304 Stainless Steel Storage Tank

Appropriate Welding Methods

Argon arc welding is mainly applied for tank root welding, while manual arc welding fills outer welds. Argon protection on weld inner surfaces stops oxidation, protecting the inherent corrosion resistance of 304 stainless steel. Operators limit welding heat input to lower thermal deformation and intergranular corrosion.

Post-Weld Inspection & Treatment

All welding lines are polished evenly to eliminate welding slag and burrs. Surface cracks and pores are checked visually. Key welding areas adopt penetrant inspection to find invisible tiny defects. Welding residues are fully cleared after inspection.

Practical Value

Standard welding keeps tanks airtight and durable. Well-controlled welding procedures make the tank fit for long-term storage of food, water and common chemical materials with stable anti-rust performance.
