Welded assembly tolerances that hold in production
Welded assembly tolerances: the stack of part, fixture and weld shrink, the values a frame can hold, and when a ±0.5 mm callout needs machining instead.

Sheet metal manufacturing guides
The engineering behind stamped, laser-cut, formed, welded and coated parts: tolerances, tooling, coating failures and what a drawing needs before it can be quoted. Written and reviewed inside the Ganesh plants.

How to quote a welded assembly: cost structure
A welded assembly quote is material, cutting, forming, weld time, fixture amortisation, coating, inspection and packing. A worked example showing which line decides the price.
Read
Robotic versus manual welding cost: the crossover
Robotic versus manual welding cost: arc-on time, minutes per metre, fixture hours and the part count where a cell pays back, worked on a 4.2 m frame.
Read
Welding heavy-gauge material handling parts
Welding for heavy-gauge material handling parts: joint prep, pass count, heat input and the fillet size that carries a 10 mm plate without full penetration.
Read
Assembly-ready fabricated metal parts
What assembly-ready actually means in millimetres: clearance stacks, matched pairs, coating growth and the packing sequence a build line can use.
Read
Seven-tank pretreatment: what each stage prevents
The seven-tank pretreatment process explained by the defect each stage prevents, with film thickness, adhesion and cure values a coating drawing should carry.
Read
Why powder coating fails on outdoor enclosures
Blisters, edge rust and chalky panels are pretreatment and cure failures, not powder failures. The five modes and the callouts that prevent them.
Read
Degreasing before powder coating
Why degreasing decides powder adhesion: what has to come off, how a seven-tank line works, rinse conductivity, film build, cure and the failures it prevents.
Read
Phosphating and conversion coatings for steel
Phosphating and conversion coatings for steel: iron versus zinc phosphate, coating weight in g/m², rinse quality and the checks that predict powder coating failure.

Go from reading to checking
The guides follow the same questions as the free tools. Size a press, check a bend, estimate a cut part or build the RFQ pack.
