Description

technical field [0001] The invention relates to a welding auxiliary tool. Background technique [0002] In the manufacturing process of large ships and pressure vessels and the installation and construction of large-diameter pipelines, the single-sided welding process of steel plates generally adopts the technology of adding auxiliary liners to ensure welding quality and avoid defects such as incomplete penetration. At present, the pads used in the welding field have been developed into flexible pads woven into ribbons using various heat-resistant fibers, which have the advantages of not being afraid of bumps, flexible deformation, good sticking continuity, and convenient storage and transportation. Instead of some block pads, it is applied to the field of welding manufacturing. [0003] The flexible liner is the same as the block liner. It has been pasted with adhesive aluminum foil when it leaves the factory. When in use, the liner is adhered to the groove on the back of ...

AI Technical Summary

Problems solved by technology

The glued aluminum foil of the flexible liner cannot be heated later to avoid glue failure. However, if the liner needs to be dried and heated before welding after absorbing moisture, the original aluminum foil can only be removed and a new aluminum foil can be re-pasted before use.

Moreover, pasting aluminum foil on the liner not only wastes materials and increases process costs, but also aluminum foil remains on the steel plate after welding, which brings difficulties to later cleaning
