It prevents re-oxidation of the surface during soldering, reduces the surface tension of the solder, and enhances soldering performance. The quality of the flux directly affects the quality of electronic products. The following section, provided by a flux manufacturer, explains the functions of flux.

Welding flux manufacturers consider submerged arc welding to be a type of arc welding. A defining characteristic of arc welding is the melting of the base metal. If the molten metal is not protected from atmospheric exposure during the melting process, the weld seam will contain excess oxides, reduced alloying elements, and increased nitrides. To mitigate the detrimental effects of oxygen and nitrogen, it is essential to shield the molten metal from the atmosphere throughout the welding process. The gases and slag produced by the submerged arc welding flux serve to isolate the liquid metal from the surrounding air.

Welding flux manufacturers believe that welding is a highly complex physicochemical process characterized by high reaction temperatures, short reaction times, and the difficulty of achieving equilibrium at any stage of the reaction. Investigating the influence of flux composition on welding process performance remains the most commonly employed approach both domestically and internationally.

According to manufacturers of submerged-arc welding flux, submerged-arc welding is an automated welding process in which a continuous feed of welding wire generates an electric arc beneath a layer of flux. It is also known as submerged-arc automatic arc welding, or simply submerged-arc welding. During welding, the wire feeder of the welding machine automatically advances the welding wire, strikes the arc on the strike plate, and maintains a constant arc length to carry out the weld. In front of the welding wire, granular flux continuously flows out of the hopper and is sprinkled over the joint surface of the workpiece. The arc burns beneath the flux layer, melting the workpiece, the welding wire, and the flux; the molten metal forms a weld pool, while the slag from the melted flux covers the surface of the pool.

According to manufacturers of submerged-arc welding fluxes, such fluxes are generally classified into two main types: fusible fluxes (e.g., HJ350/431) and sintered fluxes (e.g., SJ101/201). Currently, some production lines equipped with submerged-arc welding machines encounter challenges in appropriately selecting between sintered and fusible fluxes. In recent years, sintered fluxes have come to account for approximately 80% of the market share, while the use of fusible fluxes has been declining. In fact, each type has its own advantages and disadvantages; when used correctly, they can help avoid many unnecessary complications.

Submerged Arc Welding Flux Manufacturers: Submerged arc welding fluxes are generally classified into two main types: fused fluxes (such as HJ350 and HJ431) and sintered fluxes (such as SJ101 and SJ201). Currently, some welding units employ submerged arc welding equipment, which presents challenges in the application of sintered fluxes compared with fused fluxes. In recent years, sintered fluxes have come to account for 80% of the market share, while the use of fused fluxes has steadily declined. In fact, each type has its own advantages and disadvantages; when used appropriately, they can help avoid many unnecessary complications.

Submerged-arc welding flux manufacturer: The welding process performance and the chemical-metallurgical properties of the flux are among the primary factors that determine the chemical composition and mechanical properties of the weld metal. Even when using the same welding wire and the same welding parameters, different fluxes can result in significantly different weld performance. Whether for low-carbon steel or low-alloy steel, a single welding wire can be appropriately matched with a variety of fluxes.
