Robotic Welding Crater Fill: 7 Steps to Prevent End Craters
A practical guide to diagnosing and programming robotic crater fill using coordinated wire feed, voltage or arc length, ramp time, endpoint motion, burnback and gas post-flow.
Robotic Welding Seam Misalignment: 6 Causes and Fixes
A practical diagnostic sequence for robotic welds that run off the joint even when the programmed teach points appear correct.
Welding Undercut: 5 Causes, Prevention, and Repair
Learn the main welding undercut causes, how to prevent the defect in manual and robotic welding, and how to inspect and repair it correctly.
How Do You Adjust MIG Welding Current and Voltage? Remember: Current Controls Penetration, Voltage Controls Bead Width
MIG welding current and voltage settings confuse many new welders because one small turn on the machine can change penetration, spatter, bead shape, and arc sound. If the current is too low, the weld may not fuse. If the voltage is wrong, the puddle may pile up or spread too […]
