Can Your Welding Machine TIG Weld Aluminum?

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

Arc Welding Aluminum: How to Stick Weld Aluminum

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

Tig Welding Aluminum

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

Welding Aluminum

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

Welding Stainless Steel vs Aluminum

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 Aluminum With Square Wave Alternating Current

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

TIG Welding Aluminum With Alternating Current

TIG welding aluminum with alternating current has an advantage of self cleaning action while using alternating current. However, while using AC – using the right technique for welding is necessary. Characteristics Of TIG Welding Aluminum With Alternating Current (AC) Process Welding aluminum by the gas tungsten arc welding process using alternating current produces an oxide … Read more

Stud Welding Aluminum

Stud welding Aluminum may be accomplished with conventional arc stud welding equipment, using either the capacitor discharge or drawn arc capacitor-discharge techniques. The conventional arc stud welding process may be used to weld aluminum studs 3/16 to 3/4 in. (4.7 to 19.0 mm) diameter. The aluminum stud welding gun is modified slightly by the addition of … Read more
