Re- baking temperature for SS electrodes

[Sankaran Sp]

Dear Experts,

We are in need to prepare the procedure for "storage and drying conditions for covered arc welding electrodes"

while referring the ASME sec II part C standards - SFA 5.1 Table A3 have temperature for Carbon steel electrodes, SFA 5.5 Table A.2 have temperature for alloy steel electrodes.

For SFA 5.4 S S electrodes no details are available in this standard.

Can you guide me ? how to get the temperature for SS electrodes ? like ( E 410,E430,E 308,E 309Mo,E 316 type electrodes).    

For re drying or re baking of SS electrode,What standards to refer?,kindly give your ideas to complete the procedure.

Regards,

Sankaran.Sp

Coimbatore,India.

Dear friend,

 

As per my knowledge SS electrode does not required any baking. Please correct me if I am mistaken.

It depends on the Type of coating.

 

-15   Basic

-16   Rutile

-17   Rutile Acidic.

 

 

Only Basic electrodes requires rebaking and the temperature is dpended on the Welding consumable manufacturer especially around 250-350degC

 

Rutile and Rutile Acidic depends on the manufacturer around 100-150degC and sometimes it is not needed.

 

Basically the Baking temperature is dependent on the Welding consumable Manufacturer.

 

Thanks & Regards

Mr. Sankaran,

Coated Electrodes tend to pick up moisture due to improper storage or in transits and  may provide 

faulty welds.Electrodes can be maintained perfectly dry over a long period by storing them in a 

dehumidified room or in a room where the electrodes are  kept at 15 deg C. above the ambient 

temperature and  a relative humidity of 45 to 50 %.  With  any other storing condition, re drying them

in a drying oven before its use is a must.

This is especially necessary for hydrogen controlled electrodes which are designed to generate not more

than 15 cc of diffusible hydrogen per 100 grams of weld metal deposit as stipulated by BS:639-1976 in 

order to avoid under bead cracking. in the Heat Affected Zone (HAZ) of heavy thickness and high tensile 

weld-ments.  These electrodes must be dried in a drying oven in the range of 200 -350 deg C. for a hour 

or two  prior to use.  Repeated drying  (more than once) at high temp. will whither the flux coating and not

recommended. They can be stored at 100 deg. C  for a prolonged period if not used  due to some reason

or other. 

Re drying data for the  electrodes generally as  follows:

Type   Temp. range Time

1.  All rultile coated electrodes

     E 6013, E 7013, E XXX 3 type         100 - 110 deg. C 1 hr( if required).

2. All Cellulose Coated electrodes  70 - 80 deg. C 1 hr ( if required)

    E 6010, E 7010, E  XXX 0 type

3. All Low hydrogen / basic coated electrodes 200 - 250 deg. C 2 hrs ( min)

    E 7018, E 8018, E XXX 8 type

    E 7016, E 8016, E XXX 6 type

4. All low alloy, high tensile electrodes 300 - 350 deg. C 2 hrs.(min)

    E 7018-1, E 9018 M, E 10018 M etc.

    E 8018 B 2, E 9018 B 3, E 505-15 etc.

5. All Stainless steel  electrodes like 200 deg. C 2 hrs.  

    E XXX -16 or E XXX -15 type, excluding  

    E XXX - 17 type. 

6. All E XXX-17 type  heavy coated SS  250 - 300 deg. C  2 hrs.

    electrodes

7. Other types and maintenance electrodes.  200 - 250 deg C. 2 hrs.. 

Trust above details will be of help to you.

Sridhar.

Dear Mr.Sankaran,f

[pgoswami]

Hello Shankaran,

 

Please see the guidelines from ESAB & Lincoln ( for educative purposes only).  Typically re-drying temperature for stainless steel electrodes is restricted to 150-200 Deg C Max, or below as recommended by consumable manufacturer.

 

Electrodes in Vacuum Pack or Hermetically sealed packs could be used straight off the pack as shown here. However it's advisable to consult the electrode manufacturer before hand.

 

Thanks.

Dear Mr. Sankaran 

Normally the electrodes those are having low hydrogen flux coating is only required for baking.But for S.S electrodes it doesn't require any baking.Correct me if I am wrong.

Thanks & Regards
