Spot welding - WikiMili, The Best Wikipedia Reader
spot welding (or resistance spot welding) is a type of electric resistance welding used to weld various sheet metal products, through a process in which contacting metal surface points are joined by the heat obtained from resistance to electric current.
In addition to these sizes, some manufacturers also offer .020” (0.5mm) and ¼” (6.4 mm) tungsten. The most common length is 7.00” (175 mm). Tungsten is normally sold in boxes of 10 pieces. Current Ranges: Refer to Table A.2 of AWS A5.12M/A5.12:2009 Specifiion for Tungsten and Oxide Dispersed Tungsten Electrodes for Arc Welding and Cutting.

Welding repairs - achieving strong welds
General purpose electrodes, those rated E6012 or E6013, are useful for welding mild steels in most situations. However, some electrodes are designed for overhead use, others for downward welding. Even with general purpose electrodes, using an electrode, that is intended for downward welding, in an overhead position can result in poor deposition of weld metal and a weld that is liable to break.
