The invention relates to a method for preventing welding spatter attachment of the inner wall of a pipe fitting, and belongs to the technical field of welding. According to the technical scheme, a collecting barrel (1) is moved and stretches into a pipe fitting (6) to be welded through a clamping and moving device (2), a collecting hole (3) corresponds to the laser perforation position, the position of the collecting barrel (2) is adjusted, the center of the collecting hole (3) is right opposite to the center position of a welding seam (4), and welding spatter and smoke dust generated on the back face of the welding seam during laser welding or laser-arc hybrid welding are collected. The collecting barrel has the beneficial effects that by arranging the collecting holes, splashing particles can be effectively prevented from rebounding and being attached to the inner wall of the pipe fitting to be welded, it is ensured that all splashing and smoke dust are collected in the collecting barrel, and therefore the
