RE: [MW:24869] E6013 not Applicable for High Thickness material

Not saying E6013 could not be used for welding thicker sections but there are significant downsides to doing so. 

 

First, you sacrifice around 15% off the top on tensile strength compared to an  E70XX (XX=15,16,18) electrode.  Depending on design/application, you will require greater thickness for the same loading.  If subjected to fatigue loading, the greater thickness required will have an adverse effect on fatigue life.   

 

Secondly the shallow penetration, for which this electrode was designed, can cause problems with lack of fusion defects at the weld/pass root and/or slag inclusions at the root.  These can be prevented by close attention to weld preparation and weld technique but are more easily avoided by using an electrode with greater penetration.

 

Ignoring sheet metal fabrication or poor fit up issues, the only real advantage to use of E6013 are the lower skill level required to make visually appealing welds.   Visual appearance of the finished weld should be excellent;  flat, smooth, even ripples.

 

In my section of the country, one will find the E6013 is often referred to as "farmer rod".  You can read into to that whatever you like.

 

Enjoy.

I would never recommend E6013 for main load bearing members welding unless the designer has considered very high safety structures. For steel structures under EuroCode 3 almost nobody is using E6013. E7018 or FCAW with E71T-1 for example. Some specs do not allow at all GMAW for critical structures

Dear KG P,

 

E-6013 is generally recommended for general purpose welding as far as overall quality is concerned  .that doesn't means E-6013 not suitable for high quality welding.

do u mean that u can not get RT quality in 6013? for lesser thick also

why u are not using 6010 for entire thickness or why  are not using 7010,

Dear Amit,

 

 

E- 6010 - Cellulose flux having deep penetration property , recommended for root pass welding of cross country pipe lines.

E-7018  - Basic Coated , Low hydrogen ,iron powder type electrodes having more tensile strength recommended for  filler                     and cover pass welding (after root and hot pass by GTAW)  piping fabrication.

E-6013 -  Rutile (titania)  flux is recommended for general purpose welding (say Gate /grill fabrication).

 

first two is considered where radiographic quality weld is required.
