FIELD: process engineering.
SUBSTANCE: invention may be used for trimming strips in contact butt welding performed at special welding machines used for enlargement of reels and continuous operation of metallurgical plants. Slag and upset metal are removed from top and bottom of strip butts in heated state by introducing built-in lever-type cutter trimmer in between electrodes. Slag and upset metal removed, side surfaces of electrodes are cleaned by cleaning elements secured at every lever of aforesaid trimmer. Top electrodes are lifted to move trimmer levers apart to position whereat cleaning elements get in contact with electrodes. Then trimmer is moved into initial position to make cleaning elements clean electrode sides of adhered particles of fused metal and slag.
EFFECT: higher quality, ease of welding machine servicing.
