Judging Laser Weld Appearance: What Passes and What Does Not Appearance is the first quality gate a laser weld meets, and the most argued-about one. A seam can look imperfect and hold full strength; it can look beautiful and hide a lack of fusion. Without written criteria, acceptance drifts toward ...

Cycle Time and ROI for an Automated Welding Line Almost every welding automation enquiry starts with the same sentence - "we want to reduce labour cost" - and ends, disappointingly often, with a quote that cannot be evaluated because nobody measured the cycle. Automation pays back through arithmetic...

Cold Plate Leak Testing: Pressure Decay vs Helium Detection A liquid cooling cold plate is only as good as its welds, and the test that proves those welds is the leak test. Two methods dominate production floors: pressure decay, which watches for pressure loss inside the sealed plate, and helium ...

Fixtures and Positioners for a Robotic Welding Cell Buyers evaluating a robotic welding cell tend to focus on the robot. In practice the robot is the most predictable element in the cell - the element that decides whether the cell earns its keep is the tooling underneath the part. A fixture that ...

Spot Welding Electrode Dressing and Replacement Cycles The electrode is the cheapest part of a spot welding machine and the first part to ruin your quality. As the copper tip works, its face grows, picks up metal, and quietly changes the resistance of every weld that follows. Lines that struggle ...

Handheld vs Platform vs Robotic Laser Welding: How to Choose Most laser welding questions are not really about the laser. A fiber laser source is a fiber laser source; what separates one machine from another is what holds and moves the beam - and that splits into three forms: a person's hand, a ...

Medium Frequency vs Capacitor Discharge vs AC Spot Welders: How to Choose Three technologies dominate resistance spot welding, and they are not interchangeable: AC machines draw directly from the mains at 50/60 Hz, capacitor discharge (CD) machines store energy and release it in a single fast pulse, ...
