What else can I help you with?
Three condition of electrode that could affect weld bead shape in sheilded metal arc welding?
The angle of the electrode, the speed of the electrode used to weld and the size of the electrode.
What effects does shortening the electrode extension have on weld penetration?
Shortening the electrode extension typically reduces weld penetration. This is because a shorter electrode extension results in a smaller arc length, which reduces the heat input into the weld and leads to less penetration. It is important to maintain the proper electrode extension to achieve the desired weld penetration.
If the electrode used in welding has a moisture what effect will it have on the weld?
Moisture in the electrode can cause porosity in the weld, as the moisture turns into steam during the welding process, creating gas pockets. This can weaken the overall integrity of the weld and affect its mechanical properties. It is important to keep electrodes dry to prevent these issues.
What is a leading electrode angle for in welding?
what characteristics does the weld bead have when weaving the electrode
What inches you can weld with one 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
What type of electrode can you weld cast iron with?
nickel
What characteristics of the weld bead does the weaving of the electrode cause?
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
If electrode use in welding has moisture what effect will it have on the weld?
Electrodes with too much moisture may lead to cracking or porosity.
Which electrode is using for cs and ss combination weld?
309l
What is a straight weld bead on the surface of a plate with little or no side to side electrode movement called?
A straight weld bead on the surface of a plate with little or no side-to-side electrode movement is called a stringer bead. It is a type of weld bead characterized by its uniform and straight appearance, typically achieved through consistent and controlled forward movement of the welding electrode along the joint.
How do you weld 6010?
6010 is a high cellulose sodium based electrode, which can be used to weld carbon steel pipes.
Do you tig weld on dc straight or reverse polarity?
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?
