Technical Field

The present invention relates to a welding auxiliary tool.

Background

In the manufacturing process of large ships, pressure vessels and the like and the installation and construction process of large-diameter pipelines, the technology of additionally arranging auxiliary gaskets is generally adopted in the steel plate single-side welding process so as to ensure the welding quality and avoid the defects of incomplete penetration and the like. At present, the gasket for the welding field has been developed and woven into a band-shaped flexible gasket by various heat-resistant material fibers, has the advantages of being resistant to collision, capable of flexibly deforming, good in pasting continuity, convenient to store and transport and the like, gradually replaces part of block-shaped gaskets, and is applied to the welding manufacturing field.

The flexible liner is the same as the block-shaped liner, the aluminum foil with the adhesive is already adhered when leaving a factory, the liner is adhered to the groove on the back surface of the welded steel plate by the aluminum foil with the adhesive when in use, and the liner is cleaned after welding. The aluminum foil with glue of the flexible liner can not be heated in the later period so as to avoid the glue failure, but if the liner needs to be dried and heated before welding after moisture absorption, the liner can be used only after the original aluminum foil is removed and a new aluminum foil is pasted again.
