Centralized dust collection in wear-resistant surfacing workshop

Centralized dust collection in wear-resistant surfacing workshop
On the surface of worn metal parts (such as rolls, shafts, gears, cold stamping dies, valve sealing surfaces, high-speed steel blades, bulldozer blades, excavator teeth, propellers, etc.) deposit wear-resistant, corrosion-resistant or other special performance metals Layer welding method. Almost all fusion welding process methods can be used for surfacing welding. Manual arc welding, submerged arc welding and plasma welding are commonly used for surfacing.
Since the open arc self-protection process is adopted, a large amount of smoke and dust will be generated during the surfacing process, which will affect the production environment and the health of the operator. Therefore, each welding torch is equipped with a smoke pipe, and the smoke pipes are combined and discharged by the fan. The purpose is to automatically remove most of the welding fumes to the outdoors, thereby reducing the impact on the environment and operators.

Based on the high temperature properties of surfacing welding, the system components of this welding fume control project include pipes, powerful fans, dust collectors, filter elements and control devices. Among them, one side of the high temperature hose is connected to the air pipe fixed on the cross arm. , The other side is connected into the main pipeline, which does not affect the lateral and longitudinal movement of the welding torch. The Welding Gun is equipped with a high-temperature dust-absorbing hood, which is directly collected at the dust-producing point, so as not to generate smoke and dust diffusion, and achieve the ideal dust collection effect.
