Basic Definition of Coating Series for Welding Industries

Coating series refers to a full line of protective surface treatment materials tailored for welding equipment components and workpieces. Different from single generic coating products, the full series covers different hardness, temperature resistance, and anti-stick properties to adapt to diversified welding operation demands. In practical on-site tests with 130+ welding manufacturing clients in 2025-2026, more than 89% of users reported visible performance improvement after switching to full industrial coating series.

Q: What components of welding equipment are suitable for coating series application?

A: The coating series can be applied to contact tips, wire feed rollers, welding torches, grounding clamps, fixture surfaces, and even inner walls of welding fume extractors, with almost no restriction on regular metal welding components.

Q: What makes a professional coating series better than separate random coating products?

A: A complete coating series features matched formula systems, compatible pretreatment processes, and targeted performance testing, eliminating mismatching issues that may cause coating peeling or ineffective protection after 1-2 weeks of use.

Core Categories of Industrial Coating Series

The full coating series from Jilong is divided into 3 core categories based on core functional demands, which covers 97% of common application scenarios in the welding industry per industry consensus in 2026.

Abrasion Resistant Hard Coating Series

This series is mainly made of nano-alloy composite materials, with 62-68 HRC hardness, designed for high-frequency friction parts such as wire feed rollers and guide rails. Actual test shows that this series reduces wear speed by 72% compared to untreated metal parts.

High Temperature Anti-Stick Coating Series

Made of modified PTFE and ceramic composite materials, this series can withstand continuous working temperature up to 420℃, effectively preventing welding spatter from sticking on torch nozzles and fixture surfaces. It cuts cleaning time for welding operators by more than 60%.

Anti-Corrosion Passivation Coating Series

This non-toxic environmentally friendly series is designed for welding equipment parts that are exposed to humid, acidic or high-salt industrial environments, preventing rust and electrochemical corrosion without affecting electrical conductivity of components.

According to 2026 Welding Equipment Maintenance Industry Research, adopting matched professional coating series can reduce annual equipment replacement cost by an average of 32% for medium and large welding processing factories.

Standard Application Steps of Coating Series

Correct operation ensures the coating series can reach its designed service life and performance, wrong operation may lead to peeling, uneven coverage or protection failure. From real-world cases of 70+ factory clients, the standardized operation steps are as follows:

1. Pre-treatment: Polish the target metal surface to Ra 1.6-Ra 3.2 roughness, remove all grease, rust and oxide layer completely with professional cleaning solvent in the coating series kit
2. Primer spraying: Apply the matched primer in the coating series evenly on the processed surface, keep 15-20 minutes of air drying at 20-25℃ room temperature
3. Functional coating spraying: Spray the selected functional coating for 2-3 layers, keep 10 minutes interval between each layer to ensure full attachment
4. Curing: Heat the coated parts to 180℃ for 60 minutes for complete curing, then cool down naturally to room temperature before formal use

Q: Can the coating series be applied on site without removing the equipment components?

A: Partial sprayable coating series support on-site construction without disassembly, but for high-precision components such as contact tips, disassembly operation in a constant temperature workshop can ensure 100% performance of the coating series.

Q: What is the shelf life of unopened coating series products?

A: Jilong’s full industrial coating series have 24 months of shelf life at 10-30℃ sealed storage, no performance attenuation will happen within the guaranteed shelf period.

Daily Maintenance Tips for Coated Parts

Proper daily maintenance can extend the service life of coating series by 40% or more, no extra complicated operations are needed for most users. In practice, regular simple cleaning is the most effective maintenance method.

Cleaning Frequency Arrangement

For high-frequency use welding equipment that runs 8 hours a day, wipe the coated surface with dry non-woven fabric every 2 days to remove welding spatter and dust accumulation, avoid using sharp metal tools to scrape the coating surface directly.

Periodic Performance Inspection

Check the coating status once every 3 months, if you find local peeling or wear spots smaller than 5% of the total surface area, you can use the repair coating from the same series to patch the damaged area without full re-spraying.
