For Australian fabricators, food-equipment manufacturers, marine engineers, and chemical-process equipment makers, the right stainless rod matched to the parent material is essential. Wrong rod selection produces welds that corrode in service, defeating the purpose of the stainless construction. AIMS Industrial supplies stainless steel welding rods from Bossweld and approved welding consumable brands.\u003c\/p\u003e\n\n\u003ch3\u003eThe stainless rod grades we stock\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e308L\u003c\/strong\u003e — for welding 304 and 304L stainless steel; the most common general-purpose stainless rod\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e309L\u003c\/strong\u003e — for welding dissimilar metals (carbon steel to stainless), and 309 stainless parent material\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e316L\u003c\/strong\u003e — for welding 316 and 316L stainless steel; marine-grade and chemical-resistant applications\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e312\u003c\/strong\u003e — high-chromium rod for difficult-to-weld stainless and dissimilar applications\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e347\u003c\/strong\u003e — for stabilised stainless grades and high-temperature applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe \"L\" in 308L, 316L, etc.\u003c\/h3\u003e\n\u003cp\u003eThe \"L\" indicates low carbon content. Standard 308 and 316 grades have higher carbon, which can lead to chromium carbide precipitation at grain boundaries during welding (sensitisation). Sensitised stainless is susceptible to intergranular corrosion in service. Low-carbon \"L\" grades resist sensitisation, making them the preferred choice for welded stainless components — particularly in chemical and food-grade applications.\u003c\/p\u003e\n\n\u003ch3\u003eStick electrodes versus TIG rods\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eStick (covered) electrodes\u003c\/strong\u003e — coated rods for SMAW (manual metal arc) welding; the everyday choice for repair and field welding\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTIG (bare) rods\u003c\/strong\u003e — uncoated rods for GTAW (TIG) welding; produce the cleanest welds for food-grade and high-finish work\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMIG wire (welding wire)\u003c\/strong\u003e — see \u003ca href=\"\/collections\/mig-consumables\"\u003eMIG consumables\u003c\/a\u003e for stainless MIG wire\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhere each grade earns its place\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e308L\u003c\/strong\u003e — general 304 stainless fabrication, indoor food equipment, light chemical exposure\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e316L\u003c\/strong\u003e — marine fabrication, food and beverage processing, chemical equipment, pharmaceutical manufacturing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e309L\u003c\/strong\u003e — repair welds bridging stainless and carbon steel, mismatched alloy joining\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e312\u003c\/strong\u003e — repair welds on unknown stainless grades, difficult-to-weld stainless, hardfacing transitions\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWelding stainless — practical notes\u003c\/h3\u003e\n\u003cp\u003eStainless steel welding has specific requirements that differ from carbon steel work:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eLower heat input\u003c\/strong\u003e — stainless retains heat and distorts more than carbon steel; use lower amperage where possible\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInter-pass temperature control\u003c\/strong\u003e — keep parent metal cooled between passes (typically below 150°C)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBack-purging\u003c\/strong\u003e — the back side of the weld must be shielded with argon during welding to prevent oxidation\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePost-weld passivation\u003c\/strong\u003e — pickling or passivation restores the corrosion-resistant chrome oxide layer that welding disrupts (see our \u003ca href=\"\/collections\/pelox\"\u003ePelox\u003c\/a\u003e range)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eBrands stocked at AIMS\u003c\/h3\u003e\n\u003cp\u003eBossweld covers the everyday stainless welding consumable range — Australian-supplied and matched to the welding equipment commonly running in Australian workshops.
