TIG Welding Aluminum DC Electrode Negative

When TIG welding aluminum, direct current straight polarity (DCSP) is the most commonly used. This article seeks to discuss welding techniques, joint designs, and types of aluminum alloys that can be welded, when TIG welding aluminum with DCEN (or direct current electrode negative). Note that DCEN and DCSP are same. Characteristic Of TIG Welding Aluminum … Read more

TIG Welding Aluminum With Direct Current Straight Polarity (DCSP)

Characteristic Of TIG Welding Aluminum With Direct Current Straight Polarity In this process, using helium and thoriated tungsten electrodes is advantageous for many automatic welding operations, especially in the welding of heavy sections. Since there is less tendency to heat the electrode, smaller electrodes can be used for a given welding current. This will contribute … Read more

Sections Of A Weld

The following terms are used to describe the parts or sections of a weld: Fusion Zone (Filler Penetration) The fusion zone is the area of base metal melted as determined in the cross-section of a weld. Leg Of A Fillet Weld The leg of a fillet weld is the distance from the root of the joint … Read more

Miller Diversion 165: Ac/Dc TIG Welder

Miller TIG Welder Diversion 165 AC/DC TIG Welder has an Easy-to-understand operator interface. The machine has only three switches with which the welder needs to operate the machine: Power switch Material selection switch Amperage control/material selection switch The power source is inverter-based, that works with AC and DC equally well. It has little down time. The … Read more

Oxy acetylene Aluminum Welding

While aluminum has a melting point less than half that of steel, its conductivity is over three times as great, so we use a tip about the same size for this metal as we do for steel, and because of this conductivity, we should realize that the effects of expansion and contraction must be particularly guarded against, … Read more
