The angle of the electrode, the speed of the electrode used to weld and the size of the electrode.
what characteristics does the weld bead have when weaving the electrode
It varies from 3 inches to 13 inches. The electrode type, type of weld, and position of weld all determine how far you can get done with a single rod
motion of the electrode causes different pattterns in th formation ofthe cooling weld puddle. You can alter the weld patter by changing the electrode motion,,ex: motion straight across the weld zone and dropping electrode position say (1/8th inch) produces given pattern..same pattern with a slight upward motion at edges of weld zone another pattern...etc etc
nickel
Electrodes with too much moisture may lead to cracking or porosity.
309l
A narrow, straight weld bead that is created by moving the SMAW electrode straight along the weld joint. A quality stringer bead should have good tie-in on both sides of the weld.
6010 is a high cellulose sodium based electrode, which can be used to weld carbon steel pipes.
Tig is always done in straight polarity, i.e. electrode negative. reason: almost 2/3rd of the heat is generated in positive terminal of weld, in this case the base metal and the rest in the negative terminal, in this case the tungsten electrode. Also you don't want to deposit the tungsten electrode in the weld, do you?
the rod will simply stick to the material being welded!
The tungsteng electrode, because this one not is a filler metal in this process. The individual may be asking what metal can you not weld using the TIG process. In that case cast iron, zinc (including zinc coated metals), lead and any metal with a low melting temperature would be the answer.
