De,
Most of what I saw of the machine . . . I suspect
brazing might be a better idea than welding.
Welding of thin metals (like the drum or the tank)
tends to burn a hole through it.
Gasification: (which seems to be the source of the fuel.)
From Wikipedia:
Gasification is a process that converts organic or fossil fuel based carbonaceous materials into carbon monoxide, hydrogen and carbon dioxide. This is achieved by reacting the material at high temperatures (>700 °C), without combustion, with a controlled amount of oxygen and/or steam. The resulting gas mixture is called syngas (from synthesis gas or synthetic gas) or producer gas and is itself a fuel.

Brazing is a metal-joining process in which two or more metal items are joined together by melting and flowing a filler metal into the joint, the filler metal having a lower melting point than the adjoining metal.

What is the difference between brazing and soldering?
Brazing - The AWS defines brazing as a group of joining processes that produce coalescence of materials by heating them to the brazing temperature and by using a filler metal (solder) having a liquidus above 840°F (450°C), and below the solidus of the base metals.
Soldering - Soldering has the same definition as brazing except for the fact that the filler metal used has a liquidus below 840°F (450°C) and below the solidus of the base metals.

Zim: This site seems to have a fair amount of general
information on brazing. Might be worth the read.
