Choose an Aggressive Flux for Stainless Steel SolderingĬhoosing the right flux is the most important step in soldering stainless steel. It’s best to solder right after cleaning before any other dirt or film attaches to the steel surface.Ģ. Remove the oil and grease with a cleaning solvent and use a stainless steel brush (or even a wire brush) to achieve a clean, metallic surface. Make sure to do a thorough clean of the steel surface, particularly in the joint area. It is important, however, to choose the right temperature, heating unit, and flux to have a strong connection.Īlthough the oxide film that presents itself in stainless steel can make it more difficult to solder, it can be completed if the right techniques are used.īelow are 5 Steps on How to Effectively Solder Stainless Steel Wire and More: Soldering is an effective way to join stainless steel in roofing applications. Lead-Free Wire Solder for Industrial Soldering Lead-Free Wire Solder for Electronic Assembly Lead-Free Solder Bar for Soldering & Tinning Electronics Lead-Free Solder Bar for Industrial Soldering & Tinning To avoid this problem, it is recommended to clean the spray system every week and replace the flux with precipitates.Solder Bar & Solder Wire - Leaded & Lead-Free When flux is used for a long time, a small amount of sediment will accumulate at the bottom of the sealed tank, which may lead to clogging of the spraying system of the wave oven.When using flux in sealed cans, pay attention to the performance of the wave crest furnace and the characteristics of the product to reasonably adjust the spray volume and spray air pressure.Solvent flux is a flammable chemical material, should be operated in a well-ventilated environment, and away from fire, avoid direct sunlight.

Flux preheating temperature, single panel board bottom recommended temperature: 75-105 ℃ (single panel board surface recommended temperature: 60-90 ℃), double panel board bottom recommended temperature: 85-120 ℃ (double panel board surface recommended temperature: 70-95 ℃).The recommended amount of flux for single panel is 25-55ml/min, and the recommended amount of flux for double panel is 35-65ml/min. The amount of flux coating depends on the needs of the product.After long-term storage of flux, its specific gravity should be measured before use and adjusted to normal by adding diluent.The best storage temperature: 18 ℃ -25 ℃, the best storage humidity: 75% -85%. The sealed storage period is six months, please do not freeze to store the product.Non-stick, non-stick hands after welding, welding joints are not easy to pull the tip.After welding residue is easy to remove, and has no corrosion, non-hygroscopic and non-conductive properties.Welding does not produce welding bead spatter, and does not produce toxic gas and strong irritating odor.Viscosity and specific gravity than the solder is small, viscosity will make the infiltration diffusion difficult, the ratio is large can not cover the surface of the solder.infiltration and diffusion faster than the melted solder, usually requires expansion at about 90% or more than 90%.Lower melting point than the solder, before the solder melts, the flux should be melted first, in order to give full play to the flux.Good performance of the flux should have the following characteristics: Soldering effect is good or bad, in addition to the quality of the welding process, components and PCBs, the choice of flux is very important. In wave soldering, flux and solder are used separately, while in reflow soldering, flux is used as an important part of solder paste. Flux is an indispensable auxiliary material in the SMT soldering process.
