Aluminum can be joined by welding, brazing, as well as soldering. The choice of process depends on the strength of the joint required, composition of the base metal, joint configuration. Each process offers its’ own set of advantages and limitations. In this article, we shall discuss a few aspects related to the gas welding of … Read more
Gas metal arc welding is a versatile process that is used widely to weld aluminum. Direct current electrode positive polarity is used, and an inert gas is used to provide shielding. The process can be adapted for out of position welding as well. Shielding Gas Aluminum is a reactive metal. Hence an efficient shielding is … Read more
A considerable number of people ask about welding machine requirements in order to TIG weld aluminum with direct current. TIG weld Aluminum with Direct Current Electrode Positive (DCEP) or DC(+) Can you TIG weld aluminum without AC and a High-Frequency box? Yes, you can actually weld aluminum with a low-cost DC power supply. It doesn’t make it any … Read more
When aluminum is welded with shielded metal-arc welding (SMAW) process, the stick electrodes are heavy coated. The flux does the function of chemically reacting with the aluminium oxide layer, and removing it. Besides this, the flux also performs the function of shielding the arc from atmospheric gases, and forms a slag over the completed weld. The … Read more
Gas tungsten arc welding, or TIG (Tungsten Inert Gas) arc welding process is a commonly used process for welding of low thicknesses of aluminum and aluminum alloys. This article discusses TIG welding of aluminum with three methods – with alternating current, with direct current straight polarity, and with square wave alternating current. Welding With Alternating Current … Read more
Aluminum is a very sought after material due to its many desirable properties. Some of these properties are: lightweight, excellent strength to weight ratio, easy machinability, formability, and weldability. Although pure aluminium has limited usability, it has vast usage when it is alloyed with few alloys. Fabrication using aluminium involves welding. And welding aluminum requires … Read more
The question of Stainless steel vs Aluminum often arises when considering components for a number of applications. Welding stainless steel is comparatively easier, however quality welds can be obtained with aluminum too if one understands its’ behavior. Fatigue Strength and Life Stainless steel has 5-10 times the fatigue strength (resistance to bending & vibration) of aluminum pipe. … Read more
TIG welding (or GTAW welding) of aluminum with square wave alternating current differs from conventional balanced wave TIG welding in the type of waveform used. With a square wave, the time of current flow in either direction is adjustable from 20 to 1. In square wave gas tungsten arc welding, there are the advantages of … Read more
