MAGNESIUM ALLOYS – Metallurgical Expertise

17.07.2020· Magnesium alloys are weldable using the GTAW, GMAW and even OFW processes with the help of Sodel 0681 flux. Some alloys weld better than others, but an acceptable weld can be made with the majority of these alloys. Classifiion. The magnesium alloy designation system was set up in 1948 by ASTM (American Society for Testing and Materials).

What Is Pot Metal, and How Do You Weld It?

Any serious welder comes across pot metal at some point in their welding assignments. But not every welder knows what pot metal is or how to weld it. Failure to have the facts can seriously compromise the quality of the welding that you do. You might easily, but wrongfully, weld this metal the same way you weld traditional metal.
