beginner welder mistakes, secret technique of welding galvanized thin metal 

The old school dudes tell me to drink milk before a full day of welding galvanized. I’m not sure if it works but I’ve never gotten galv poisoning myself and I’ve had my head all up in the smoke at times. Been working with guys who have gotten it and it’s 100% not a joke.

Milk doesn't do shit. Old wives tale. Simply _strip the galv before welding!_ Muriatic Acid dissolves the zinc a treat. So will white vinegar (though you want the stronger crap - 20+% - or you'll be there all night. 1. Cut pipe/conduit/strut to length. 2. Soak portions of pipe to be joined in a PLASTIC OR GLASS container with acid of choice (don't go breathing THESE fumes either, goes without saying). 3. Wait until the fizzing dies down (couple minutes). 4. Pour acid into disposal container. 5. Dunk part formerly bathed in acid into solution of baking soda and water (this neutralizes any remaining acid). 6. Weld. And soon. This strips the part down to BASE STEEL, and it'll start rusting if you wait too long (>30 min or so) You'll get a MUCH better join (no slagged zinc in the joint), no heavy metal burn off, and, every time you're successful (rumor has it, anyway) a shop teacher gets his wings. Dunno about that last one there, but worth a shot. Self-flagellate with safety bleating: goggles, gloves, respirator, blah blah blah. It's acid. You go breathing it, blinking it, or bathing in it, we can prolly do without you in the gene pool.

Also it won't make you sick as hell welding either when the galvanized coating is ground off.

Ткнул-отбил шлак, ткнул-отбил и так пока не заваришь?

@@Dachnik_Slavyan да не надо каждый раз. как на видео - просто паузы по длиньше и направляй электрод больше в толстую часть металла(ребро). пока шлак "красный" он не мешает формировтася шву

нах менять полярность, просто паузы подольше и нормально

@@Aytist-Down Потому что температура дуги на плюсе 3000 градусов, а на минусе всего 2000 . Я смотрю тут одни специалисты...

@@user-sn4dm8mu4w на прямой полярности варится в основном если металл, который нужно варить , толстый. А так все варят на обратной и нормально

Yes

Конечно😮

1 mm rod is not available in some countries. Here in the Philippines usually use 2mm to 2.5 mm because that's the only available in local hardware. We can't fully weld a thin metal with this but we can do a spot welding just for gates and fences. For structures like stairs of course we use thicker metals so that we can fully weld it

Bisa mohon diterangkan cara mem pesokkan besi 0,5mm?

@@silvercat3243 tinggal titik pojok", lalu tengah di palu dipesokan,trs las full, di jamin kuat, kalau sekedar las rata trs digerindra dijamin bakalan patah.

@@rajademit5250 kalau cara lasnya aakah sama dengan yg di video ini atau punya cara lebih baik mas karena saya jadi ragu karena melihat komen anda ttg cara las di video ini. Kalau cara sambung besi hollow saya rasa betul apabila perlu di pesok dulu.

@@silvercat3243 saya udah 12 tahun terjun di bidang pengelasan, pengalaman saya dulu waktu ngelas buat kanopi, pengelasannya seperti di video, ketika di pemasangan kanopi, otomatis kita naik rangka kanopi untuk masang atap spandek, setelah terkena beban manusia sama atap ketika di atas waktu pemasangan, saya lihat rangka ternyata patah bekas pengelasan, Karena kita dulu kalau las itu rata, trs di Gerindra supaya rata permukaannya, kalau di Gerindra akhirnya kan tipis hasil pengelasnya, beda sama yg dipesokan 1mm, setelah pesok, baru dilas penuh, meskipun digerindra rata, hasil lasnya di dalam banyak gK tipis,

Это профильная труба, только зачищенная до блеска для съемки.

Looks like 3/32

Приблизительно 45.

Какие ,блять, ГОСТы на профтрубу и калитки?😂

Mostly 6013, 2mm diameter nikko steel brand.

@@silvercat3243 My E6013 From Lincoln Will Not Weld Galvanized Steel, Not 40, 60, 80, 100 Gets Burned Part Only,,,,Thank You Friend.

@@-mejor-que-nostradamus-6152 that's too bad, we have some issues regarding a certain galvanized metal as well but usually taken care by simply grinding the material surface a bit before welding. More specifically we are commonly use the AWS A5.1 6013 rod with High Titania covering. Hopefully the data could become handy if you should find other electrode brand.

@@silvercat3243 God Bless You....Thank You So Much.

Whenever someone doesn't talk and wags their finger during the video, then I know they don't know what they're doing.

Please tell why this terrible. Im trying to learn stick welding.

Hi Tommy, as per the other poster, please share with us why? I'm also curious to know.

Yeah, tell me why this is terrible? It looked pretty good to me…

If u don't have a proof it means u just a jerk🥴

i agree everytime you made the tapping welding there's many chances you're just covering the slag that will turn into a weld defects it's on the book already, covering a slag without removing it with chippikng hammer will turn into a welding defect

просто маленький опыт сварки.
