Welding Rods for Steel

Shandong Weiran Building Materials Co., Ltd. is one of the leading manufacturers and suppliers of welding rods for steel in China. If you're going to wholesale durable welding rods for steel made in China, welcome to get pricelist from our factory. All customized products are with high quality and competitive price.

Welding rods for steel are integrated industrial consumables for shielded metal arc welding (SMAW), precisely pressed with premium metal core wire and functional coating. They integrate electrical conduction, metal deposition, deoxidation, arc shielding and bead forming functions. Manufactured via advanced metallurgical processes with high-purity low-impurity core wire, they are essential core supplies for engineering welding, equipment maintenance, steel fabrication and hardware repair.

• Stable arc with minimal wandering, suitable for all welders: Wide applicable current range and high operating tolerance for seasoned welders' mass production as well as novice repair work to lower operation difficulty greatly.
• Low spatter and easy slag removal for neat weld appearance and labor saving: Optimized deposition formulation cuts spatter drastically and leaves little residual slag on workpiece surface.
• High-temperature and corrosion resistance for diverse harsh conditions: Graded formulations for different applications: carbon steel grades for stable load bearing, stainless steel grades for rust and corrosion resistance, hardfacing grades for impact and abrasion resistance, high-strength grades for high-pressure heavy-load service.
• Compatible with both AC and DC welding power sources: Main grades work with AC and DC welders, matching small household machines, heavy-duty industrial welders and portable inverter welders.
• National standard manufacturing for project acceptance compliance: Fully automatic production ensures even coating thickness, high concentricity free from eccentricity, coating peeling or breakage defects.

Steel structure fabrication, machinery manufacturing and overhaul, stainless steel component welding, cast iron mould restoration, heavy industrial project welding, household and daily maintenance.

Classified by grade to fit various service conditions precisely, these welding rods for steel deliver distinct performances: economical carbon steel type for general steel structure welding; anti-rust anti-corrosion stainless steel type producing clean weld seams; impact and abrasion resistant hardfacing grade.

• Remove rust, grease and oxide scale thoroughly from welding area to keep joint clean and dry, preventing porosity and slag inclusion for improved weld quality.
• Set proper welding current matching rod diameter and plate thickness to avoid burn-through from excessive amperage.
• Maintain steady travel speed and electrode angle during welding; adopt multi-layer multi-pass welding for thick plates to avoid cracking from concentrated residual stress.
• Install wind shielding for open-air welding under windy outdoor conditions.
• Apply post-weld slow cooling insulation, rust removal and anti-corrosion treatment as required; strictly follow qualified welding procedures for high-strength, low-temperature and pressure vessel welds to guarantee long-term service stability.
