replies: text: Torch bodies are usually made of brass while the tips are copper. Both metals are non-sparking, a good thing when working with flammable fuel gasses. The tips don't melt because the gasses don't burn until they are beyond the opening or openings in the tip, thus the tip is mainly heated by radiant energy from the flame. Copper is one of the best heat conducting metals so heat from the flame is quickly drawn away from the tip and some of it is picked up by the gasses flowing through the inside via conduction.

message: An IP editor requested at Wikipedia:Graphic_Lab/Illustration_workshop#Oxygas_welding_station that we change a diagram on this page.  Ivan Akira has produced an improved diagram, distancing the welder's flame from the gas valve.  We would welcome an opinion from a subject expert as to how we can best depict someone welding safely.

message: A person who welds is a weldor. The tools they use to weld with are welders. See the Oxy-acetylene Weldor's Handbook. Same as a sailor is a person on a boat while the boat (if wind driven) is a sailer. You don't call a Navy soldier a sailer so why call a weldor a welder? Bizzybody (talk) 07:26, 4 December 2011 (UTC)
thread_title:  Welders and Weldors 

message: I think it is very necessary when describing the temperature of mixed gas flames (or even single gas flames) to provide a solid reference. This page (and many others dealing with torch welding/brazing/cutting) are severely lacking with references at key points such as this. Hopefully someone with some experience and knowledge of references for this subject matter can chime in and fix this.

thread_title:  Lack of reference 

message: Large chunks of this article are almost identical to http://www.cedengineering.com/upload/Fundamentals%20of%20Gas%20Welding%20and%20Cutting.pdf.  I've worked my way back through the article history a bit, but can't really tell who copied from who.  One specific passage which is identical is:
Welding gas pressures using oxy-acetylene are set in accordance with the manufacturer's recommendations. The welder will modify the speed of welding travel to maintain a uniform bead width. Uniformity is a quality attribute indicating good workmanship. Trained welders are taught to keep the bead the same size at the beginning of the weld as at the end. If the bead gets too wide, the welder increases the speed of welding travel. If the bead gets too narrow or if the weld puddle is lost, the welder slows down the speed of travel. Welding in the vertical or overhead positions is typically slower than welding in the flat or horizontal positions.
The welder must add the filler rod to the molten puddle. The welder must also keep the filler metal in the hot outer flame zone when not adding it to the puddle to protect filler metal from oxidation. Do not let the welding flame burn off the filler metal. The metal will not wet into the base metal and will look like a series of cold dots on the base metal. There is very little strength in a cold weld. When the filler metal is properly added to the molten puddle, the resulting weld will be stronger than the original base metal.

thread_title:  Copyvio? 

message: The article needs either a section or a reference to the types of torch kits commonly available. It needs to answer the question: "What distinguishes a Victor-style torch from a Harris-style torch?" Also: why are both types still produced? Why would one be more suitable to a particular job than another? Steve8394 (talk) 02:37, 1 April 2015 (UTC)
