Welding backing dress patch dolly for steel construction U-shaped floor
Technical field
The present invention relates to bridge welding technical field.It is more particularly related to a kind of be used for steel construction U-shaped floor
Welding backing dress patch dolly.
Background technology
The design requirement of the U-shaped floor angle welding on most of steel constructions is that depth of penetration is not less than thickness of slab both at home and abroad at present
80%, and must not weld Lou, surface is smooth even suitable.But to reach this requirement, need to be to the assembly technology in production process and weldering
Connect technique to be strict with, existing welding method is in welding process because fit-up gap error is big and back of weld does not protect
The factors such as measure, all it is very easy to cause workpiece burn-through or does not reach design fusion penetration requirement, so that it is excessive to do over again, quality can not
Ensure, and because steel construction U-shaped floor weld seam back is all small space, can not manually carry out pasting pad protection operation, when
A kind of dolly that welding backing dress patch can be carried out in small space of lower design, it appears very meaningful.
The content of the invention
It is an object of the invention to solve at least the above, and provide the advantages of at least will be described later.
