Almost all electrodes have a series of numbers to tell #1 what the tensile strength of the weld will be, #2 what electrical current to use, #3 what position/s it can be used in (ie: flat, vertical etc.) Ex. E - 7018. E = electrode, 70 = 70,000 lbs tensile strength, 1 = all positions, 18 = AC or DC reverse polarity current. (welding lead +)

What is the difference betweenTig wire stick welder?
a stick welder needs to replace his electrode regularly and the flux coating is on the outside while a tig machine constantly feeds the wire and the flux is produced by a filler gas
Which electrode is using for cs and ss combination weld?
309l
How do you calculate diameter of electrode for an electric arc furnace?
i don't know please give me the answer
Is a wire feed a mig or tig?
The wire feed welder is a MIG welder.
Who invented electrode?
Which scientist coined the term Electrode?
What does welder do?
Welder as in the person: A welder joins metal together using Oxy-fuel or more commonly Arc processes. Welder as in the Machine: A welder converts electricity from your home/workplace and turns it into suitable voltage and amperage for welding operations. That is to melt the base metal and add filler metal (electrode) In the case of gouging the arc is transferred between the carbon electrode, melts the base metal and a stream of compressed air carries the molten puddle away. A Welding machine may also be a fuel driven machine often used on job sites away from electrical connections.

What does the welder do?
Generally the title of 'fitter' is applied to the person who does the layout, preparation and positioning of parts to be welded. They may also do the cutting of the parts to be assembled and the tacking the parts in place. A 'welder' then comes behind the fitter and welds the parts together. A 'fitter and welder' does the entire job and all the aspects of it.
What is the name of non consumable electrode?
There are no , non -consumable electrodes, there are slower consumed electrodes, as in TIG (tungsten inert gas) welding in which a Tungsten electrode is used , and in the hands of a very skilled welder , last the longest of all electrodes , but are in the end consumed.
Is TIG Welder is also considered as Co2 welder?
No , although Co2 may be used , along with other gasses , a welder using this process is not considered a Co2 welder . TIG stands for tungsten Inert Gas , so the welder is considered / called a TIG Welder.
Explain welder polarity?
In welding, polarity refers to the direction of the electrical current flowing through the welding circuit. In DC welding, there are two types of polarities: Direct current electrode positive (DCEP): Here, the electrode is connected to the positive terminal of the power source, which results in more heat at the workpiece. Direct current electrode negative (DCEN): This polarity is when the electrode is connected to the negative terminal of the power source, resulting in more heat at the electrode tip.
What Rods should i use with an ac welder?
For an AC welder, it is best to use electrodes specifically designed for AC current, such as 6011 or 6013 electrodes. These rods provide good arc stability and smooth welding characteristics when used with an AC welder. Be sure to follow the manufacturer's recommendations for electrode selection based on the thickness and type of metal you are welding.
What does the term single hand welder mean?
A "single hand welder" is any person welding on a job that is not using their own personal equipment. I.E., welding with a company welder or rented welder until you can afford to buy your own welder.
Which electrode is using for cs and ss combination weld?
309l
How should the values found using the zinc electrode as a standard compare with those based on the standard hydrogen electrode?
When using the zinc electrode as a standard, the values obtained will be relative to the standard hydrogen electrode (SHE). The potential difference between the two electrodes at a given condition can be used to calculate the standard electrode potential of the zinc electrode. This potential difference is due to the different standard hydrogen electrode potential (0 V) and standard zinc electrode potential (+0.76 V).
How do you use your portable welder to weld aluminum?
To weld aluminum with a portable welder, you would typically need a TIG (Tungsten Inert Gas) welder as it is best suited for welding aluminum. Ensure that you have the appropriate welding electrode and shielding gas for aluminum welding. Adjust the settings on the welder according to the thickness of the aluminum and begin welding by creating a stable arc and using a consistent motion to create a clean weld bead. Practice proper technique and ensure you have adequate ventilation when welding aluminum.
Difference between reference electrode and indicator electrode?
A reference electrode is used to establish a stable electrochemical potential for comparison within a measurement system, while an indicator electrode is used to respond to changes in the analyte concentration being measured. Reference electrodes provide a fixed potential, whereas indicator electrodes change their potential in response to the analyte's concentration.
