Study on Mechanism of Welding Hot Crack for Magnesium Alloys
The TIG welding was used to weld AZ31B magnesium alloys. The results indie that hot cracking is related to the chemical composition of the filler metal and the welding current. When the AZ40M alloy, with low content of Zn, is used for the filler metal, no hot cracking appears in the weld. While the AZ31B alloy is used as the filler metal, or with no filler metal, hot crack appears in the

Welding Alloys for sale online | Mister Worker™
The copper-based alloys in the Stella Welding Alloys alogue are used for welding with TIG or MIG techniques. MIG welding ( Metal-arc Inert Gas ) is a continuous wire process in which the weld pool is protected by the emission of an inert gas, which flows from the torch directly on the material.
Aluminium alloys in marine appliions
T HE WROUGHT aluminium alloys (rolled and extruded) that are used in marine appliions belong for the most part to two series: the 5000 series comprising alu-minium-magnesium alloys, and the 6000 series which consists of aluminium-magnesium-silicon alloys. In view of their specific aptitudes for being `worked'', most rolled
Double-Sided Arc Welding of AZ31B Magnesium Alloy Sheet
welds must be found in order to facilitate the use of sheet magnesium alloys in the form of tailor-welded blanks for structural appliions. However, existing welding processes, such as RSW, GTAW, GMAW, laser and hybrid laser-arc each have disadvantages when applied to the welding of magnesium alloy sheet in the butt-joint configuration.
