What diameter electrode should be used?
Generally the size of the electrode that should be used depends on the thickness of the part to be welded. For thin metals the electrode is only slightly larger than the metal to be welded. For example if a plate is of 2.0 mm thick the electrode of 2.5 mm should be used.
How is the proper size electrode determined for a specific welding project?
To determine the correct current type for a particular electrode, refer to the fourth digit of the AWS classification, which represents the type of coating and type of compatible welding current (see Figure 1). The type of current you use also influences the penetration profile of the resulting weld.
What is electrode diameter dependent on?
Electrode size – Electrode size should depend on the electrode type, welding position, joint preparation, base metal thickness, and skill of the welder.
What is the range of normal electrode size in welding?
ELECTRODE SIZE AND AMPS USED
| ELECTRODE DIAMETER (THICKNESS) | AMP RANGE | PLATE |
|---|---|---|
| 1/16″ | 20 – 40 | UP TO 3/16″ |
| 3/32″ | 40 – 125 | UP TO 1/4″ |
| 1/8 | 75 – 185 | OVER 1/8″ |
| 5/32″ | 105 – 250 | OVER 1/4″ |

What is the importance of correct electrode size?
The correct choice of electrode size involves consideration of a variety of factors, such as the type, position, and preparation of the joint, the ability of the electrode to carry high current values without injury to the weld metal or loss of deposition efficiency, the mass of work metal and its ability to maintain …
How many different diameters are electrodes produced in?
5 Electrodes – Electrodes for gas tungsten arc welding are available in diameters from . 010″ to 1/4″ in diameter and standard lengths range from 3″ to 24″. The most commonly used sizes, however, are the . 040″, 1/16″, 3/32″, and 1/8″ diameters. 2.3.
Are all E6013 electrodes the same?
Difference between E6012 & E6013 The main difference between the E6012 and E6013 electrodes is that the E6012 covering contains sodium, while the covering of E6013 contains potassium. Both E6012 & E6013 run under direct current (DC+) but only the E6013 is suitable for running under alternative current (AC) & DCEN.
