Re: Finding AWS Test Site
We are a bit outside the 3-4 hour drive time but still in Tennesee. Just the diagonally opposite corner. We are also an AWS Accredited Test Facility but do testing in accordance with the AWS certified Welder program https://www.aws.org/library/doclib/QC7-93.pdf and just in accordance with various...

Re: 1g cwb test angle for root
Do you have any pictures of the "cracks"?
Are they side bends or face/root bends?
If they are root bends, do they run the entire length of the face width?
Are there 2 of them parallel to each other?

Re: Someone smarter than me
You can layout a template by hand without a pipefitter handbook. Drawing to scale is needed and its much slower than "downloading" something.

Re: inverter vs. transformer for stick SMAW etc.
The newer inverter power sources work fine for stick welding. Some may not have the ideal arc for cellulose based electrodes but many are satisfactory now. Nothing beats the control of a generator in my opinion but all make decent welds. I used a miller Maxstar 200 for a few years at my last job, it...

Re: Big Weld Test Coming Up
FCAW can support a pretty good amperage range in all positions. Some people may tend to go on the low side however keep in mind that many wires perform nicely when adjusted to spray vs globular type transfer modes. For vertical this isn't so important however when welding overhead understand that if...

GMAW Side Bend, Open Root, Short Circuit.
The video shows an up close view of a bend test on a practice plate in progress. This was done by one of my students last night.
Nothing fancy. I left the root side un polished since it was flush.

Re: Can I convert Flux Core to Arc/Stick
The type of power supply for GMAW and FCAW is a constant voltage power source. The type needed for SMAW and GTAW is a constant current power source. The response of the machine to variations in arc length would make welding with stick/tig on a CV power source extremely difficult. But hey, give it a ...

Re: Welding AR plate to mild steel

Re: Welding stainless to galvanized
If you are doing this on something that is critical you should be aware the zinc and many other low melting point alloys can cause cracking in stainless steel.
Do your similar thickness stainless to stainless stick welds look good? If yes, remove more of the zinc coating before welding.

Re: capping 4" sch 10 stainless pipe
Now that I see some other pictures, removing the oxide layer from around your weld area can also help with the bead wetting out. Clean em up some if you are looking to improve the appearance.

Re: capping 4" sch 10 stainless pipe
There may be a couple of things that are going on. The contour of the bead seems a bit erratic which could indicate you are struggling with consistent travel speed and controlling the puddle. I would concentrate more on the shape/appearance of that weld more than the "color". Get in a posi...

Re: Weave differences
A weave pattern that allows large areas of the underlying metal to be untouched by the arc can result in areas of non-fusion. Keep em tight. Another consideration is the added heat input from the slower travel speeds however this relates regardless of the pattern used and is more of a concern for we...

Re: 7018 Vertical
Try a very slight manipulation side to side with a distinct pause in each side. The bead does not have to be very wide for this to affect the sagging through the middle. Another option is to start with a smaller electrode. Also note this, if you are welding an material that is in the thinner side, h...

Re: Looking for tips and tricks with welding 8N12

Straight Stringers with very little side to side motion is suggested, Also not that there is a great deal of variation among manufacturers...
