What wire diameter is the Lincoln Lincolnweld LA-90 Submerged Arc SAW Welding Wire available in?

Wire diameter selection is critical for matching deposition rate to base metal thickness. For mild steel MIG wire: .023 in for thin sheet (up to 3/16 in), .030 in for general fabrication, .035 in for the widest range of thicknesses, and .045 in+ for heavy plate. Check the product listing for available diameters of the Lincoln Lincolnweld LA-90 Submerged Arc SAW Welding Wire.

What shielding gas or flux type does the Lincoln Lincolnweld LA-90 Submerged Arc SAW Welding Wire require?

Submerged Arc Welding (SAW) wire is used with a granular flux that covers the arc during welding, providing excellent shielding and slag protection for high-deposition, flat/horizontal position applications. SAW is common in shipbuilding, pressure vessel fabrication, and structural plate welding. This wire must be paired with the correct SAW flux for the application.

What is the deposit strength of the Lincoln Lincolnweld LA-90 Submerged Arc SAW Welding Wire?

Deposit tensile strength for mild steel solid MIG wire (ER70S-x) is approximately 70,000 PSI (483 MPa) minimum. For stainless filler metals, the deposit strength matches the base alloy grade. For flux-core wires, strength and chemistry vary by classification — refer to the AWS classification on the package for the exact mechanical property requirements.

Q: What spool size is the Lincoln Lincolnweld LA-90 Submerged Arc SAW Welding Wire available in?

MIG wire spool sizes range from 2 lb (small hobbyist spools) to 600 lb bulk drums. Most production feeders accept 12 in (33–44 lb) spools. Check your wire feeder's spool capacity before ordering — some compact machines only accept 4 in (10 lb) spools. Using the largest spool that fits your feeder minimizes change-over time.

Q: How should I store the Lincoln Lincolnweld LA-90 Submerged Arc SAW Welding Wire to prevent weld quality issues?

Store MIG wire in a clean, dry location away from humidity. Moisture absorption causes porosity in the weld — mild steel wire is particularly susceptible. If wire has been exposed to moisture, it may show surface rust; lightly rusted wire can sometimes be used but should be wiped before feeding. Flux-core and low-hydrogen electrodes require stricter moisture control than solid wire. Keep spools in their original packaging or sealed containers with desiccant packets when not in use.
