Three-Dimensional Modeling of Gas Metal Arc Welding of Aluminum Alloys

A three-dimensional mathematical model and numerical techniques were developed for simulating a moving gas metal arc welding process. The model is used to calculate the transient distributions of temperature and velocity in the weld pool and the dynamic shape of the weld pool for aluminum alloy 6005-T4. Corresponding experiments were conducted and in good agreement with modeling predictions. Th...

Solidification Behavior of Al-Mg Aluminum Alloy Using Double-Sided Arc Welding Process

As popular aluminum alloys, the 5xxx Al-Mg series, such as 5050 and 5052, etc., are widely used in applications such as automobile, pressure vessels, armor plate, and components for marine and cryogenic service. In this, as in all non-heat-treatable aluminum alloys, the weld metal zone is considered to be the weakest part of the joint and is the location of failure when the joint is loaded in t...

Submerged Arc Surfacing with a Multiple-wire Electrode

Surfacing is a technological procedure of applying a layer of filler material to a surface of another material, i.e. a product. By surfacing, it is possible to improve chemical, mechanical, and physical properties of the parent metal, and, consequently, those of the product surfaced. Surfacing may be applied to worn surfaces as well as to new products. A surfacing weld may have the same, simila...

Welding Aluminum Alloy 6061 with Opposing Dual Torch Gtaw Process

Cracking is a major concern in welding aluminum alloys. Although weld solidification cracks can be eliminated through addition of filler alloy, the additives modify the alloy or base-metal constituents and may not always be desirable. High-energy beam processes, such as electron-beam welding, that result in minimal heat input reduce crack sensitivity, but their high cost limits their applicatio...
