Abstract
The shielded metal arc welding is mostly popular for fused injection method of metal to metal. The spatter particle appears during the metal arc welding, and then adheres so strongly on the surface of welded plate. Therefore, the commercial anti-adhesive agent is coated on surface of the plate before welding. However, the agent from organic synthesis has several problems, such as environmental influence, stink and expensive. The purpose of this study is to develop the spatter anti-adhesive agent containing a kind of volcanic ash called “Shirasuballoon” which brings the environmental merit, no stink and low cost. In present study, the effect of unique anti-adhesive agent for metal arc welding was reported and discussed based on observation of boundary between spatter particle and metal plate, and mechanical inspections using tensile and impact testing machine.
