PROBLEM TO BE SOLVED: To provide a welding spark scattering prevention tool capable of preventing scattering of a spark in welding, easily carriable, and allowing an operator to execute installation and replacement to a welding member.SOLUTION: The welding spark scattering prevention tool comprises a sheet-like main body and a magnet equipped in the main body. The main body has fire resistance, can inject-exhaust air, expands in a sheet shape when injecting the air, and can be folded up when exhausting the air. The main body of expanding in the sheet shape is fixed at its end part in the crossing direction with a welding line by attracting the magnet attached to the main body to a welding member, and at least the side of a welding place is enclosed by the main body. The magnet is provided by two or more, and can be attracted to both respective welding members. A part of the main body is provided with an air injectable-exhaustible tube and an arm. The main body expands in the sheet shape when the tube swells by injecting the air, and can be folded up by exhausting the air from the tube. The arm projects to the front side of the main body when injecting the air, and can be folded up when exhausting the air. 【課題】 溶接時の火花の飛散を防止でき、手軽に持ち運びができ、溶接部材に溶接作業員が設置や付け替えを行うことができる溶接火花飛散防止具を提供する。【解決手段】 シート状の本体と本体に装備する磁石を備え、本体は耐火性を備え、注排気可能であり、注気されるとシート状に広がり、排気されると折畳み可能となり、本体に装着した磁石を溶接部材に吸着することにより、シート状に広がっている本体を溶接線に交差する方向にその端部で固定して、本体により溶接箇所の少なくとも側方を囲めるようにした。磁石を二以上設けて双方の溶接部材の夫々へ吸着できるようにした。本体の一部に注排気可能なチューブ及びア-ムを備え、本体はチューブが注気されて膨らむとシート状に広がり、チューブが排気されると折畳み可能となり、ア-ムは注気されると本体の先方に突出し、排気すると折畳み可能となるようにした。【選択図】図１
