Description

Welding flux baffle device suitable for submerged arc welding build-up welding

Technical Field

The utility model relates to the field of welding, in particular to a flux blocking device suitable for submerged arc welding overlaying.

Background

In order to ensure the working efficiency and the processing quality after the rotating roller is worn, the worn position of the rotating roller is required to be subjected to surfacing repair, submerged arc surfacing is a common surfacing repair process, in the welding process, a layer of granular flux with the thickness of 30-50mm is covered on a welded part of a workpiece, and a metal molten pool is formed under the action of a welding machine. As the welder moves forward automatically, the welder metal and flux in front of it are continuously melted, and the edges behind the molten pool begin to cool and solidify to form a weld, and the liquid slag then condenses to form a hard slag shell. However, because the repaired roll surface is arc-shaped and has a slight rotation phenomenon, when submerged arc welding overlaying welding is carried out, welding flux is extremely easy to slide from two sides, the protectiveness of the welding flux to a molten pool is greatly reduced, the forming effect of a welding surface is further affected, in order not to affect the welding effect, repeated addition of the welding flux is needed, an operator needs to use a tool to carry out manual blocking at present, so that each person can only operate one submerged arc welding device, the consumption of the welding flux is increased additionally, and the repairing efficiency is reduced while the manpower and material resources are wasted.

In this scheme, the area that the fixed plate constitutes is not big and only leaves a passageway, and the baffle moves along with the welder, and in the removal in-process, if the roll surface takes place to turn, can make the solder flux that does not have the baffle position drop, can not effectually play the effect of stopping to the solder flux, consequently needs a device that can effectually stop the solder flux landing.
