| E3XX-16
and E3XX-17 are both recommended for flat groove position and horizontal
fillet. |
|
| Electrodes -16, -17 both produce fine spray mode, -17 is
not recommended for other than flat position. |
| Electrode -16 can be used for all position and is common
for overlay, as it provides smoother surface finish than -17. |

-17 also used where minimum clean up is desired, produce good appearance and

| Good to know
tips when welding Stainless Steel On The Go |
|
|
|
|
|
|
|
|
|
| Stainless
steels are commonly divided into the following general groups: |
|
|
| (1) Chromium
Martensitic (4XX Series) |
|
|
|
|
| (2) Chromium
Ferritic (4XX Series) |
|
|
|
|
| (3) Austenitic
(2XX Series, Cr-Ni-Mn and 3XX Series Cr-Ni) |
|
|
|
| (4) Precipitation-hardening (grades are assigned
designations based on their Cr and Ni contents) |
| |
|
|
|
|
|
|
| For
low or high temperature, corrosive or any critical applications always
confirm electrode choice |
| with wire
manufacturer. |
|
|
|
|
|
| |
|
|
|
|
|
|
| For
similar metal joints, use filler metal of matching composition, |
|
|
| (e.g.: weld
304L with 308L wire), (316 with 316, and 308L with 308L wire). |
|
|
| |
|
|
|
|
|
|
| Dissimilar
joining, use the lower alloyed of the two base metals (e.g. use 308 to join
304 to 316). |
| |
|
|
|
|
|
|
| If
both metals are low carbon (3XXL), then use low carbon, 3XXL filler metal as
well. |
