Plasma arc welding

Plasma arc welding

The plasma arc welding procedure is usually compared to the gas tungsten arc process. If an electric arc between a tungsten electrode and the work is constricted in a cross-sectional area, its temperature increases because it carries the same amount of current. This constricted arc is called a plasma, or the fourth state of matter.
TIG welding A-Z

TIG welding A-Z

TIG welding , called another name of gas tungsten arc welding, is an arc welding process that operates at high temperature (over 6,000 degrees Fahrenheit) to melt and heat metals. While it is more expensive than stick welding, it is cleaner and more versatile (works on steel, aluminum, brass and many other metals).It results in high quality welds.
Basic arc welding technique

Basic arc welding technique

Arc welding is the process of joining two metal workpieces together using a flux covered electrode which is melted in an electric arc and becomes a fused part of the pieces being welded. Arc welding requires time, effort and patience to master as the weld rod position is very delicate to the position of the workpiece. The following is a simple guide to learn the basic technique of arc welding.

Difference between MIG welding and MAG welding

Difference between MIG welding and MAG welding


MIG/ MAG welding is a method of welding metal arcs in a protective gas environment, also known as welding wires, CO2 welding. Gas Metal ARC Welding (GMAW) is another name of MIG/MIG welding
Soldering - Types and techniques

Soldering - Types and techniques

Soldering is a welding method to connect solid metal or alloy parts by means of a metal or intermediate alloy called a solder. During the welding process, the metal (or intermediate alloy) is fired to the flow state, while the welding metal only needs to be heated to a certain temperature at which brazing metal and solder can diffuse into each other.
