2018-11-30 · Welding of aluminum and its alloys poses several problems to the designer as they are prone to hot cracking and porosity. To overcome this, a relatively new automated TIG welding with continuous wire feed arrangement is employed for joining two dissimilar aluminum alloy with pulse TIG welding. Trial runs were conducted on dissimilar aluminum

Resurfacing Welding

The cold welding surfacing equipment does not deform or anneal metal workpieces after repairing, and has high welding strength and wear resistance. It can pass the metallographic, tensile and hardness tests, and the metallurgical coination of the welding material and the substrate guarantees the firmness of the welding.

Research on Friction Stir Spot Welding Brazing …

Friction stir welding (FSW) is the most popular and efficient method for solid-state joining of similar or dissimilar metals and alloys. This technology is mostly applied in aerospace, rail, automotive, and marine industries. In order to reduce the weight of special auto parts, friction stir spot welding (FSSW) was proposed by some researchers for the connection of steel-aluminium dissimilar

PREVENTION OF POROSITY IN ALUMINUM WELDS – …

2018-4-3 · Porosity is one of the main defects or discontinuities that may be encountered when welding aluminum and its alloys. The phenomenon is caused by the hydrogen gas that cannot escape from the molten metal, while still remaining entrapped in the microstructure after cooling. In fact, the hydrogen is very soluble in liquid pure aluminum with…

2  · Keywords: Hot wire TIG, automatic GTAW welding, narrow gap torch, welding automation, cladding, flow sensors, nuclear components. 1. Abstract The hot wire GTAW (TIG) process is an under-utilized technology that can pay big dividends in the right appliion and when used in industries requiring high quality, high productivity welding.

Aluminum Welding: The Cost and Cure of Porosity

Molten aluminum has a high solubility for hydrogen; solid aluminum doesn’t, so the hydrogen tries to escape before cooling. If the weld pool cools too quickly, the hydrogen remains in the weld metal, causing porosity. This often calls for a slower cooling rate from higher welding currents, slower speeds, preheating, or a change in weld design.

Filler Wire For Welding Aluminum Alloys - Cottignies, …

2008-8-14 · An aluminum-based welding filler wire is made with an aluminum alloy that contains between 0.1 and 6 wt. % titanium, including one portion in the form of TiB 2 particles, TiC particles, or a coination thereof, and another portion in the form of free titanium. The filler wire can be used in welding aluminum-based materials.
