Welding method

A method for welding a first hose end at a hose joint with a second hose end in a closed seam that extends on a circumference of the first hose end, the method comprising the steps:

• applying a protective layer at the joint to an inside of the first hose end;
• pushing the second hose end beyond the joint over the first hose end;
• pressing the first hose end and the second hose end together flat at the joint between two first clamping jaws that are moved towards each other;
• welding the first hose end and the second hose end together by the first partial seams while pressed together flat to form a partially welded hose joint, wherein the protective layer prevents a welding of the inside of the first hose end;
• releasing the first hose end and the second hose end from the two first clamping jaws after welding the two first partial seams and erecting the partially welded hose joint from being pressed flat;
• pressing the first hose end and the second hose end at the partially welded hose joint together again flat transversely to the first partial seams by two second clamping jaws;
• and
• welding the first hose end and the second hose end in two second partial seams while pressed together flat transversely to the first partial seams so that the first partial seams and the second partial seams form the closed seam at a completely circumferentially welded hose joint.
