HOW WE TEST EQUIPMENT

We don't test in controlled laboratories. Every machine, every consumable, every parameter we publish comes from real fabrication shops, real production environments, and real welding conditions.

Real Fabrication

Actual shop conditions

Real Production

Not lab-only tests

Real Parameters

Documented settings

Real Consumables

Production wire & gas

DEFECT LIBRARY

Identify, understand, and prevent welding defects. Each entry includes causes, repair methods, and prevention techniques.

Defect Cause Repair
Porosity Contamination, gas flow issues Grind out, re-weld
Undercut Excessive current, fast travel Fill with additional pass
Overlap Slow travel, excess fill Grind flush
Spatter Voltage too low, gas issues Grind or chip off
Cracks Hydrogen, restraint, rapid cooling Grind out completely, re-weld
Burn Through Excessive heat, thin material Back-weld or patch
Lack of Fusion Low heat, fast travel, poor prep Grind out, re-weld properly
