Hello everyone.
The content on welding distortion and shrinkage is so extensive.
In the previous time, we introduced the content on the effect of welding distortion on angle.
If welding distortion affects angle, welding shrinkage affects length.
In today's video, I will briefly introduce how much welding shrinkage occurs when welding pipes.
When welding pipes, a gap is created between the pipes.
As that gap is filled, welding shrinkage occurs.
And depending on how you weld, the welding shrinkage length varies greatly.
So what happens if you weld a pipe without a gap?
Today, I have included the easiest content to calculate on welding shrinkage in the video.
Welding shrinkage is greatly affected by the size of the gap, the number of welding layers, the amount of heat input, the size and thickness of the pipe, etc.
I will introduce such content later.
Thank you for watching and have a nice week.

여러분 안녕하세요.
용접 왜곡과 수축에 대한 내용은 너무나도 광범위합니다.
이전 시간에는 용접 왜곡이 각도에 미치는 영향에 대한 내용들을 소개시켜 드렸습니다.
용접 왜곡이 각도에 영향을 준다면 용접 수축은 길이에 영향을 줍니다.
오늘 영상에서는 파이프를 용접 할때 용접 수축이 얼마나 생기는지 간단하게 소개시켜드립니다.
파이프를 용접 할때 파이프 사이에 틈새를 만듭니다.
그 틈새가 채워지면서 용접 수축이 발생합니다.
그리고 어떻게 용접하는가에 따라서 용접 수축 길이는 많이 달라집니다.
그럼 갭이 없는 파이프를 용접하면 어떻게 될까요?
오늘은 용접 수축에 대한 가장 계산하기 쉬운 내용을 영상에 담았습니다.
용접 수축은 갭의 크기, 용접 층수, 입열량, 파이프의 크기와 두께 등에도 많은 영향을 받습니다.
그런것들에 대한 내용들도 차후에 소개시켜드리도록 하겠습니다.
시청해주셔서 감사합니다 그리고 즐거운 한주 보내세요.
용접기 및 주변기기에 대한 내용은 제조사에 문의 하시면 더 정확한 답변을 얻으실수 있습니다.

truly a class act, best welding videos on youtube!
Maquina total siempre me deja con la boca abierta 😮 asombroso como dejas la soldadura tanto por su parte a la vista como la que no, y como mantienes la misma linea durante toda la soldadura, no es más fina ni mas ancha por ninguna parte, tus manos tienen inteligencia artificial
Thank you very much!!! Just super example of high quality work! I will be trying to repeat this!
Very well explained, thank you !! 👍👍👍
EXCELENTE VIDEO¡¡
He is fantástic ❤
Very good
Super.Merci
It's a beautiful welder very nice❤
Hi you'r the best welder good job i love so much ❤
Love your videos man! I awlays find myself back to your page for tips
what is name of that marking tool he using on beginning ? i need such a thing please
Zo doen wij het ook. Heb je al eens argon waterstof gebruikt? Dit maakt dat je boog veel nauwer wordt, ook je naald stomper slijpen zorgt voor een vernauwing. Zo leg je maar 1 pas en heb je nog minder krimp. Moet je eens proberen. Keep up the good work!!!!
what measure device is that please? on beginning of video
Добрый вечер, а какой у вас сворочный аппарат?
Wow. Before see it, I believed it will expand, not shrink!
Stainless definitely contracts when it cools. For sure 👌
👍👍👍

So, if I weld without a gap I will avoid this 1 mm shrinkage? Thank you for the video
no . as he showed there is a 1% shrinkage. to adjust you need to do many welds and test your results and then oversize your work pieces so that after welding they are the correct length. This is important for high tolerance work. Most people will not have this problem but even Auto Body repairs must be performed within 2mm for correct OEM alignment specifications. Most shops perform sloppy work but that is why there are suspension alignment adjustments. If the situation was extremely important and no adjustment is possible then you would have to test your shrinkage on scrap material and make the parts larger before welding.
Engineering should have fit up as such that the shrinkage leaves you with the desired dimensions.
1 mm menos 😳
Stainless Steel with NO bevel just as good. Flat on Flate only.
Большинство сварщиков не знают об этом «секрете» по причине того, что не варят космические корабли и атомные реакторы сидя в кресле у вращающего устройства с поддувом. Когда в сварной конструкции десятки швов, нет времени на рефлексии по соединениям встык, общая геометрия и подыгрывается выставляемыми зазорами. Для идеальной же размерности существуют кондуктора, прочая производственная оснастка и сварочные роботы, которые проходят швы в идеальном соответствии техпроцессу.
