Magnesium Alloy Suppliers Rod Metal Products Dissolvable Magnesium Alloy Bar
Introduction:
The weldability of most magnesium alloys is good when proper filler metal in employed. A filler metal with a lower melting point and a wider freezing range than the base metal will provide good weldability and minimize weld cracking. AZ61A or AZ92A filler metals may be used to weld base metals of similar composition and also ZK21A base metal.
AZ61A filler metal is generally preferred for welding wrought base metals of those alloys because of lower cracking tendency. However, welds made in cast Mg-Al-Zn and AM100A base metals with AZ92A filler metal show less crack sensitivity. The weld metal will respond to the precipitation heat treatments normally applied to repaired castings. AZ101A filler metal may also be used to weld those cast base metals. EZ33A filler metal is used to weld wrought and cast base metals designed for elevated-temperature service; however, this filler metal should not be used for welding aluminum-bearing magnesium alloys because of severe weld cracking problems. When no other filler metal is available, most base metals may be welded with strips cut from the base metal.

Production-Quality Control
Quality Control in our foundry begins on the foundry floor, where the first line of inspection is the casting and molding crew, our lab technicians inspectors and managers completes the quality team. Our quality control staff carefully monitors raw material, core materials,packaging and all aspects of production.
