Bend Test Quality Check
Coming Soon
How to perform and interpret bend tests on friction welded joints. Sample preparation, mandrel sizing per joint diameter, acceptance criteria from ISO 15620 and AWS C6.1, common failure modes and what they tell you about the weld.
Bend Test Quality Qualification ISO 15620
Reading Weld Graphs
Coming Soon
How to interpret pressure-displacement-time traces from friction welding machines. What a healthy graph looks like, what spikes and dips mean, how to spot a developing problem before it becomes a reject.
Weld Graph Diagnostics Process Monitoring
Friction Welding Tech Tips
Coming Soon
Working notes from the shop floor. Chuck concentricity, face preparation, dealing with dissimilar materials, common operator mistakes, and the little things that separate a clean weld from a struggle.

How to Grease a Bearing Properly
Coming Soon
The right amount, the right grease, the right interval. Why over-greasing kills more bearings than under-greasing, how to calculate refresh volume, and what to do when there's no specification to follow.

Reforming Stored VFD Capacitors
On VFD Page
Electrolytic DC-bus capacitors degrade in long-term storage. Energising at full voltage risks a destructive failure. The reforming procedure restores the oxide layer gradually using a variac or dedicated tool. Read the VFD page for full guidance, or get in touch for a reforming service.
