3 Problems With My Oxy Acetylene Welding Torch!
by Anand Charya
I have started making wire sculptures. I join the wires by gas (Oxy-Acetylene) welding process.
In the beginning, I used an Indian made ‘Gas Torch’.
I welded nearly 2000 spots with this torch.
I know about the types of flames.
I know welding is to be done in ‘Neutral Flame’.
I know about the ‘Inner Cone’ of the ‘Neutral Flame’, where the temperature is maximum up to 3000 to 3300 degree Centigrade, and so where the material gets melted.
Now, I have stopped using my old torch, because I found the problem in the valves.
Today, I fitted a China made ‘gas torch’. But with this torch, welding does not happened to be strong and fast.
My work involves Mild steel wire of 2.5 mm. diameter.
Wires are to be weld by touching it’s ends.
What I found while welding:
1. There is a crackling sounds.
2. The Nozzle and it’s tube gets hot.
3. The Cone length is little smaller than the previous torch’s cone length considering the length of only acetylene gas.
Could you please tell me the reasons of these 3 findings?
Thanks with regards
