I used to have a smith torch but i ended up buying an airco.
How to weld sheet metal with a torch.
Problems with welding sheet metal.
Proper technique will come with practice and experience.
The main reason to use a smaller diameter wire is that it takes less heat for melting and hence the metal around the weld is not heated to a very great extent.
Using a thinner wire 0 30 instead of 0 35 will also help.
This takes away some of the stretch.
Oxy fuel welding torches.
The bulge can then be tapped down flat with a hammer and dolly to thicken the metal in that spot.
A common recommended fix is to use oxy acetylene heat to create a localized hot spot that bulges the metal above the mean surface of the panel.
These are all little areas of welding a panel or sheet metal that you have to think about.
This mixture when lit produces a clean burning flame suitable for heating or welding purposes.
If you are burning through the metal you re not moving the torch fast enough and or your welder is set too high.
Propane can do the same thing although it is a much more.
Practice welding on pieces of scrap metal that are close to the same size as the material you will eventually weld.
In order to weld sheet metal or patch panel you have to follow certain rules and use specific techniques.
Practice also on different sized pieces in order to get the idea of how to move the torch and at what angles you can hold it.
It s a great torch.
A filler rod is usually blended into the weld for strength.
A propane torch makes welding safe simple and efficient.
Sheet metal welding techniques.
Gas welding joins metal using the heat of a torch burning both oxygen and a secondary fuel.
For mig welding sheet metal it is often recommended to use an electrode wire of the smallest diameter to prevent burn through and warping.
Move the torch faster and or reduce the amp setting of the welder and the lower the wire speed.
