Causes of Welding "Hot Cracks" and Countermeasures

Hot cracks are generated at high temperatures during the welding process, also known as high temperature cracks. Thermal cracks generally appear in the weld, sometimes in the heat-affected zone, and can occur inside the material or on the surface of the material. It is a defect that must be avoided in welding.

Surfacing Welding Technology for Restoration of Bulldozer Reduction Gear by Manual Arc Welding

Overlay welding is a welding process that deposits a layer of wear-resistant, heat-resistant, and corrosion-resistant metal layers on the surface or edge of the workpiece. Overlay welding can repair old metal parts, so as to prolong the service life of parts and reduce costs. This paper takes manual arc welding surfacing welding bulldozer reducer gear as an example to illustrate this kind of repair process.

Precautions for using agglomerated welding flux

Agglomerated welding flux combines all the raw materials to produce a dry mixture that is then bonded by a liquid binder such as potassium silicate or sodium silicate. The mixture is baked at low temperatures and sieved to attain a specified particle size.

Precautions for using and storing welding flux

(1) The residue after welding flux soldering is corrosive to metal, so it should be cleaned with water or wiped with a damp cloth immediately after tinning. (2) Do not get into eyes or mouth, please rinse with water after contact with skin. (3) welding Flux products are corrosive to metals.

Storage and Handling of Welding Fluxes

Phoenix welding fluxes are delivered in protective packaging to meet the needs of normal transportation, handling, and storage. Attention should be paid to ensure that transportation and storage conditions are dry and appropriate for this type of product. If the original package has been open for more than 24 hours, is damaged, or if it has been stored for extended periods then the welding flux should be re-dried before welding.

A bauxite supplier provides a manufacturing method for a conveying device for bauxite production

The utility model relates to the technical field of bauxite, in particular to a material conveying device produced by bauxite supplier bauxite. Bauxite, also known as bauxite or bauxite, is mainly composed of alumina, which is hydrated alumina containing impurities. It is an earthy mineral, mostly white or off-white. Bauxite is extremely difficult to melt, insoluble in water, but soluble in sulfuric acid or sodium hydroxide solution, and is mainly used for aluminum smelting and refractory production. The existing material conveying device has the disadvantages of serious dust flying during feeding, great environmental pollution, impact on workers' health, and inconvenience to use.
