Will you be doing the RT test?

Is anyone familiar with the radiographic inspection of the socket welds? Could anyone give me some details about it? Thank you Hello and welcome to the forum Will this be welded to a code? If so you can only ask what that particular code says about this. For instance after a brief Google search of ...

I'm not sure if this is some super top secret thing, but hoe does Jody get these great behind the lens video that you can clearly see the arc, weld and surrounding metal? I would line to know what kind of camera, app, exposure settings, filter/lens etc to use.... I saw a video on HDR filming but I ...

Welcome to the forums Tim

I buy materials for the shop I work at, if you need a drop piece you're going to pay more, but that's true of any consumer item. I've buy from onlinemetals, they have a warehouse in Orlando so its delivered to me the next day. There's also SpeedyMetals.com, and I also have a Alro Metals Plus shop ab...

When testing I always hot pass but when welding on the job rarely did we hot pass - just go to stick. Every long lonesome now and then you will blow through the root while stick welding. Not knowing what tubes will be selected for Xray you need to do something about the blow through. What I do when...

I've done a lot of fitting up down thru the years. We were putting together a tank bottom a few years ago and we had a "golden arm" on the job and welding was all he would do. This guy started out wanting someone to run his welding leads for him cause he thought that was a helpers job. We...

Hello out there, Started a new job in jan this year as a painter. The company found out I had previously been welding etc at work and at home so asked me to help out in the metalworking side of things during a busy period. I can mig weld and tig weld, but run into a little problem with how they do ...

I'm getting better at striking an arc, but I'm running out of metal that I can experiment on. Now I'm trying to find sources of metal other than my handy Ace store or the big box stores. The lws suppliers nearby seem to only offer gas, machines, and consumables. Folks in other areas, how do you fin...

I have never refused a weld. I will find a way. But a three-mirror weld will take the cake!

Is that anything like a three dog night?!

Well done, I thought your words came out quite well. Sorry for your loss

Anyone have anything to say about these courses? http://awo.aws.org/seminars/metallurgy/ The metallurgy one is what I'm mostly interested in, but if anyone has info on the other courses, I'm sure we would all be interested in hearing your experience. Yeah I'd like to know the same, would like to ta...

big gear head wrote:Would 4130 wire make it better or worse?

Well, 4130 matches the base metal and would need PWHT (post weld heat treatment) so in your situation it would be worse

From Welding Design website "The heat from welding makes the base material expand during heating and contract when cooling. This creates residual tensile stresses around the weld that can cause cracking or shorten the life of the part. Typically, AISI 4130, 4140, and 4340 require a stress relie...

OK I have made a lot of small parts from 4130....mostly .040 welded to .060 formed parts. I have metal sheet stored in the building with light oil sprayed on it and wiped down. After I cut my parts on the bandsaw and get them shaped with flap wheel and deburred I usually soak them in acetone for a ...

it can become very hard to work with after welding that's one of the reasons the guys like to use the SS rod i found this web page saying use h11 rod so i thought i would ask and see if anyone had tried it http://www.simplytoolsteel.com/H-13-tool-steel-data-sheet.html or if they had tried anything ...

Hi all hope you can help me with this I build and fix plastic injection moulds for an automotive supplier We have a mould that is made out of Thyssen Thyrotherm 2344 H13 steel The guys I work with have been welding this tool over the years using 309 and 316 SS rod I don't agree with doing that and ...

Thanks
