Abstract

The present invention relates to a novel consumable guide nozzle suitable for use in the electroslag welding.

Claims

1. A method for preparing consumable guide nozzles for use in electroslag welding comprising:

a. blending together fine metal particles and a liquid heat hardening adhesive;

b. coating the outer surface of a hollow metal guide tube open at both ends with a quantity of said blend at least equal in weight to the weight of the guide tube;

c. compressing said coated guide tube;

d. heating said compressed coated guide tube until said adhesive hardens, and

e. recovering a consumable guide nozzle suitable for use in electroslag welding comprising a hollow metal guide tube having a coating of fine metal particles adhered to the outer surface thereof.

2. A method according to claim 1 wherein said compressed coated guide tube is shaped to the desired shape prior to being hardened.

3. A method according to claim 1 wherein said heat hardening adhesive is sodium silicate.

4. A method according to claim 2 wherein said heat hardening adhesive is sodium silicate.
