Description
Technical field
The invention belongs to welding wire technology fields, and in particular to a kind of anti-stomata self-protection flux-cored wire.
Background technique
Welding material of the self-protection flux-cored wire as a kind of efficient and suitable outdoor work, in ship, drilling platforms, stone
The welding fields such as oil-piping, container are by favor.But self-protection flux-cored wire there are technological parameter adaptability small, flue dust compared with
Greatly, operative weldability and the deficiencies of unstable joint mechanical property, is somewhat prohibitive its application.Due to the knot of flux-cored wire
Structure is including medicinal powder, outside, welding process easily causes molten drop, molten bath stage to generate stomata because protecting deficiency to sheetmetal.Such as
The design of fruit formula it cannot be guaranteed that molten drop and molten bath stage have sufficient protective gas and liquid-solid transformation stage nitrogen, hydrogen,
Oxygen and carbon monoxide etc. cannot be overflowed or be converted completely, and it is easy to appear stomata or pin holes for weld seam, and stomata is unacceptable
Welding defect.
Summary of the invention
The purpose of the present invention is to provide a kind of anti-stomata self-protection flux-cored wires, to solve problem above.
