Weldweft: Welding Log

Weldweft is the notebook we wished we had on the cart: one card per setup, with the machine, the process, the joint, the wire or rod, the gas mix and the exact settings that made it run right. The next time that 3/16 angle job comes back, you pull the card, set 19.5 volts and 320 ipm, open the C25 to 25 CFH, and you are back where you left off. Every setup card holds the numbers that matter: volts, amps, wire speed, travel speed, polarity, preheat and interpass limits, plus the filler class and diameter and which bottle was on the machine. As you type, the heat input works itself out in kJ/in and kJ/mm, with the arc-efficiency factor for MIG, TIG, stick or flux-core applied so you can see the effective figure too. Wire processes also get a deposition estimate and a rule-of-thumb amperage check from the wire speed and diameter. We built the coupon gallery so the evidence lives next to…
