Guide bar for a saw chain

A guide bar for a saw chain, said guide bar comprised of:

• a sword-shaped base member made of solid material and having a front end with a deflection area for a saw chain and a rear end for connecting said guide bar to a drive unit;
• said base member having outer lateral surfaces extending from said front end to said rear end and having a longitudinal central axis extending from said front end to said rear end;
• said base member comprised of a main body and a separate front member welded to said main body so as to have a welding seam on at least one of said lateral surfaces;
• said base member having an edge with a continuous circumferential groove for receiving and guiding the saw chain;
• said separate front member having a base surface and said main body having an end face;
• said base surface abutting said end face and defining a parting line therebetween;
• said parting line covered by said welding seam connecting said main body and said separate front member;
• said welding seam extending over substantially the entire length of said parting line;
• wherein said end face has a plurality of recesses opening in a direction toward said base surface and wherein said base surface has a plurality of projections matching and engaging said recesses such that said end face and said base surface have a wave-shaped contour;
• wherein said recesses and said projections are arranged on a circular arc described about a center point of said separate front member.

• said base member having an edge with a continuous circumferential groove for receiving and guiding the saw chain;
• wherein said separate front member is comprised of at least one side plate having an outer plate surface forming part of said outer lateral surfaces;
• wherein said separate front member has a base surface and said main body has an end face, said base surface abutting said end face and defining a parting line therebetween, said guide bar further comprising a flat strip placed onto said parting line between said side plates and said main body for covering said parting line, said flat strip welded onto said outer lateral surfaces such that said welding seam extends on said outer lateral surfaces on said main body and on said outer plate surfaces of said side plates.
