Got a welding project to do? Need help with tig welding? Don’t worry. We’ve got some tips on how to tig weld that will save you and your welding project from disaster.
If this is your first welding project, it’s best if you get a little background information on welding first.
Welding, unlike soldering and brazing – two things that are usually mistaken to involve a similar process as welding, uses coalescence to join metals or thermoplastics.
This is done through melting the work pieces and adding another material to create a weld puddle which, when cooled, becomes a strong joint and produces the weld. So a weld, in case you’re still wondering, is simply a joint formed by welding.
To produce a good weld, first you need to make an arc. With this arc, create a weld puddle and put fill metal on it and push it along the weld joint. Finish the arc. Let the puddle cool and protect it by leaving the torch over it.
In Tig welding, it’s also important to establish a good electrical contact between the tungsten and collet. This way, current transfer and weld quality can be improved.
Practice good maintenance for your welding tools by checking them regularly for worn parts and keeping your tig torch components tightened always. You should also clean your weld joint and the filler metal by removing oil, grease, and dirt, as these elements may cause arc instability or dirty welds.
There are many books and courses that provides more tips for tig welding. Welding is both an art and a science but to achieve a perfect tig weld, you have to practice it often to get the hang of it.

Help answer the question about welding
What kind of welder should I buy for welding angle iron?Im planning on welding trailer frames, i would like to be able to weld thicker metal later, i was looking at ark and mig welders, and i wanted to know how many amps and volts to get. I will be welding 1/8" to 3/16" angle iron i think, i don't really know yet.

nice weld
the metal isnt dirty enough to affect it. I certified with metal that looked like that
Dont hold….!!!!
I would like to see that weld cut open and sent to a lab for testing. HE DID NOT EVEN CLEAN THE METAL. Dirty welds have poor penetrations and are set up to fail. People, if you are too lazy to clean the metal, don’t weld.
Certainly its possible and regularly done. One of the acceptable filler rods for 4130 cromo is mild steel. You can join 4130 to mild steel without difficulty provided you treat the 4130 part properly-425F preheat and postheat to make sure it doesnt crack. eutectic makes a rod called tigtectic 66 AKA "copycat"rod which could also be used.
One thing you shouldnt do it stick weld or mig weld 4130
18v with 260 wire… I think you should use less wire, more like 190-210. But that’s just me. Weld would look flatter. Have a nice d@y! =)
very nice hand still
Have you guys seen “You Can’t Weld This!”? It’s pretty funny… The guys over at WeldingMart com had it made! Do a youtube search for it
making a triangle is a good technique
Hahaha I work at a Sawmill If the welders where I work cleaned all the metal before they welded they wouldnt be welding very much! I see them blast the metal quikly with a torch and then weld away!
