Methods for measuring welding process parameters
Thread Content
I would like to ask the welding experts in the group: when conducting welding process evaluations and welding test pieces, how do you determine parameters such as current, voltage, and welding speed? How is the welding wire energy calculated? (Manual welding, such as GTAW, SMAW).
The welding current is related to factors such as the welding method for the base material and the diameter of the welding material. For example, in manual welding, the welding current is generally set at 3-4 times the diameter of the electrode; it also depends on the welding position – a higher current can be used for horizontal welding, while a slightly lower current is sufficient for manual TIG welding. The value of the current is adjusted according to factors such as the fluidity of the molten pool in the material
