UTP LEDURIT 61 Hardfacing Electrode

UTP LEDURIT 61 is a rutile-basic coated hardfacing stick electrode suited for highly wear resistant claddings on parts subject to strong grinding abrasion and medium impact. It has excellent welding characteristics with easy slag removal and produces a homogeneous seam that usually does not require finishing. The pure weld deposit has a hardness of around 60 HRC. It is recommended to use a cushion layer of UTP 630 for multipass applications to prevent hardening cracks. UTP LEDURIT 61 can be used in all welding positions with DC or AC current.

UTP LEDURIT 61

rutile-basic coated hardfacing stick electrode

Classifications
DIN 8555 EN 14700 AWS A5.13
E 10-UM-60-GRZ EZ Fe14 ~ E FeCr-A 1
Characteristics and field of use
UTP LEDURIT 61 is suited for highly wear resistant claddings on parts subject to strong grinding
abrasion combined with medium impact, such as conveyor screws, scraper blades, digging teeth,
mixer wings, sand pumps. Also as a final layer on crusher jaws.

Welding properties
UTP LEDURIT 61 has excellent welding characteristics and a very easy slag removal. The
homogeneous and finely rippled seam surface does, for most applications, not require any
finishing by grinding.

Hardness of the pure weld deposit approx. 60 HRC

Welding instruction
Hold stick electrode as vertically as possible, keep a short arc. Preheating is in general not
necessary. On multipass-applications a cushion layer with UTP 630 is recommended in order to
prevent hardening cracks in the weld deposit. Redry stick electrodes that have got damp for
2h/300° C.
