCEN) and direct current electrode positive (DCEP). Alternating Current (AC):AC welding involves a constant change in polarity, altern...
The Fronius “What is …?” series helps to build an understanding of welding and to maintain an overview of the basic terms. Tungsten Inert Gas Welding TIG welding is a process that enables top-quality weld seams. The arc burns between a temperature-resistant, non-melting tungsten electrode,...
Switching DC-DC converters consist of a power switch, conductor coil, diode, and a storage capacitor. The number of these components and their arrangement can differ, affecting the converter’s work. The input voltage is applied in pulses, but the capacitor smoothes it. Their efficiency is much...
Every soldier is a leader or is out. Absurd. In the early 1970’s, I was present when our engineer battalion commander had a conversation with the Division Chief of Staff. He was complaining about the new up or out policy. He said; “I’ve got an E5, specialist five, road grader ...
Technical cleanliness is an analytical standard to determine the level of particulate contamination on machined parts. The goal of technical cleanliness is to characterize the particles on the components and to ensure that particles below a certain defin
In 3-phase power, at any given moment one of the three phases is nearing a peak. High-power 3-phase motors (used in industrial applications) and things like 3-phase welding equipment therefore have even power output. Four phases would not significantly improve things but would add a fourth...
