Controlling weld distortion in frames
Why welded frames move, the sequence and fixture rules that hold the diagonal, and the distortion allowance to put on the drawing before quotation.

Welded sheet metal enclosures: rack tolerance and finish
Welded sheet metal enclosures live or die on rail position, frame squareness and earthing continuity. The numbers to specify, and where welding fits.

Welded genset base frames: flatness, skid and lift points
Welded genset base frames fail on flatness, isolator hole position and lift points, not weld strength. Here are the numbers to put on the drawing.

Welded elevator counterweight frames
How welded elevator counterweight frames are built and inspected: datum strategy, weld sequence, diagonal control, coating and the drawing callouts that matter.

Forklift overhead guard fabrication: ISO 6055 limits
Forklift overhead guard fabrication to ISO 6055 dimensions: roof opening limits, clearances, weld sequence, deflection control and coating.

Welding aluminium sheet assemblies
Welding aluminium sheet assemblies: filler choice, cleaning window, current range and the heat-affected zone strength that decides the joint design.
Read
Spot welding for panels and enclosures
Spot welding for panels and enclosures: nugget size, edge distance, spot pitch and electrode life, with the numbers that decide whether a panel holds.
Read
Welding inspection and traceability for sheet metal
Welding inspection and traceability: which quality level to call out, what to measure at each stage, and how the record survives coating and dispatch.

How fixtures improve repeatability in welded assemblies
A fixture cuts the spread on a 900 mm welded frame from about ±3.0 mm to ±0.7 mm. Where that variation comes from, what the fixture must locate on, and how to prove it.

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.
