Welding work is performed when installing pipes to carry gas, oil, etc., but the spatter generated during this process adheres to the walls, floors, or structures of buildings, factories, and requires a lot of man-hours to remove. To prevent this, the walls and floors are covered with tin plates, flameproof sheets, and anti-spatter cloth. However, in the case of a tin plate, it is necessary to cut it to match the shape of the part to be covered, and in the case of a flame retardant sheet or anti-spatter cloth, there are problems such as the part where the slag adheres burns out and holes form. Ta.

ノロ５の飛散付着状況を調べた。The slag adhesion prevention sheet) a obtained as described above is pasted on the floor surface 1 and wall surface 2 as shown in FIGS. 1 and 2, and from the floor surface 1,
WEL3 manufactured by Nippon Welding Rondo Co., Ltd. at a distance of 150 mm and 100 m from wall 2.
Welding of stainless steel pipe 3.4 was carried out using a 08 welding rod, and the state of scattering and adhesion of slag 5 was investigated.
その結果、実施例は、壁叡に対し飛散するノロ５は、は
