Welding Process Alloy. After the welding the material is kept at elevated temperature to keep it dry before Post Weld Heat Treatment PWHT. The GTAW gas-metal arc welding process has been used to weld thicknesses from 025 to 150 mm and can be used in all welding positions.
A WPS is supported by a Procedure Qualification Record PQR or WPQR. Past experience may show preferential corrosion in the weld in which case moving up in. After the welding the material is kept at elevated temperature to keep it dry before Post Weld Heat Treatment PWHT.
Magnesium alloy components may be joined using mechanical clasps as well as a variation of welding methods including tungsten arc inert gas TIG plasma arc welding electron beam welding EBW laser beam welding LBW friction stir welding FSW explosion electromagnetic welding ultrasonic welding and resistance spot welding RSW.
However certain precautions must always be considered. After the welding the material is kept at elevated temperature to keep it dry before Post Weld Heat Treatment PWHT. Ad Find China Manufacturers Of Welding Wire. All the common arc processes are applicable in Welding-alloy-steel the selection being determined mostly by economic and practical considerations.
