A place for anything to do with Welding.Post your welds, ask questions and discuss sticking metals together.IDK I just want a place to talk about welding.Thread Theme: Wacky WeavesPrevious:https://warosu.org/diy/thread/2932874Previous before previous:https://warosu.org/diy/thread/2894379
Tell me why I shouldn't just do straight lineThey all look the same
>>2973045because each one has different applicationshttps://www.arccaptain.com/es/blogs/article/welding-weave-patterns
>>2973045The weaves are slightly wider. >Tell me why I should use one weave over the other.There is no why. It doesn't matter.
>>2973048>There is no why. It doesn't matter.you'd fail a steamfitter job for sure
>>2973050So I'm told.
Haven't welded in about 2,5 years now. Ever since I moved and got an office job.I'd like to buy a TIG but I know I won't use it often. Not enough projects around the house :(
>>2973045Avoid square weave technique unless you have a reason to do it.The bead width variation isn't worth it. Inspectors judge bead width, based on most narrow measurement.Square weave pattern will commonly fail inspection if you ever push the weld pool too far. Not worth it.Stick it consistent bead width, if that means a different weave technique, so be it.Weld superiority isn't subjective.You use the correct motion for the application, and you achieve a perfect bead output.No one cares how you actually maneuver your electrode tip, except the inspector when they find bead inconsistency.Equal fluid movement of the weld pool at consistent bead width is the way. Anything else is the dark side.
>>2973196Not to say it's bad, it's just that other motions can make up for a mistake like slightly pushing your pool too far.If you do it with square weave, you're going to become a grinder instead of a welder.So, use the other motions, as they will forgive/cover up your mistake of inconsistent travel speed.Square weave will not forgive that, as your pool will be beyond the toe of your last wave crest. Missing overlap within your own bead line is CRAZY and isn't even a possibility with most motions.Square weave can do that, if you think about it, you are missing overlap, on the same bead you are making. From an efficient professional welding standard, this is bumfuck crazy and makes a mother fucker wonder, who even invented square weave? It's shit, unless you have to make that motion for a riveted/equally spaced bolted edge, there's almost NO REASON to ever square weave.
>>2973061Why not just get a simple cheapo stick welder?No gas canister. You can buy rods at local hardware stores. If you need a weld to look pretty, just grab some 7018's. If you need wire level/precision work, use a soldering iron kit.SMAW stick welding is good enough for 99% of home level work.Can be done for much cheaper, low cost stick unit, cost of rods, no gas to worry about. For home project/sporadic use, you really can't go wrong with stick.(No rod oven though, better stick to the resilient stuff, men and children are separated by whether or not they are comfortable with 60x0 rods.)
I want to make a test sample for dye penetration. I was thinking doing a weld bead that cracks for sure (preferably invisible that only comes up with dye), grind and polish to flat.What would be an "ideal" way to do this? What filler what settings would work?
>>2973061>>2973204just get a stick/mig machine with flux core wirethen you can dual shield if you want later
>>2973207Welding cast iron with mild steel filler rod will crack for sure.
>>2972986The third one is best right?
>>2973204if you can mig why the fuck would you stick?
>>2975498I prefer stick welding over mig for lots of the stuff I weld. You don't have to clean stuff up as carefully because 6010 or 6011 will burn right in anyhow, get better weld penetration on thicker material, and don't have to worry about your shielding gas blowing away.
>>2975525>don't have to clean>will burn right in anyhow>get better weld penetration on thicker material>don't have to worry about your shielding gas blowing away haha innershield at 300a go brrrrrr
>>2973045when you go to test for aws certs they recommend you use a straight line. you should use it and produces strong welds
>>2975559>haha innershield at 300a go brrrrrrI've tried flux core exactly once.... Not my cup of tea. I do have a small spool that came with a welder and another 10 or 11 lb spool that I should probably use up sometime.
Picrel: worth it or not, for beginner hobbist? Just read a little ftom link here >>2973047; what can it do, metals/thickness wise, and what can't it?
>use 6014 rods>hate it and they suck ass>get 7014 rods>works great
>>2975787>what can it do120A, that would be 6mm 1/4" absolute maximum>what can't itgas. that machine is gasless only and thin wire too, which for a lot of applications is pure dog shit. I worked in a welding supply shop for 10 years of my life. I realize people want to spend as close to $0 as possible and get a machine that can do everything. I would not recommend a machine like pic related unless all you want to do is 3mm plate on trailers and fencing.
>>2975833Yeah, just browsed yt and there's s lot of videos about it and mostly praising it (ex : https://m.youtube.com/watch?v=LariCNWmY1w(, hence why I was wondering.
>>2975836Those power electronic machines usually fail when one or more of the power transistor fail. If it happens, figure out which ones failed with a multimeter then order replacements. Cost me $20 to fix a $300 machine.
muricans cannot fathom the 7018 open root
