adispersive spectroscopy (EDS); the mechanical properties were measured by microhardness test, tensile test, and impact test; the corrosion[translate] aThe corrosion current density of TIG weld metal is higher than that of MIG weld metal in a 3.5wt% NaCl solution. Galvanic corrosion[translate]...
The arc is a basic requirement for MIG/MAG welding. It is created by closing the circuit between the electrode and the workpiece. The wire electrode almost always has positive polarity. During the arc phase, the material transfers dynamically from the consumable electrode to the workpiece. This ...
Strength:Spot welding is not a very strong welding process, as it only creates a small weld nugget that may not be able to withstand high loads or stresses. The strength of the weld depends on the size, shape, and number of the weld nuggets, as well as the quality of the metal sheets...

In manual metal arc welding, the amperage is the most important parameter for the quality of the connections. It must therefore remain as constant as possible, even if the arc length changes. In order to ensure this, power sources for electrode welding always have drooping characteristics. ...
spatter-free weld seams are required. TIG welding is suitable, among other things, for stainless steels, aluminum and nickel alloys as well for thin sheet metal made of aluminum and stainless steel. It is used in pipeline and container construction, in portal construction and in aerospace ...
Beginners have a clearer view of the MIG weld: If you can see the weld, you'll learn quickly how to control the weld pool. Since MIG welding with gas produces an arc with fewer sparks and smoke, it's possible to see the weld puddle and observe any effects that adjustments or technique...
You can use cast iron, hard-facing alloys, stainless steel, and numerous carbon steels with the flux core arc welding process. Nonetheless, you cannot weld exotic non-ferric metals like aluminum with this welding approach. How Do You Transform a MIG Welder to Flux Core Arc Welding?
