In addition to the very good points above, please keep in mind that the cleanliness of the base and filler material is also critical. Make sure you degrease both with alcohol, acetone etc.
You also need to be aware that in a small fillet weld like that there is a lot of dilution with the base...
The 410NiMo has a similar composition with the 410 filler wire, except for the much higher Ni content (>4%) which provides a less crack sensitive weld deposit. The addition of four percent Ni has several metallurgical effects:
- Decreases the possibility of delta ferrite formation
- Lowers the...
DOES ANYBODY HAVE ANY EXPERIENCE WITH BEAM ALIGNMENT AND FIT-UP TOLERANCES WHEN PLASMA KEYHOLE WELDING SQUARE GROOVE BUTT JOINTS IN 6 MM (0.25") THICK MATERIAL, WITH NO FILLER WIRE ADDITION? ANY RECOMMENDATIONS ON EQUIPMENT SELECTION?
Rule of thumb: Flat diameter = amperage/4000 (for example: 80A/4000=0.020")
Different angles produce different arc shapes and offer different weld penetration capabilities. In general, blunter electrodes that have a larger included angle:
· Last longer
· Have better weld penetration
· Have...
