Visualisation of alternating shielding gas flow in GTAW [PDF]

open access: yesMaterials & Design, 2016
The alternating shielding gas technique is a method of achieving transient arc characteristics during arc welding; however the complex flow that occurs through its use has not been investigated previously. A schlieren system was used to image density gradients that arise when alternating argon and helium shield gases, under varying flow parameters ...

The Effect of Current and Layer in Bimetallic Welding Using J4-AH36 Filler on Tensile Strength

open access: yesLogic, 2022
If filler metal AH36 steel is used in bimetallic welding, it has the disadvantage of oxidation in the weld area. Also, the weld crack is encountered if filler metal J4 stainless steel is used in bimetallic welding.
