01Fabricated or machined steel parts rusting before painting or dispatchFlash rust on fabricated or machined parts waiting for paint, welding or dispatch? Why it happens and how a temporary rust-preventive film helps.
02Scratches, cut edges or damaged galvanising on railings, pipes and structuresRust starting at scratches or cut ends on GI railings, pipes or scaffolding? Why galvanising fails there and how to touch it up with zinc-rich coatings.
03Heat-treatment fixtures, jigs and furnace parts oxidising or scalingScale building up on heat-treatment fixtures and jigs over thermal cycles? Why it happens and how ceramic protective coatings are used on fixtures.
04Robotic welding torch nozzles clogging with spatter and slagRobot stopping for torch cleaning, nozzle bridging or lost gas coverage? Why it happens and how a dry ceramic anti-spatter film helps on automated lines.
05Rust at weld seams on galvanised steel after weldingBurnt zinc and rust around weld beads on GI? Why welding strips the galvanising and how to touch up weld seams with a zinc-rich spray or brush-on paint.
06Spatter sticking to the MIG/CO2 torch nozzle and contact tipSpatter balls welded to the nozzle and tip, blocked gas flow, frequent nozzle changes? Causes and how to choose an anti-spatter spray for your welding job.
07Need a zinc-rich primer before topcoat on steel fabricationTopcoat failing or rust creeping under paint on steel? Why a zinc-rich base layer helps, how to prepare the surface, and what to check about your topcoat.
