Small pipe 15A (Stainless steel) sch10 Pipe welding video! 

nice to meet you. welder jin.
The theme of this video is 15A (Stainless steel) sch10
Pipe welding.
Place the dottech using nitrogen purging.
If you use the Engle as a support, you can easily fit-up.
Fit-up is finished.
Solvent 2.0mm
Electrode 2.4mm
ROOT GAP 2.5 ~ 3.0mm
I put it at 6 and 12 at spot welding.
Shrink and deform well during welding. You have to work carefully.
We used collet mesh body for drawing welding.
Electrode length is not critical.
Easy setting in the protective gas area.
electric current. Welder value is set to 45.
We will proceed welding carefully as the pipe size is small.
Root pass welding in progress ...
It can be seen that it is supported on the pipe with the exception of thumb and index finger. Prevents camera shake and makes control easier.
Don't be scared It's just a small size.
The welding method is the same.
Law of Gravity !!! Remember the concept. Will help.
Let's observe again.
At 6 o'clock, we're going to
As we approach 12 o'clock, the position of the solubilizer is Out side.
If you break during welding, don't be afraid to start again 3mm before creating a smooth back bead.
You can increase your proficiency through practice of disconnecting and connecting.
Whatever the process, there are consequences.
Nothing will happen by itself ...
The argon gas protects the pipe well so the surface is not discolored and shiny.
The better the argon gas protects the pipe, the better the weldability.
Let's look at the welding process from the first person perspective ...
Final welding.
I'll observe it from a different angle.
This completes the final welding.
I'm going to make a cut ... should I check for sure ???
Grinders are dangerous. Please use carefully.
Nothing is more important than safety.
Always work with safety in mind. exactly!!!
Let's look at this side bead ??
good. share. subscribe.
It will motivate you to create new images.
