Tigging Stainless Shafts – Welding and Straightening

Jody Collier — Thu, 13 Jun 2013 14:47:22 +0000

5 stainless steel shafts got gouged on the CNC lathe. Sometimes you weld 2 pieces of metal together, but sometimes welding means putting back metal that was miscut, worn, misdrilled, dented, or whatever. Most of the repairs were easy… just time consuming… but one of them required a dial indicator and some good ole dry washing and speed cooling with an air nozzle. For a minute, I was worried. But in the end the shaft was plenty straight enough for final machining. Also, in case you missed it – the 2012 YouTube DVD BUNDLE is now available! Click here!

Tips for Welding Aluminum Butts 2G Horizontal Position

Jody Collier — Thu, 06 Jun 2013 17:32:23 +0000

2012 Bundle is now available! Click here to check it out! This week’s video is about welding aluminum butt joins in 2G horizontal position. 6061 t6 aluminum 11 ga 1/8″ – .125″ –3mm thick Shielding gas and torch angle are the 2 big things that make the most difference. Too little gas won’t let the cleaning action work… Too much gas makes penetration difficult and makes for a noisy erratic arc. And by the way… That slight angle I put in the joints after tack welding is just for the sake of practice.. To add some rigidity to those small practice plates. What are your thoughts? Enter them into the comments below this post. ( As always, feel free to visit us at our sister site, WeldingTipsAndTricks.com. )

Mig Welding a Jeep Bumper Kit

Jody Collier — Fri, 31 May 2013 19:54:45 +0000

This weekly video is about mig welding a Jeep bumper kit. I found a kit that is inexpensive, easy to make, and very simple… like me. The reason I am welding a Jeep bumper this week is… Apparently, I suck at driving. The bumpers that came on the Jeep when I got it are chrome plated steel tube bumpers and they stick out pretty far. I hate to admit it, but I misjudged how far my bumper sticks out and it nipped the trim on my garage door. Then my son was backing the Jeep out one day and hung the other side. So maybe it’s not just me… Crappy driving must just run in the family. Bottom line is it’s time for a different bumper. From the day I got this Jeep, I figured I would swap out the bumpers with some DIY kits. I am finally getting around to it. Since work is kinda slow, it is a good time for me to weld some bumpers. I really like the idea of DIY welded bumper kits where the metal is supplied pre cut. If you do the math, you can hardly buy the steel and cut it for [...]

One of the things I like about welding is that there is always something new to learn… Always. After working with other welders since 1977 and teaching welders for over 20 years, I have learned a few things about welders and how people learn to weld… We Welders are a different breed. We typically learn by watching and by doing. Not just by reading. When it comes to welding, the best learning often happens just by looking over someones shoulder and then trying [...]

TIG Welding Stainless Tubing

Jody Collier — Thu, 16 May 2013 15:16:01 +0000

This week, we weld stainless tubing. After talking about scratch start tig welding a few weeks ago, I thought I’d talk about how to weld stainless tubing…a 6g stanless tube test using the same crude scratch start tig setup. It’s a Lincoln 225 AC buzz box with a diy rectifier hooked up to a tig torch. But with a twist. I made a crude foot switch so that I can stop and maintain shielding gas. It might seem rinky dink, but it really makes a big difference on a scratch start tig rig. Stainless tubing used for food and beverage applications is mostly done with no filler metal. Why is that? One reason is that the main quality issue on food service tubing is the surface of the root pass. Not strength. The ability of the surface of the inside of the tube to resist bacteria growth is the main goal… And that means a root pass free from pits, oxide islands, crevices, etc. A sugared root from no purge is about the worst thing that can happen. The goal is a smooth and silver root pass with no crevices that can grow critters. Periodic bacteria swab tests months and [...]

Arc Force vs. Dig vs. Arc Control

Jody Collier — Sun, 12 May 2013 21:04:17 +0000

What is the arc force setting on new inverter welders? What is Dig? What is arc control on an older Miller syncrowave 250? Guess what? These differently named control knobs are the same thing. No matter what the name, it is a setting that allows you to adjust the arc to a soft smooth arc to a more aggressive digging arc. What arc force setting does when set high is to bump up amperage when you have a really tight arc. My usual advice to anyone having any trouble setting amperage for stick welding is to set the machine just hot enough so that it will not stick the rod when you hold a tight arc. Then… hold a tight arc./em> So, it makes sense that I would be a fan of arc control/dig. In other words, when you are just about to stick the rod (that’s why they call it stick welding… right???), the arc force bumps up the amperage just a bit so that you keep welding. Most operator manuals recommend setting the arc force knob to around 30 or so for 7018 rods. But I like to turn things upside down sometimes. Because I like a tight [...]

Tig Welding 4140 to 1045

Jody Collier — Wed, 01 May 2013 15:44:05 +0000

This weekly video is about Tig Welding 4140 Steel to 1045 Steel. The customer supplied a drawing to modify 20 snap ring pliers and weld some jaws on the end that were machined out of 4140. Inconel 82 tig rod was used because I have had a lot of success with inconel 82 in repairing tool steel injection molds. 312 stainless would have been my first choice, but I had the inconel 82 rod in storage and in the right diameter… so I used about 3 rods to complete all 20 parts. What rod would you have used? ( As always, feel free to visit us at our sister site, WeldingTipsAndTricks.com. )

Here Comes the Mig Welder Boom – Part 2

Jody Collier — Wed, 24 Apr 2013 20:47:37 +0000

This is Part 2 of building a boom arm for a mig welder. A millermatic 250 mig welder to be exact. The aim is to remove the wire feeder components from the welder and install them in a separate wire feeder cabinet that will hang on the end of the boom. This is a prototype so I will make changes along the way. The hinge is kinda small and the base plate might be too light… But all these things will come to light when it’s done and in use. There are lots of small shop owners out there who could benefit from a wire feeder on a boom arm. Maybe you’re one of them. It is a much cheaper way to go than buying a separate wire feeder unit. I welcome any suggestions so lets hear them… ( As always, feel free to visit us at our sister site, WeldingTipsAndTricks.com. )

Old School Scratch Start Tig… With a Twist.

Jody Collier — Thu, 18 Apr 2013 16:26:30 +0000

This weekly video is about a simple scratch start tig setup along with a diy foot switch. The rectifier seems to put out a very wavy DC current. I kinda like it. It’s like high speed pulse. What kind of stuff have you welded with a simple scratch start rig? ( As always, feel free to visit us at our sister site, WeldingTipsAndTricks.com. )
