Description

Automatic submerged arc welding slag collecting device and submerged arc welding vehicle

Technical Field

The utility model belongs to the technical field of welding slag collecting equipment manufacturing, and particularly relates to an automatic submerged arc welding slag collecting device and a submerged arc welding vehicle.

Background

In the process of submerged arc welding, the welding flux flows out from the hopper and is uniformly deposited on the assembled workpiece, and the welding wire is fed into a welding arc area by a wire feeding mechanism through a wire feeding roller and a contact nozzle. Two ends of the welding power supply are respectively connected with the contact tip and the workpiece. The wire feeder, flux hopper, and control panel are typically mounted to a carriage for movement of the welding arc.

The welding process is automatically controlled by operating a button switch on the control panel. During welding, the workpiece is covered with a layer of granular flux of 30-50 mm thickness, and the continuously fed welding wire generates an electric arc between the lower part of the flux layer and the workpiece, and the heat of the electric arc melts the welding wire, the workpiece and the flux to form a molten metal pool which is isolated from the air. As the welder automatically moves forward, the arc continuously melts the forward weldment metal, welding wire and flux, the edge behind the molten pool begins to cool and solidify to form a weld bead, and the liquid slag then condenses to form a hard skull. The unmelted flux can be recycled, so the slag collection on the weld after submerged arc welding is of great importance, but at present there is no tool dedicated to the slag collection of submerged arc welding.
